Does frequent rebooting harm a computer?

Compact fluorescents are less efficient than full sized
fluorescents and "one" 13W CF is not enough to light up a
room to the level most anyone not accustomed to living in a
cave, will want. You'd have to contrast a larger number of
CF to smaller # of full sized fluorescents.

True. However, vs 60w bulbs, they're much more efficient and provide
roughly the same amount of light.

And yes, I'm believing the marketing babble here, although I did do a
little experiment when I first got them, I didn't tell anybody which
rooms had the new bulbs and which ones had the old ones, and neither my
girlfriend nor my roommate could tell.

True, plus the actual wear from repeatedly cycling, the cost
of replacement ballast (or whole CF "bulb"), as well as the
energy to produce, distribute and sell the product.

Sure, but all of which simply serve to shorten the life span of the bulb
(I'm calling the entire assembly the "bulb")

So, lets do some math, k? I'm currently paying $0.059666/kWh. Now
lets say I'm comparing a 60W incandescent bulb with a 13W compact
fluorescent. I've already established that they're equivalent for my
purposes in terms of function, so the consideration is price:

Cost of purchasing a 60w incandescent bulb: $0.3725/unit.
Cost of purchasing a 13 compact fluorescent: $5/unit

I'm paying $0.059666/kWh here, your results my vary.

Cost of operating a 60w incandescent bulb: $0.08591904/day
Cost of operating a 13w compact fluorescent: $0.01861579/day

Given that the cost difference is $4.6275/unit, we can work out that it
takes 1,650 hours for the compact fluorescent to become more energy
efficient then the incandescent bulb to operate. For those playing the
home game, that's just under 69 days.

If anybody wants to verify my math, please do, and if I've screwed up,
please tell me:

This one is easier to understand:
http://www.google.ca/search?q=($5-$0.3725)+/+($0.08591904/day+-+$0.01861579/day)+in+days

This one uses all the original wattage and $ figures, so you can enter
your local costs for bulbs, energy, as well as your choice of wattages:
http://www.google.ca/search?q=($5-$0.3725)+/+(($0.059666/kWh)+*+(60W-13W))+in+days

While regular incandescent bulbs last usually between 750 to 1,000 hours
before burning out, some long-life bulbs last up to 2,500 hours. Yay.
Compact fluorescent bulbs, on the other hand, will run over 10,000
hours, so that's roughly 10x the length.

So lets do some more math... Cost of operating bulbs to 10,000 hours?

To run the 60w incandescent bulb 10,000 hours it would cost $35.7996. To
run the 13w compact fluorescent it would cost $7.75658.

To purchase enough 60w bulbs to last 10,000 hours it would cost $3.73.
To purchase enough 13w compact fluorescent bulbs for the same period, $5

So a bit more math, and even considering the purchase price, each 13w
compact fluorescent bulb saves me $29.32/415days, or $25.70/year.

I'm sure that going to full fluorescents would be cheaper, however there
is also a significant cost factor in installing the fixtures in the
first place, and since I seem to be moving around a lot these days I
won't outlast the cost savings even if they used no power (in other
words, vs power costs for the number of 13W compact fluorescent bulbs
I'm currently using, I won't even break even for the installation costs
of going to full size fluorescent fixtures)

roughly the same amount of light.

Yes, completely true. They're also very handy for recessed
lighting like a desk lamp I have here that went through a
regular every 2-3 months (atypically short life due to
trapping heat in the reflector cavity) has ran same CF for
over 2 years thus far.

And yes, I'm believing the marketing babble here, although I did do a
little experiment when I first got them, I didn't tell anybody which
rooms had the new bulbs and which ones had the old ones, and neither my
girlfriend nor my roommate could tell.

It is rather hard to discriminate small differences in
brightness unless an A/B test is set up. Mostly the
difference I notice is that the CF seldom have a good cast,
it's always a bit too yellowish. It is harder to notice
from a room as one's eye easily adjust but quite apparent
when comparing photographs taken under this lighting.

Sure, but all of which simply serve to shorten the life span of the bulb
(I'm calling the entire assembly the "bulb")

fluorescent. I've already established that they're equivalent for my
purposes in terms of function, so the consideration is price:

Why are we doing the math?
I never argued that incandescents were the issue here. My
argument was about using several CF vs far fewer full-sized
fluorescents, that what I had written applied to using CF.

I'm sure that going to full fluorescents would be cheaper, however there
is also a significant cost factor in installing the fixtures in the
first place, and since I seem to be moving around a lot these days I
won't outlast the cost savings even if they used no power (in other
words, vs power costs for the number of 13W compact fluorescent bulbs
I'm currently using, I won't even break even for the installation costs

I suppose installation costs could be an issue but "moving
around" in itself can be expensive and time consuming so it
may offset that. Clearly either is better in the long term
than incandescents.

But I can take compact fluorescents with me, so it's a significant
consideration when comparing the compact vs fullsize fluorescents.

I've got over $500 worth of compact fluorescents in the house right now,
all of which came with me from the last time I moved, and some of those
were from my apartment (so they're now 2.5 years old and have survived 2
moves), and I've yet to have one die.
