Shedding the Light on San Francisco's Low Voltage Halogen Lighting

Low voltage halogen lighting brightens up many houses in San Francisco, both inside and outside. Low voltage systems are popular because they have many applications, typically have a long life span, and require less energy to operate than standard lighting fixtures.

There are new types of lighting that are coming onto the market, especially light-emitting diode technology that is known as LED. At the moment, LED technology remains quite expensive, and the devices have yet to prove that they can last for the extremely long periods that are promised....

Low voltage halogen lighting brightens up many houses in San Francisco, both inside and outside. Low voltage systems are popular because they have many applications, typically have a long life span, and require less energy to operate than standard lighting fixtures.

There are new types of lighting that are coming onto the market, especially light-emitting diode technology that is known as LED. At the moment, LED technology remains quite expensive, and the devices have yet to prove that they can last for the extremely long periods that are promised.

For the homeowner, low voltage halogen remains a popular and cost effective option that reduces energy use in and around the home. The initial cost may be slightly higher than with standard incandescent fixtures, but the energy savings add up over the lifespan. Let's see how low voltage halogen may be used.

Finding out What Low Voltage Halogen Lighting Means in San Francisco
"Lamp" means light bulb - the lighting industry generally refers to a light bulb as a lamp. Halogen lamps are incandescent lights, like the standard light bulb or lamp. Standard incandescent lamps include a filament of tungsten. As the lamp burns, the tungsten gets burned off the filament and usually deposited on the bulb. The bulb is the glass enclosure that surrounds the filament.

By contrast, in a halogen bulb, the tungsten is burnt off the filament, but gases in the bulb cause the tungsten to re-deposit on the filament, increasing the lifespan. The glass bulb, or envelope, also remains cleaner. Halogen lights offer better luminous efficiency, meaning they produce more light for less energy than standard incandescent lamps. Halogen lamps also offer better color temperature than standard incandescent lamps. Color temperature refers to whether light seems warm or cool. Warm light is often more desirable and attractive in the home and has reddish undertones. Cool light has bluish tones and is generally thought to be a starker, more clinical light.

The halogen lamp filament has an envelope, or bulb, made out of quartz or any other glass with a very high melting point. This envelope is very strong, which allows for greater gas pressure within the bulb, which in turn slows the rate at which the tungsten evaporates off the filament, which increases the light output, or efficacy, for the lamp. Halogen lamp manufacturers generally recommend that envelope of the halogen bulb not be touched. Doing so can create a hot spot that heats quickly when the lamp is on. The hot spot then transforms from strong quartz to a weaker form that allows gas to escape. The hot spot also has the potential to become a bubble that results in the bursting of the bulb. If you do handle the halogen lamp's envelope and leave marks, it's recommended that you wash the marks off with alcohol, then allow to dry completely before using the lamp.

Lighting Up San Francisco With Low Voltage Halogen Lighting
Low voltage lighting serves many purposes in San Francisco homes. Within the house, you may be creating your own lighting design. Typical lighting designs address three kinds of lighting. First, there is general lighting, also called ambient lighting. This lighting is what allows you to see your way around your home. The American Lighting Association recommends that each room in the house have at least one central source of general lighting. Then, there is task lighting. You may not need separate task light. For example, in the laundry room, general lighting may be perfectly adequate for doing the task, with no additional light needed. But in some cases, you may want specific lighting for tasks like cooking, reading, sewing, paying the bills, or doing homework. This task lighting should make it easier for you to perform the task but should not strain your eyes or cast unhelpful shadows. The third kind of lighting in a lighting design is accent lighting. Accent lighting allows you to bring attention to some special object or space - you may have art you want to show off, or you may have a particularly attractive wall covering, or a special plant. Advice varies, but accent lighting is typically designed to be three to five times brighter than standard lighting so that it effectively spotlights the chosen object.

Low voltage halogen lamps suit general, task, and accent lighting in San Francisco homes, whether in the Tenderloin, the Sunset District, the Richmond District, Bernal Heights, the Mission District, Pacific Heights, the Excelsior, or the Bayview District. Low voltage halogen light fixtures often appear as "cans" recessed into the ceiling. Or low voltage halogen light fixtures may be placed on tracks, cables, or other devices that allow you to add light fixtures or move the light fixtures easily. Low voltage halogen lamps are often small in size. In fact, low voltage halogen lamps were originally used in projectors, in part thanks to their small size. Halogens remain popular for theater floodlights and other stage lighting. In part thanks to this history, halogen lamps are very good at creating directed light that can be focused on a specific object, making halogen lamps ideal for accent lighting. The MR16 halogen lamp is particularly good at when used in task lighting because the lamp's mirrored reflective surface helps direct the light forward.

Low voltage halogen lighting finds its place in many rooms. As mentioned, cans recessed in the ceiling are popular, as are track or cable lighting. In track or cable lighting, the cans are placed on a track or a cable that sends power to the cans. You can easily add or remove cans from the track or cable. You can also change the positioning of the cans. Part of your lighting design will focus on how the light fixtures will be placed around the house. As you shop for low voltage halogen lights, you will find many places to use them. In cabinets, low voltage halogen lights are often used for lighting special objects or simply to light the interior of the cabinet. No matter where you add low voltage halogen lighting in your house, you'll find it casts a useful glow.

Shopping San Francisco for Low Voltage Halogen Lighting
As you plan the lighting design for your house in San Francisco, you'll have a lot to keep in mind. You'll not only be deciding where you want the lights to go so that they serve the appropriate tasks, you'll also be considering the lamps themselves. Halogen lamps, including low voltage halogen lamps, are prized because they have a warm color. Other lamps, such as fluorescent lamps, tend to provide a cool color. Fluorescent lamps are often coated on the inside so that they initially give off a warmer light, but over time, this coating wears off. Halogen lamps are also very good at directing light. You may end up considering the beam width of the lamps and lighting fixtures that you are considering. You can think of beam width in terms of spotlights or floodlights. A spotlight has a narrow beam width and focuses on only one place, while a floodlight cast light over a broad area, thanks to a broad beam width. You may decide on a narrow beam width for task lighting, while a broad beam width may suit for general lighting purposes.

The electricity that enters your house comes in at 120 volts. Low voltage halogen systems operate at around 12 volts, typically. Low voltage halogen lighting systems include transformers that convert the 120 volts to the 12 volts the low voltage halogen lighting system needs. For most interior applications, the transformers are included as part of the low voltage halogen fixture itself.

The dimmer has an important role in a low voltage halogen system. Low voltage halogen lighting systems need dimmers designed especially for them. These may be electronic dimmers or the older, heavier dimmers. In either case, you need to be sure that the dimmer you select will operate with a low voltage system. Dimmers have come to play an important part in lighting design. As you know, a dimmer allows you to increase or decrease the amount of light coming from the light fixtures. Using a dimmer may reduce energy costs and may also extend the life of the lamps, since a reduced amount of energy passes through them.

Dimmers are also useful for increasing flexibility in a single room. The same room in a home may be used by many people for many different tasks, at many different times. It can be difficult to know how to light such a space. One person may need lots of general light, while another will just need specific task lighting. One person may prefer a brighter room, while another person prefers less light. One solution to resolve such a lighting dilemma is to make the room as bright as the most demanding task and person require, then use a dimmer so that lights can be dimmed or brightened by others on demand.

In California, dimmers are basically required for many lighting designs. The California Title 24 outlines energy use in the residence - as well as other places. The latest set of guidelines was written in 2008 and is now in effect. The guidelines highlight different areas of the house, like the kitchen, bathrooms, and bedrooms. For each identified area, the guidelines offer specific requirements. For example, in the kitchen, at least 50% of the lighting must be from high-efficiency sources. If you are mixing high-efficiency and low efficiency sources, they must be on different switches. In addition, dimmers that recognize when there is no movement are required in some areas, so that lights will dim if no one is present. All the details appear in Title 24 of California's energy laws.

San Francisco Lights Up Outdoors Using Low Voltage Halogen Systems
In addition to indoor uses, low voltage halogen systems are very popular in San Francisco yards and gardens. Low voltage halogen lighting in the garden has many of the same benefits as in the house, including lower energy costs over time and flexible installation. Again, the energy available for use in a residential yard or garden is going to arrive at 120 volts. This line energy, also called mains energy, has to be treated very carefully. If you use the line energy to power your outdoor lighting, the cables carrying the electricity must be buried deeply, probably around 18 inches, or sealed into special conduits. The lines must be absolutely waterproof to avoid shock, and severe damage and harm are possible if the electric line is cut or damaged. In contrast, low voltage halogen lighting in the garden uses a cable that can be lightly buried. It can get damp, and if it is ever damaged or split, there is little potential for harm, since it only carries twelve volts.

If you decide to install low voltage halogen lighting to light your landscaping, deck, or patio, it may take just a bit more than using low voltage halogen lighting indoors. Often, for outdoor lighting, you need to purchase a separate transformer. Remember that for indoor lighting, the transformer is often integrated into the light fixture itself. You must buy a transformer that can support all the wattage you plan to run off it. Examine all the fixtures you plan to run off a specific transformer, add up their wattages, and make sure the transformer is rated to support that much wattage. Some also buy transformers that are slightly more powerful, to allow for growth. You can also use multiple transformers, placed appropriately so that they supply full power to all fixtures.

As you situate lights around your outdoor space, you may notice that some lights are dimmer than others. The dimness is a result of voltage drop. Voltage drop occurs when not enough power is getting to a specific light fixture. If you don't mind some fixtures being dim, all is good. If you do want uniform brightness, you can try reducing the number of light fixtures that one transformer supports. You could also reduce the distance between the transformer and the light fixture, or you could try using a thicker cable between the light fixtures. Another option is to add a more powerful transformer or simply have multiple transformers.

If you want quality from a low voltage halogen lighting company in San Francisco and the greater Bay Area, you can have confidence choosing a Diamond Certified company. Diamond Certified reports are available online for all certified companies. And you'll never be fooled by fake reviews. That's because all research is performed in live telephone interviews of actual customers.

If you can't find a Diamond Certified low voltage halogen lighting company within reach, you'll have to do some research on your own. If you do, it's wise to call some references provided by your Low Voltage Halogen Lighting. Keep in mind, though, that references provided to you by the low voltage halogen lighting company are not equal in value to the large random sample of customers surveyed during the Diamond Certified ratings process. That's because references given to customers from companies are cherry-picked instead of randomly selected from all their customers. So the contractors will likely give you a few customers to call that they know are satisfied.

If you do call references on your own, specifically ask for a list of the company's 10 most recent customers. This will help avoid them giving you the names of only customers they know were satisfied.

  1. Did you do any work outdoors with low voltage halogen lighting on your own? Was the lighting company helpful?
  2. Did your San Francisco low voltage halogen lighting company seem familiar with the requirements of California Title 24? Did they make sure the lighting complied with the energy efficiency standards?

  7. If the San Francisco low voltage halogen lighting company offered help with designing your lighting, did the design meet your needs? Does the finished product provide light that doesn't strain your eyes or create shadows?
  8. What did your low voltage halogen lighting company provide? Did you buy materials, or did you also get help with lighting design and/or with installation?
  9. Did the San Francisco low voltage halogen lighting company offer help if you wanted to install the outdoor lighting yourself?

You must decide what you want to ask your San Francisco low voltage halogen lighting company to provide. Are you looking for products or services or both? If you are only buying products, then look for a firm with a history of doing business in San Francisco and that has the products you want.

If you decide to hire a San Francisco low voltage halogen lighting company for installation or other services, treat the deal as you would when you hire any contractor. Generally, the services from a lighting company would include lighting design and installation of the lighting fixtures. If you are getting design help, make sure you understand how much you have to pay, if anything, for the design. Do you get a copy of the design if you eventually decide not to use the same low voltage lighting company? Or do you only get the design if you continue to work the same company?

If the San Francisco low voltage lighting company is doing the installation, make sure you get written estimates from competing firms. Look for detailed estimates that provide information about products, labor costs, and completion dates. Do not begin a construction project without a written contract.

For projects in California, the people installing your low voltage halogen lighting systems need licenses. There are several kinds of licenses that may be applicable. An electrician could install electricity-related good. There is a C-7 license specifically for installing low voltage landscaping lighting. A person with a landscaping license may also be able to install low voltage landscaping lighting, since the Contractors State License Board allows those with a license covering a broader range to sometimes perform tasks that are covered under a more narrow license, as long as the tasks are part of the bigger project. That means, a landscaper can sometimes build a wall or install low voltage lighting as part of the landscaping, even if the landscaper doesn't have a specific masonry or low voltage installation license. The most critical thing is to look for a licensed professional.

Make the Task go More Smoothly for Your San Francisco Low Voltage Halogen Lighting Company
You'll decide how big or small a role you'll play in your low voltage halogen lighting installation in San Francisco depending on your interests and abilities. But no matter how involved you choose to be, whether you project is in the Tenderloin, the Sunset District, the Richmond District, Bernal Heights, the Mission District, Nob Hill, Pacific Heights, or the Excelsior, a little organization from you can help. It's a good idea to know the plans for installing the light fixtures. If there were previous problems, you should have a grasp of them. That way, you can offer useful responses if questions come up. The more quickly and completely you can respond to any questions, the better the design and installation can go, so make it easy for your San Francisco lighting company to get in touch with you. Always respond as promptly as you can.

Given their ability to produce light effectively, to direct that light where desired, and to provide good quality light, low voltage halogen lighting is very effective for task lighting.

Landscape Lighting
When you want to light up your landscaping, low voltage halogen lighting is a good choice because it is relatively easy to install, is flexible enough to allow you to change the position of lighting fixtures, and the voltage of the electricity used is low enough to work well in the outdoor environment with rain, snow, and other wet weather.

Reduced Energy Costs
People choose low voltage halogen lighting because over time, the amount of energy used is less. In turn, this reduces the cost of lighting the building or landscaping.

Cabinet Lighting
Low voltage halogen lamps can easily be placed in cabinets so that the entire cabinet or specific pieces in the cabinet are well lit.

Flexibility
Whether it is an indoor track lighting system or an outdoor landscaping lighting system, many low voltage halogen lighting systems are flexible, allowing you to move light fixtures or to add or remove light fixtures relatively easily.

Path Lighting
For paths - either around residential structure or commercial buildings - low voltage halogen lighting allows the owner to make the path safer while reducing the amount of energy used.

General Lighting
Low voltage halogen lamps provide enough light to serve as the main source of lighting in a room.

Improved Lifespan
Low voltage halogen lamps last longer than standard incandescent bulbs. This reduces the amount of money spent on replacing lamps.

Easy Ways To Prevent Problems with San Francisco Low Voltage Halogen Lighting Companies
You have several possible courses of action you can take if you have disagreements with your San Francisco low voltage halogen lighting company.

Of course, you want to work out the problem between yourselves, if you can. If not, if you only bought products, you can report the company to the Better Business Bureau.

If you also bought installation services from the lighting company, you can file a complaint on the California Contractors State License Board (CSLB) website. The CSLB may not fight to get you money back. However, it may order work to be finished or for another company to finish the work. But if you want to get money back or restitution for a poor job, you should go to San Francisco small claims court.

accent lighting
Refers to lighting that is used to draw attention to a specific item, perhaps art or a plant. In general, effective accent lighting is four-five times more than the ambient light.

a-line lamp
An a-line lamp is the term for an incandescent light bulb.

alternating current
Alternating current is the way most houses and buildings get their electricity; the alternative is direct current. An alternating current is a circuit that changes direction every second. In the United States, alternating current typically cycles through direction changes at a rate of 60 cycles per second.

Also known as: AC

ambient lighting
Refers to the basic lighting that radiates through a room or other space.

area lighting
In landscape lighting, refers to illuminating large areas of the landscape, often with floodlights.

baffle
A baffle is a surface that helps prevent reflected glare from light and helps guide the path of the light. It is often a grooved surface. Recessed lights that focus downward often have an integrated baffle.

ballast
Refers to a device that is used to start a fluorescent or high density discharge (HID) light bulb but which also limits the current used during standard operation.

barn doors
Refers to plates attached to the sides of a light. The plates are opaque and direct the light to a specific area.

base
The part of a light bulb that allows it to electrically and physically connect to the socket.

bayonet base
Refers to the base of a light bulb that has pins that plug into the socket, instead of a base that screws in.

beam spread
Refers to how broadly or narrowly light diffuses. For example, the beam spread may be a narrow spotlight or a wide floodlight. The beam spread is produced from a light bulb with a reflective coating that directs light forward.

bulb
A bulb is one term used to describe what the lighting industry calls the lamp, aka a light bulb. In lighting industry terms, the bulb is only the glass envelope of the lamp.

cable lighting system
In low voltage lighting, a device in which cables both supply the electricity to the light fixtures and secure the light fixtures in place.

candela
A unit of measurement that indicates a light's luminous intensity.

Also known as: cd

cathode
An electron-emitting electrode. Fluorescent lamps (light bulbs) include cathodes at either end.

cave effect
A generally unwanted condition when the lighting fixtures do not supply light to the upper walls in a room.

CCFL
A cold cathode fluorescent lamp. A fluorescent lamp in which the cathode does not get independently heated.

colored glass filter
A filter that is used primarily for decorative purposes - they will not control the light bands. For colored glass filters, the color is actually incorporated into the glass as it is being made and is not applied later as a surface coating.

color rendering index
Refers to how well a lamp (light bulb) can produce accurate colors. The sun has a CRI of 100, while low pressure sodium has a CRI of 1. Lamps with a CRI of 85 are thought to be very good.

Also known as: CRI

color temperature
Refers to whether a light appears warm or cool. Warm light has reddish tons, while cool light has bluish tones.

compact fluorescent lamp
Broad term used to cover a range of fluorescent lamps that have one base and spiral, folded, or bridged glass tubes. They have a high CRI and a long lifespan.

Also known as: CFL

dimmer
A device that is used to increase or decrease the brightness of lamps in lighting fixtures. Dimming incandescent, halogen, and xenon lights can decrease energy used and improve the life of the lamp.

direct current
Refers to electricity that flows without changes in direction (alternations). Typically created by a transformer, battery, or by photovoltaic cells.

downlight
Refers to a light fixture that is placed into a recess in the ceiling and that spends light downward.

Also known as: recessed downlight, can, recessed can

efficacy
Measures how much light is put out in comparison to how much energy is used. It is measures as lumens per watt.

filament
The wire made of tungsten that illuminates when in contact with an electric current.

MR16 lamp
A kind of halogen lamp (light bulb). It has a mirrored reflector that helps send out a sharp beam of light in the desired direction. It is 16/8, or two inches, in diameter.

PAR lamp
A parabolic aluminized reflector. The light that the reflector directs out is parabola-shaped. Both the internal reflector and prisms in the lens are responsible for guiding the light.

transformer
A device that converts the normal line voltage running into a house or commercial building into a voltage suitable for low voltage systems.

voltage drop
Refers to a loss of power, or voltage because there is resistance from the wires and light fixtures on the circuit. To prevent voltage drop, you can use a DC transformer, make the distance between the transformer and the light fixtures shorter, or use a thicker wire.

Q: Do I need a licensed contractor to install low voltage halogen systems?
A: California has a specific licensing classification for low voltage lighting systems. The C-7 license specifically allows the holder to install low voltage systems in landscapes, as well as other low voltage and communications devices. A licensed electrician should be able to install low voltage systems in the house.

Q: Why are low voltage halogen systems so attractive for outdoor use?
A: There are a couple of advantages to using low voltage halogen systems for highlighting your house and landscaping. First, the lighting fixtures are pretty easy to install, and they can be moved around when plants grow or if you decide you would like a different effect. The low voltage cable used to supply power to the fixtures can be installed in a shallow trench, in a conduit, or even buried. Typically, if the low voltage cable is accidentally cut, there is little damage. This is in contrast to a line carrying the full electrical charge which generally requires deeper burying - at around 18 inches - and can be dangerous when damaged. Low voltage systems can tolerate damp, while a full voltage system must be absolutely waterproof to prevent shocks.

Q: What does low voltage mean, anyway?
A: When referring to lighting, low voltage typically refers to systems that operate on an electrical supply of 12 volts. When electricity comes into residential buildings, it typically comes in at 120 volts, in the United States. With the use of a device called a transformer, the electric current is reduced from 120 volts to 12 volts.

Q: Do I always need a transformer for low voltage halogen lighting?
A: Yes, but you don't always have to buy it separately. For some low voltage halogen installations, particularly when you are landscaping, you will need to buy a transformer. This transformer will reduce the electricity from the 120 volts at which electricity enters residential premises to the 12 volts, which most low voltage halogen systems use. When planning your landscaping lighting, you need to be mindful of how many lights you want to install and make sure that you get a transformer that will support the total watt load of all the lights you want to install.

When you use low voltage halogen indoors, it is often in "cans" or light fixtures that can be recessed into the ceiling, placed on tracks or cables, or installed as in-cabinet lighting. The indoor lighting fixtures often have the transformer incorporated as part of the fixture.

Q: What is voltage drop and how can it impact me?
A: When you are installing low voltage halogen lighting systems, for example in your landscaping, you may notice that some lights are less bright than others. This is a sign that the voltage has dropped - in effect, less voltage, or power, is getting through to the dimmer lights. If you do not mind the dimmer lights, you don't have to do anything. In fact, those lamps (aka light bulbs) that are running dimmer will tend to last longer because they have less voltage running through them.

If you want uniform brightness, you need to make the distance between the transformer and the light fixture less. Or you can use a heavier cable wire, or reduce the number of fixtures or reduce the number of watts used on each fixture. You can also add a transformer or use a more powerful transformer.

Q: Are LED lights better than low voltage halogen lights?
A: There is not currently a clear answer to this question. LED lights - based on light emitting diode technology - promise to consume less energy that low voltage halogen lights and to last for a very long time. However, it is not clear that the claims of extremely long life can be backed up. It's also worth noting that sometimes you need several LED lights to get the effect produced by a single low voltage halogen lamp. Also, LED tends to cast a much cooler light than halogen. LED lamps are typically coated to help them produce a warmer light, but over time this coating wears out and the light from the LED becomes even cooler. In general, a warmer light is preferred for homes.

Q: Why should I care about color temperature?
A: Color temperature refers to the perceived warmth or coolness in light. A warm light has reddish undertones, while a cool light has bluish undertones. A warmer light is generally perceived as more friendly and welcoming. Cool light is generally reserved for spaces where very crisp lighting is desired - medical examining rooms, jewelry stores, and other places where cool, crisp edges are desired.

Q: What kind of lighting would I find in my house?
A: In general, there are three kinds of lighting to consider adding to your home, indoors. General, or ambient, lighting provides overall lighting to the home or space. It lets you see and move around safely. It's a good idea to have a central ambient light in each room. A more focused kind of lighting, task lighting provides a concentration of light for a specific purpose - grooming, cooking, doing homework, etc. It should be glare-free and without shadows. Accent lighting is used to bring attention to a specific object or feature - maybe a painting, or a vase, or an interesting wall. An accent light should be at least three times stronger than the general light in the room.

Q: Why are dimmers so frequently mentioned?
A: Dimmers are devices that allow you to increase and decrease the amount of light that a fixture puts out. They are popular because dimming lights can not only reduce the cost of the energy you use, it can also extend the life of the halogen bulb. In addition, dimmers help when there are problematical lighting designs. Different types of people may be using the same space for different purposes. Some need more and some need less light, at different times. One popular approach to this issue is to "over light" a room - that is, to put in the most amount of light that will ever be needed - and then use dimmers to control the lights when the complete brightness is not required.
