LED Selection and Design Issues, Part 1

LED Selection and Design Issues, Part 1The industry has made a lot of hooplah about LED lighting, and with good reason. When properly selected, LED lighting provides many benefits including energy savings, reduced maintenance costs, and reduced relamping costs. LED also provides innovative lighting possibilities that previously weren’t possible.

Selection errors can wipe out many of these benefits. For example, suppose you want to light up the building’s perimeter. Prior to LED, doing so meant significant energy consumption. But with LED, it can mean significant maintenance costs. Unless the fixture is designed specifically for moist environments, it won’t be long before maintenance techs are climbing up ladders and scratching themselves on shrubbery to fix lights that went out “for no apparent reason.”

And even if you do get LED fixtures that can handle the moisture, did you specify fixtures that can handle the heat of prolonged sun exposure or are you going to leave it up to maintenance to recaulk those frequently? Will the techs know where to recaulk, or will they just guess and consequently close off the ventilation needed to keep the LED’s electronics from cooking?

The same logic applies to high bay lighting, an application in which LEDS are becoming increasingly popular. One reason for going with LED is the decreased interruption in operations due to increased interval between relampings. But if you underestimate the actual temperatures up on that ceiling space, you may be replacing LED units frequently until someone figures out that space needs LED units with a higher temperature rating.
