With its combination of energy savings, durability, and low profile construction, the light-emitting diode (or LED) has quickly become the lighting technology of choice. The fast and furious way in which it came to market—without giving pause for the industry to develop standards—has resulted in some missteps that have caused problems with premature failures, flicker, and poor color quality.  The industry has responded by developing new standards which most, but not all, manufacturers have embraced. It is important to specify products that are tested in accordance with industry safety (UL) and performance (IES) standards. This article is intended to help laboratory managers, equipment vendors, and specifiers understand some criteria that should be considered when incorporating lighting into the laboratory environment. The potential for energy savings and lower maintenance costs has brought LED lamping to the forefront of design conversations with building owners. The U.S. department of energy reports, “Widespread use of LED lighting has the greatest potential impact on energy savings in the United States. By 2027, widespread use of LEDs could save about 348 TWhr (terawatt-hour) ...
