I saw the title of the thread and got all excited, but nobody has addressed the issue that troubles me. I cannot SEE with these awful replacements.
Where I live, it has been almost impossible to find a 100W incandescent for several years. In any event, I knew the end was coming, and so I started experimenting with different bulbs. NOTHING comes close to the efficiency of the now outlawed lighting I have enjoyed all my life.
My experience with LEDs has been even more disappointing than my experience with CFLs. Because the little desk lamp in my computer room, with its tiny bulb, puts out such nice bright light, I expected the same from whatever LED I put in my reading lamps. But, no. I cannot see. I read. I write, I work cross-word puzzles. I sketch. I paint my fingernails. And, what will happen when those big round bulbs that light my bathroom die? How will I see to apply make-up?
I haunt Lowe’s lighting section. They are tired of me, and my questions, and my returns. Packaging may say “Replaces 100W incandescents” but for light output, that just isn’t so. I don’t care about heat. I don’t care about electrical usage. I don't care about life span. I just want illumination.
For my reading lamps, which is what I really care about, 1600 lumens should work, but part of the problem is what Mouser said here:
3. Spotlight effect. The LED bulbs are more directional -- which can be especially troublesome for fixtures where the bulb is pointing up.
But I’ve also had noise and flicker from both CFLs and LEDs. Horrible, horrible, and no relief in sight.
