First note that I have recently chosen to moderate comments since most are spam, and some quite awful. I am so happy to accept this comment, where in most posts I get no contribution. I want to be part of a process of invention to do better in our homes, in some more wiki-like site inviting of multiple authors. I want all authors then to be identified if they wish. I want to recede, and to even accept original posts from others, properly attributed.<br /><br />I suspect you have much more to share here about tragedy that LEDs are being pushed as light bulb replacements losing at least half of potential efficiency in advantage over point-source incandescents. I think we need to strongly express the message we can reduce electricity demand more than 90% while doubling illumination, as well-placed overhead downlights. Go further to wire each light as direct current from central and serviceable clever and inexpensive converter electronics. Simple DC luminaires will last forever and must never require service as in bugs removal. Can you confirm that circuit boards with elements other than LED diodes will shorten service life, commensurate with a 3-year limited warranty here?Phil Normanhttps://www.blogger.com/profile/05985383574850078234noreply@blogger.comtag:blogger.com,1999:blog-1824943627340897655.post-61240108765162241372017-11-17T13:48:04.818-08:002017-11-17T13:48:04.818-08:00Regarding longevity of LED lighting: Even more tha...Regarding longevity of LED lighting: Even more than with CFL, the weakness is in the electronics. LEDs do generate waste heat, and neither they nor their supporting electronics tolerate heat well. An incandescent throws lots of heat, but it can live at quite an elevated temperature. If an LED's electronics get hot, they die young.<br />If fixtures were built with decent heat dissipation, the LED assemblies would probably live forever.Unknownhttps://www.blogger.com/profile/13700778691727235897noreply@blogger.com
