LED FAQ'S

What does LED stand for?

LED is short for light-emitting diode.

What Is the life of an LED

LED'S are not  lifelong durable but many of them has a durability of 50,000 Hours. and this is approximately 50 times longer than incandescent lamps, 25 times longer than halogen lights, 8 to 10 times longer than CFL. used 12 hours a day. A 50000 hour lasting bulb will last more than 12 Years. and if it using 8 hours per day will last up to 17 years.

Where we should use LED

It can be used almost everywhere. But remember  the intensity of light available in the room  either it is LED or CFL is directly proportional to the colour of the paint using the particular room and the location of the bulb placed. 

What are the advantages of switching to LED? 

There are a plenty of advantages to switch to LED
1) Durability  

2) Energy Efficient

3) Produce very little heat

4) It do not emit UV or Infra-red

5) Not Contains Mercury 

6)It can operate effectively from cold environment 

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, 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. 

Is there really any difference between a low cost  LED and a costly  LED?

Yes. LEDs are very similar to consumer electronics and quality really matters. In order for an LED to function properly and provide an acceptable light output, all of the components must be built to last. It's always a good idea to buy from a manufacturer and retailer that you're confident will stand behind the product. If you'd like to learn more about the components and how cheaply-made LEDs stack up against top-quality product.

Is an LED going to produce enough light to replace my current bulb?

For most applications, yes. Off-the-shelf LED products are now reliably replacing incandescent equivalents of up to 100 watts, and specialty products are available to replace even higher wattages. 

What's the quality of LED light?

If you buy quality product, the light quality is excellent. Color Rendering Index (CRI) is generally used to measure light quality on a scale from 1-100. Most LEDs have a CRI rating of at least 80, and many are rated 90 and above.

How green are LEDs?

LEDs are very green. For starters, they use much less electricity than many other lighting products. This means that less electricity has to be produced to operate them, and resulting in lower emissions from power plants, especially in areas where coal-fired plants are common. Unlike CFLs, they contain no mercury. Because of their long life, they also reduce solid waste: If you replace an incandescent bulb with an LED, you will prevent fifty 1,000 hour incandescent bulbs from being thrown away. Additionally, they produce very little heat and can reduce energy usage related to HVAC. The U.S. Department of Energy has estimated that increased adoption of LEDs over the next 15 years would also reduce electricity demands from lighting by 62 percent, prevent 258 million metric tons of carbon emissions, and eliminate the need for 133 new power plants.

 Should LEDs be used in enclosed fixtures?

Not if they are completely enclosed. In order for an LED to function correctly, they must be in a non-enclosed fixture to allow for heat to dissipate from the heat sink. Otherwise, they can overheat and may fail early.
