My problem with LEDS and CFLs is they do not change color when you dim them. The warmer colors you get from a dimmed incandescent is the whole point. I know they could do this with a color changing LED but at what cost? If I am happy with a $1.50 lamp that will last almost forever running at 75% power, why would I want a $50+ LED that uses almost as much power "dimmed" as it does full bright and may actually fail sooner. I never noticed that the LED bulbs are not "warmer" color-wise when dimmed. I guess that's not very important to me. The room just gets darker. The whole idea behind these types of bulbs is energy conservation, not romantic lighting. Replacing one 60 or 75 watt incandescent bulb with a LED bulb of equivalent lighting may not be huge, but replacing tens or hundreds of millions across the country sure is. Lighting makes up about 13 percent of average residential electricity consumption. Replacing the old bulbs as they burn out with LED equivalents makes sense to me. We've slowly been doing that over the past year or so and also replacing any of those stupid CFL type lights we have with LED types. The built-in ballast used in CFLs seem to pop as often or even more so than the incandescent filaments did. The LED bulbs I bought are made by Cree. They don't cost $50. They are $12.95. 800 lumen, dimmable, 25,000 hour life expectancy, 10 year warranty and consume 9.5 watts. I bought a few of those Cree bulbs at Home Despot. They seem to be working well. Haven't noticed any difference in the color of the room lighting. I confess I was a bit of a skeptic until I tried one. They work fine, to me. Proof will be in the pudding in terms of how long they work. The package I have says it will last 22.8 years at three hours a day until the bulb burns out. In 22.8 years, I suspect the bulb between my ears will dim, if not burn out entirely. I read somewhere...maybe it is a false memory...that you shouldn't put two of these bulbs in a multi-bulb fixture. But there's nothing on the packaging that says that. I'd like to find some "candleabra" LED bulbs. We have a zillion of them in the house and in our outdoor garage and porch fixtures. |
