General

What does LED stand for?

LED is short for light-emitting diode.

What other factors should be considered while buying?

As we discussed in our article on task based lighting, color temperature of the bulb should be considered based on the mood to be set in the room. LED bulbs are available in various color temperatures: Cool Daylight (White) to Warm White (yellow). Choosing the right one based on the mood to be set in the room is important.

Do LED Light Bulbs Contain Mercury?

No. LED bulbs do not contain mercury. They can actually be recycled as they do not contain hazardous substances and are manufactured without hazardous substances.

How do LED light bulbs compare to CFL bulbs?

Studies show LED light bulbs use 50% less energy than CFL bulbs and in many cases last 10 times longer than CFL light bulbs. They are much more durable, environmentally friendly, vibration and shock resistant, and offer excellent light quality - both indoor and outdoor.

Why are LED lights more expensive?

LED light bulbs use an actual circuit board to operate and are made of electronic components. Essentially, they could be considered an electronic device. This technology continues to gain advantages almost daily. The manufacturing as well as supply and demand of general lighting products are gearing up today, and we will see costs continue to decline as the adoption rate of LED Lighting increases.

Is LED light a different type of light?

Yes, LED light is said to be a safer, healthier light. LEDs do NOT produce any sort of ultraviolet radiation which causes color fading in Art, and fabric fading in carpeting and other soft goods. With LED Lights, there is no 'buzzing' or 'flickering' that many people are sensitive to. Residential and especially commercial and industrial plants, stores, libraries, galleries, and warehouses can immediately benefit from LED Lighting.

Can LEDs be used with dimmers?

Usually, yes. Many LEDs are specifically listed as being dimmable. Some dimming systems work with LEDs better than others, so it's best to test one or two before completely re-lamping a space.

Why do LEDs cost more than other types of bulbs? Are they worth it?

LED is still a new technology, and the expense of producing quality product is still high. However, pricing has come down dramatically from just a few years ago and prices are expected to continue to drop. In terms of whether LEDs are worth the extra cost, it's helpful to look at the cost to operate a bulb in addition to the up-front cost. The energy savings realized in a switch to LED means that the extra up-front cost is often paid back rather quickly, and you'll wind up saving money over the life of the bulb. If you'd like to see this in action, check out our Energy Savings Calculator. Here is an example: for a residential customer who may have the light on for just 10 hours per week ñ the payback is over 10 years. On the other hand, a retail or restaurant client who is burning lights for 90-100 hours per week will calculate their payback on a $70 LED PAR to be less than 18 months. Taking a look at your payback estimate should definitely be a consideration when deciding if LED is right for you.

How do some LED bulbs available in market have more than 120 beam angle?

Lot of LED bulbs available in the market have diffusors to disperse the light at greater angles. This makes sure that the light spreads across the room. But their brightness will be equivalent to a CFL bulb of same wattage. These are generally designed as replacement for CFLs and incandescent bulbs.  The benefit of these bulbs is that they are long lasting and ecofriendly.
