Who are the key manu's of spec-grade
retrofit LED bulbs available on the market?
Like Tim said on another thread, it's like starting all over again. I was annoyed at some retro bulbs I bought this summer from my distributor that did not include much on specs or recommended info on voltage range for installation. I didn't see optimal voltage or even a safe range in the paperwork. I'm certain it most likely matters, and that is going to be different from one LED manu to another, as the electronics, drivers, and assembly components are very different from manu to manu.
