LED Lighting FAQ's
Questions you Should ask if you Think about When Transitioning to LEDs
I know it's an acronym, but what does LED stand for?
LED is short for Light Emitting Diode.
Where is an ideal place to use them?
There's no ideal place to use LEDs as they can be used just about anywhere, but most people prefer to use them in places that need light for an extended period.
How long do they typically last?
LED bulbs have a reputation of lasting longer than any other bulb. The typical LED bulb lasts as much as 50,000 hours which is roughly 50 times the lifespan of an incandescent bulb and approximately 20 times longer than the typical halogen. Even if the bulb is used 12 hours a day, the 50,000 hours is enough for LEDs to run for 11 years and 17 years if used only for 8 hours per day.
What are the other advantages of switching to LEDs?
LEDs feature a wide array of advantages aside from its significantly longer lifespan. LEDs consume less electricity compared to other bulbs, they also produce little heat as and they do not emit UV radiation. In addition, LEDs do not contain mercury, which is an added bonus for the environment conscious folks.
Am I doing the environment a favour by switching to LEDs?
Transitioning to LEDs definitely helps the environment by reducing emissions of greenhouse gasses due to the reduced electricity cost. In addition, the fact that LEDs do not contain mercury this makes disposing of the bulbs much easier and less damaging to the environment. Purchasing one led bulb is equivalent to saving fifty 1,000-hour incandescent light bulbs from being disposed of. Experts say that by transitioning to LEDs we can effectively reduce the demand for electricity by as much as 62 percent, which is enough to stop 258 million metric tons worth of carbon emission as well as kill the need for new power plants.
Will the prices of these bulbs drop?
Because LEDs are still new, the expenses in producing this high quality product is still very high. However, in recent years prices have begun to drop dramatically at a steady pace. It is expected that the prices will continue to drop in the coming years. With regard to the concern of whether these bulbs are worth the extra buck, it is helpful to observe how often you have to spend money replacing other bulbs when you can always save more with a one-time buy that will last for years. In addition, savings on your electricity bill and maintenance costs pay up the up-front cost rather quickly.
Are there any differences between LED bulbs that are priced differently?
As with many things in life, LEDs can only do what they claim if their components are built to last. There are companies out there that are just riding the popularity wave of LEDs so it is best to make sure you buy from a reliable manufacturer who known for providing quality products.
Are LEDs going to provide the same light output as my current light bulb?
For most cases, yes, LEDs will be able to provide the same light output as their incandescent cousins - even those up to 100 watts. There are special products available in the market right now that are being used to replace bulbs with even higher wattage output.
How good is the light quality of LEDs?
If you bought a quality product, the light quality should be excellent. CRI or Colour Rendering Index is used to gauge the light quality, which can vary within the range of 1-100. Typically, an LED bulb will have an 80 as their CRI rating some are 90.
Will LEDs work with dimmers?
Numerous LEDs are listed as dimmable and some systems made for dimming work with these bulbs better than incandescent bulbs and others.
Will an LED work in an enclosed fixture?
Unless they are completely enclosed, yes they will still work. However, should an LED be placed in a completely enclosed fixture, it may fail early due to overheat since the heat cannot dissipate properly from the heat sink.
