CFLs are great except that I can't see anything when I used them. They would be better if they actually provided light. But they do cost more, don't really last much longer, take American jobs to China and the process of making them is harmful to the environment so I guess all in all they are worth it......to the manufacturers.

And, yes, fewer insects. This is a summary of a study out of the University Of Georgia Department Of Entomology:

In short, the research indicates that since insects are attracted to UV light, and Cree LEDs emit little or no power in the UV spectrum insects just aren’t interested and a less interested bug means fewer bugs present where Cree LED’S are used, period. The article states, “Color sensitivity in the UV spectrum plays an important role in foraging, navigation, and mate selection in both flying and terrestrial invertebrate animals. This attraction to UV light has made insects a useful model for understanding visual sensitivity to UV light. Cree LEDs emit little or no power in the UV spectrum. Incandescent, fluorescent, and metal halide sources emit a substantial amount of UV radiation, thus it is likely that bugs are less attracted to fixtures utilizing Cree LEDs.”

DISCLAIMER: I have no financial relationship with Cree, I'm just a fan.

I have no doubt that LED lights are the wave of the future. However, I did a rough count in my home and found that I use more than EIGHTY light bulbs inside and out! Given the cost of LED lights, there is no way I could replace every bulb, at least at this point.

The thirty-second warmup is trivial to me, and I've never used dimmer switches. We all have different needs and wants.

I am happy just to have gotten rid of the heat-producing incandescent bulbs that go back to the days of Thomas Edison and that burn out so frequently. And I might add that the last incandescent bulbs I bought WERE made in China....

As far as mercury is concerned, as pointed out in an earlier post, we've been dealing with this issue for decades with the use of fluorescent tubes. Is it more of a problem now (other than the fact that it was easier to break a long tube than it is a CFL ("C" meaning "compact")?

LED lights will come down in price with competition. I'll be interested when they're more affordable. Meantime, the change shows in my electric bill presumably on both fronts--lower lighting costs AND lower a/c costs. And nowadays it's a rarity that I'm up on a ladder changing light bulbs--and THAT'S a relief!
