This is a losing proposition. LED lights, and generally electronics built in some far east countries, are driven at 100% rating (or more) of the components used. That means that the electronics are stressed more than what we would expect and if we just use them more, like using LED lights in a home office, they’ll have a shorter life span. Dimming the lights may not help depending on the design of the circuit board in the LED light. Try to get “name brand” bulbs or assemblies and that might help. Clive of https://www.youtube.com/@bigclivedotcom has done many many videos where he hacks led lights where by removing a resistor increases the longevity of led lights. Caveat that he tends to do led lights he finds at his local PoundLand (he’s in the British Iles) which is akin to our dollar tree or dollarama. You should still be able to find “long life” incandescent bulbs but those will not save you energy, just save you from replacing them more frequently… YMMV. -- Jose Dias jose "dot" dias "at" DiasLan "dot" com From: talk <talk-bounces@gtalug.org> On Behalf Of Michael Hill via talk Sent: Wednesday, July 19, 2023 7:58 AM To: D.

My home office seems to burn out LED lightbulbs more quickly than it should. I don't know where to start on that one. It might even be heat related rather than power-related.) Would love to hear any conclusions to this. All of ours require a ladder to change, and change is generally required more frequently than the claim on the box. Mike
