The U.S. Department of Energy (DOE) has issued a final rule clarifying the test procedures for general service lamps (GSLs). These clarifications emphasize that GSLs shouldn't be tested as colored lamps, and if a lamp includes extra components not affecting light output, those components should be turned off during tests. For non-integrated lamps, the rule specifies testing with a ballast or driver that's compatible and commercially available, where possible. The final rule is designed to ensure consistent testing without imposing additional costs or burdens on manufacturers.
Simple Explanation
The U.S. Department of Energy has made a new rule about testing light bulbs to make sure they shine the right way, telling people how to test them without any extra parts turned on that don’t make them brighter. They also say which parts you should use when testing bulbs that need special devices to light up, using only ones you can easily get.
