[*]They do contain mercury (though as Klipstein points out, far less than regular fluorescent tubes, and their energy savings helps to reduce mercury emissions from coal-fired power plants, at least in theory)
Your math doesn't add up. 2000 hours of burning a 100W incandescent is 200KWH of electricity. Assuming about $.075 per KWH, that's 15 bucks for electricity, plus .31=$15.31
For the Halogen, 2000 hours of burning 72W is 144KWH. At the same price for electricity, that's $10.80 plus 4.98 = $15.78. The cost for using Halogen is only 47 cents more.
Since reading this thread and everything else - I'm trying to figure out just what I am going to have to replace my 4 foot tubular flourescents in my shop and garage with? I suppose I could get a bunch of light bases and use screw-in CFLs, but as others have noted, and in my experience - such an orientation (with the base above the lamp) tends to lead to a much shorter lifespan. I suppose that an LED-based tubular lamp could be bought (might already be possible to purchase - I haven't looked) - but such a lamp couldn't be cheap; I'll need four for my shop, and six for the garage. Maybe I should just stock up on the tubular lamps ahead of time. Sigh.
I don't care if the government sees any compelling reasons. A compelling reason to me might not be a compelling reason to you. A compelling reason to you might not be a compelling reason to the government. It's subjective, and we are becoming subjects. You might be Obsessive Compulsive. As part of your OCD, you may only make right hand turns while driving. You may drive all the way around the block to pull into a driveway right to your left. The government may (rightly) see this as inefficient, and thus have a "compelling reason" to enforce a left turn policy on you. but do they have the right?This issue cuts so many ways that it's a gross oversimplification to say that "the government is outlawing incandescents just because it can". This imputes that "the government" is just capricious, and that there aren't any compelling reasons to do away with incandescents.
really? I fail to see any connection between energy savings and the survival of the human race. If electricity disappeared tomorrow, I would be greatly inconvenienced, but I would be alive (for years to come). The human race survived for thousands or millions of years before light bills and we can do it again.There are: energy savings isn't just a good thing, but essential, in the overall scheme of things, to the survival of humankind.
Hi Crosh
As it stands now it is only incandescent bulbs facing extinction. Standard fluorescent bulbs are not on the endangered spices list that I am aware of. Hell, we just replaced all the sodium lamps in several large work areas with high intensity fluorescent lamps. They went with T5HO lamps and the things are incredible. Anyway, standard lamps like you have should be fine. That is my guess anyway.

7/14/2012, no more T12 or T8 with 2 pin fluorescent light bulbs.

A 100W equv CFL bulb uses about 23W, has 12K hours est life and costs about 6 bucks.

...
incandescent bulb: 12000*100W= 1200KWHX.075= $90 + 12*.15= $91.80.
CFL bulb: 12000*23W= 276KWH*.075=$20.70+~$6~=20.70.
