I have been studying the different lights... Incandescences are cheap and give good warm and cool lights but 85% of the cost of running them is from the heat they produce.

3200 degrees kelvin - I used to be a photographer. Using 3200K balanced film in daylight yeilds interesting effects. Can't duplicate it with a digital camera AFAIK

The “squiggly” ones are also going to be phased out; which is fine with me ‘cause I hate them and they contain mercury.

In my expreience (see below) they don't last nearly as long as old-fashioned incandescent bulbs.

There is a light on the horizon coming into production that will be great when it finally gets here...it is the LEDs. They are expensive right now, but will cut your electric bill in half because they do not produce any heat at all.

Yep, as with all things give it time.

Also, they are suppose to last at least 10 years. Can you imagine not changing a light bulb for 10 years?

I do not have to imagine! My house was finished ten years ago this month and all but two of the original incandescent bulbs are still in service indoors[1]. One of the blown bulbs was in a fixture that arced and flickered badly, the replacement bulb in the repaired fixture is still in service. The second was whacked with a piece of furniture while moving said furniture.

In that time I have had at least half a dozen CFLs fail, some quietly and some with dramatic sound effects and burnt circuitry. Besides the CFLs, every florescent fixture in the house has failed at least once including the Circline® kitchen fixture and the 4'-tube laundry-room fixture.

All my bulbs were labelled "commercial service" and "130V" so they're not what one gets at Home Depot. I got more by finding out where the electricians stock up on supplies and buying them there.

Companies that have installed them are saying that they are saving from 50 to 85% cost on their lighting bills.

I'll garan-damn-tee you that people will quickly be complaining about the cold blue-white light LEDs produce.

Peet

[1] I have lost a bulb in a drop-cord, but lights slammed around under trucks don't count, do they? Also lost a couple OUTDOOR flood lights on the motion detector -- that stopped when I replaced the cheapo motion detector with a quality unit.

I bought some warm-white LEDs for my ceiling light. They work fine. As stated...they are expensive, but I hope I don’t have to climb a ladder for 10 years to replace them.

I’ve some squigglies in outdoor lights that are hard to get to, replacement wise.

About useless in cold weather until they warm up. May as well have a candle!

I’ve been noticing the difference in Christmas lights around my neighborhood already. And those are just for decoration!
