How bright are LEDs?
What is a Lumen?
Lumens are used to measure light bulbs as standalone light sources. Lighting fixtures are measured by lux output which is lumens per square meter.
Will LEDs match my current lighting in terms of color temperature?
When LEDs first hit the market they were limited in color options but again, the technology has progressed to the point where any color on the color temperature scale can be precisely matched.
Why do LEDs cost more?
The initial investments with LEDs are more than that of a traditional incandescent, fluorescent, or HID lamp because of the technology behind engineering the light source, the proper thermal dissipation unit, and the step down transformer when necessary. However, people who make the transition from traditional lighting over to LEDs will make their money back within 1-3 years of installing the LEDs because LEDs drastically reduce energy consumption, required far less BTUs to cool the units, and last exponentially longer which eliminates the need to constantly maintain the lamps.
How long does an LED light typically last?
LEDs will typically have a lifespan of 50,000 hours which at 24 hours per day 7 days a week will last 5.7 years- typical residential use is 3-6 hours per day meaning an LED will last 25+ years. Some LEDs will last 35,000 hours or even up to 100,000 hours depending on the type of LED and its manufacturer.
What type of LED lighting is available for homes?
LED lighting for residential applications will range from direct bulb replacements- can lights, ceiling fan fixtures, chandeliers, vanity mirrors, etc. – to under cabinet lighting, cove lighting, or any other type of accents lighting using LED strip lights.
How efficient are LEDs when compared to incandescent and CFL bulbs?
LED lamps are extremely efficient when compared to incandescent and CFL lamps. When replacing incandescent lamps one can reduce their energy consumption by up to 90%; the energy consumption reduction when switching from CFLs can be anywhere from 40-70% depending on the application. Not only will consumers see savings associated with energy consumption and on their electricity bill but they will see HVAC and maintenance savings as well. Since LEDs use less energy they also emit less heat when powered on this means that less AC is required to cool the units to maintain a certain temperature in a home or office. Also, the maintenance costs for LEDs will be considerably lower because they last so much longer than traditional lighting. So, there are numerous ways that LEDs are more efficient than incandescent and CFL lamps.
