LED Lighting

Seems like one would be better off using two of the Philips 9W LED bulbs at 18W instead of the GE bulb at 27. Hopefully Philips will make a 100W equivalent soon for those who want one.

My first thought was, 'cool'. But then, how many normal 100w sockets do modern homes really have? Heck, most of what I'm trying to replace are Par38s and 48" tubes. I've got good replacements for both now (LEDWaves was having a sale on suitable Par38s, I found good 48" tubes at Polar Ray). Anything that takes a 'bulb' in the house really wants something 40We, ~400lm.

@SByer, I suspect the # of standard socket bulbs in a house is strongly correlated to when it was (re)built. My 1820 house has nothing but standard bulbs except in the kitchen and a few specialty fixtures we've installed over the years. My big gripe in shifting to non-incandescent bulbs is finding something that works in enclosed fixtures. O/w, I'm going to have to lay in a stash of bulbs before they become contraband!

If I were a manufacturer I would build the LED replacement for the biggest selling bulb.

Nearly all of the lighting at our home and office has been replaced with LEDs. I like rarely replacing them, even more, I like the idea that the light bulbs are not heating the space that I then have to cool with a/c.

Winter bulb, incandescent. Summer bulb, off for sun, on for LED.

Are there any good R40 replacement LED bulbs?

Depends on the situation. I've been happy with these for replacing the bulbs in the ceiling cans. Lumens are good, the warm white color is excellent, the 60° beam is only slightly narrower than I'd like, and at the sale price they're better than anything else I've found, but they're indoor only, and not every lighting situation could deal with the slightly narrower beam.

I've got two of the Philips AmbientLED 17W PAR38 floods - the warm white color is slightly too cool, lumens not quite as good, and a narrower beam (so, not really 'flood' in spite of the claim on the packaging). Found a spot for them, but they didn't work as a general can bulb replacement.

But then, either is better than any of the CFLs I tried.

Thanks. I was looking for indoor R40s in the kitchen (recessed cans). I bought CFLs to replace them but they burned out literally very quickly because I think the cans are insulated and the temp increased too much.

I put some dedicated CFL fixtures in a couple of years ago (the kind that have the ballast in the fixture, rather than in the bulb). The first bunch burned out very quickly but they seem to be making them better now and they are now lasting about as long as an incandescent bulb.
