Q&A

Q1: What does LED stand for?

A: LED is short for light-emitting diode.

Q2: How long do LEDs last?

A: LEDs are notable for being extremely long-lasting products. Many LEDs have a rated life of up to 50, 000 hours. This is approximately 50 times longer than a typical incandescent, 20-25 times longer than a typical halogen, and 8-10 times longer than a typical CFL. Used 12 hours a day, a 50, 000 bulb will last more than 11 years. Used 8 hours a day, it will last 17 years!

Q3: Where can LEDs be used?

A: They can be used almost anywhere. LED replacements are already available for bulb types such as A-Shape, PAR reflectors, MR reflectors, decorative, undercabinet, and more. When used on dimmers, particularly dimming systems that support many bulbs, we suggest testing a few LEDs first to test compatibility.

Q4: Why do LEDs cost more than other types of bulbs? Are they worth it?

A: 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.

Q5: What's the quality of LED light?

A: 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.

Q6: Can LEDs be used with dimmers?

A: 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.
