Types of Bulbs
LED (Light-Emitting Diode) – Most popular form of residential lighting. 6″ LED retrofit can lights use only 12 watts of power which is 85% less energy than an incandescent bulb, and 50% less than a compact fluorescent. LED bulbs last 50 times longer than the life of a typical incandescent bulb and 5 times longer than the lifetime of a compact fluorescent bulb. In fact, if you ran one LED bulb for 6 hours per day every day, it would last for nearly 23 years.
Incandescent – Once called a standard light bulb, most no longer meet the energy efficient standards in California. California Energy Commission banned the sale of inefficient light bulbs starting Jan. 1, 2020. You can still purchase General Service Lamps (GSLs) with an efficacy of 45 lumens per watt.
Halogen – A halogen light operates much the same as an incandescent, but halogen gas inside the bulb makes this light burn much more brightly, and they can be very hot to the touch. These lights are often used in jewelry cases, retail settings, portable projectors, landscape lights, and heating food. Most Halogen lights do not meet the energy standards in California.
Compact fluorescent light bulbs (CFLs) – The phosphor coating inside a fluorescent bulb glows when charged with electricity. A fluorescent bulb burns cooler and lasted longer than incandescent and halogen bulbs. Fluorescent bulbs are more efficient and cheaper to operate than incandescent and halogen bulbs. Linear is the other form of fluorescent bulb, often found in commercial or utilitarian settings. Fluorescents require a ballast, either magnetic (being phased out) or electric. Ballasts often fail in the fixture before the bulb. We always recommend installing a replacement LED fixture in these applications.
LED Retrofit Can Light Drivers
As new federal lighting standards go into effect, and traditional incandescent bulbs start to disappear from store shelves, homeowners will have some decisions to make about how to maintain their existing lighting.
For homeowners with overhead recessed can lights, LED retrofit drivers have become a very popular upgrade option because of their remarkable energy efficiency, minimal heat output, ability to dim, and lifespan of about 20 years.
Incandescent can light bulbs, typically 65 Watts, simply aren’t efficient – most of their energy is converted into heat rather than light. LED retrofit can light drivers, on the other hand, use about 10 Watts – almost of all which is converted into light.Homeowners who upgrade from incandescent can lights to LED retrofits will substantially reduce their energy consumption.
Energy Conservation Tips
Dimmers – By dimming the lights in a room, you use less electricity. For examples a light bulb at 50% brightness uses approximately 40% less electricity. A dimmer switch also extends the life of the bulb. A bulb at 50% brightness will last approximately 20 times longer.
Timer Switches – Using timer switches to automatically shut off bathroom lights and exhaust fans will reduce energy consumption. Digital timers are also used to control time intervals for both internal and external lighting.
Occupancy Sensors – An occupancy sensor will turn lights on when someone enters a room, and off after the person leaves the area. These are ideal for closets, hallways, laundry rooms and garages.
Motion Detectors – Leaving outdoor floodlights on all night can get expensive. Installing motion detectors, which react to body heat, greatly reduce the amount of energy consumption.
