Florescent light bulbs?

kelvins are not degrees.

not millihertz.!

Actually, what I SHOULD have said is:

It doesn't matter how cheap the gas is, the heat you get from a light bulb is FREE because you're paying for the light, not the heat.

That makes the heat actually CHEAPER than free since you have to buy less gas.

Are you aware of just how HOT the Antarctic is compared to 0 deg Kelvin?

hmm, how to get gas into a fuel cell...

. Don't know why but this word 'FLUORESCENT' must be one of the most misspelled. And the various 'spell checkers' know it!

The most common misspelling is "Flourescent".

I don't know how anybody can jump to the conclusion that there is a conspiracy to keep certain bulbs off the market! No evidence is presented here.

Also; assuming that 'Fluorescent bulbs' here means those that either screw or plug in, as direct replacement for conventional incandescent types, apparently there is definitely a significant energy saving. But on whether they are worth while from an overall 'economic' point of view 'The jury still seems to be out'?

The cheap ones are not reliable they either fail long before their stated life or fall apart or don't work very well in the low temperatures that area fact of life for much of North America and parts of Europe.

We can buy either conventional incandescents or fluorescent bulbs almost anywhere!

Currently one can buy four cheap bulbs in a package (4, 60, 100 watt etc.) for anywhere from 88 cents to around a dollar Canadian. Plus sales tax that works out to about 22 cents US or roughly 15 UK pence. They last a reasonable time and if not left on for long periods don't use much energy. Since we use electricity for heating anything then bulbs 'waste; contributes to our heating.

Yes, incandescents do provide some heating, but they provide it summer and winter whether you need it or not; and they most probably dump the heat in the wrong places. You want heating, you should put your electricity through a heater.

Over the expected lifetime of an incandescent bulb, the cost of the bulb is insignificant compared to the cost of the energy it uses. True, this is not the case for fluoresents, but the saving is still significant.

There are places where an incandescent is more useful - inside cupboards, on dimmer switches, and some PIR triggered systems, but for main room lights you should be confident of saving at least $10 US per year for each fluorescent bulb you buy.

CoreyWhite is just trolling.

Heh. According to the packet it came in, I'm currently using a 'flouride' toothbrush'.

BOOM! Quite efficiently, but all the light shines at the same time.

Light and heat and improved ventilation

Not 20% of _total_ energy distributed.

It is a fact of human consumption that, if a resource is not used in one place, it will be used in another place. There is no savings (I'm getting really tired of hearing that word) but a redistribution.

Now, at the consumer end, there is and incentive to reduce power usage; the bills are lower and they can spend money on something else...like a 20'x20' HDTV.

In my shop, our CPUs ran so hot we had to air condition the room even in winter.

Yep.

Yeah, _I_ am. "They" aren't. ;-)

There are methane fuel cells, but what does a fuel cell have to do with lighting? Make electricity, and run CFLs?

Haven't you ever seen a gas light? ;-)

"In this year, 1817, at the three stations belonging to the Chartered Gas Company, 25 chaldron (24 m³) of coal were daily carbonized, producing 300,000 cubic feet (8,500 m³) of gas, which was equal to the supply of 75,000 Argand lamps, each yielding the light of six candles. At the City Gas Works, in Dorset-street, Black-friars, the quantity of coal daily carbonized amounted to, three chaldron, which afforded a quantity of gas adequate to the supply of 1,500 Argand lamps; so that twenty-eight chaldron of coal were daily carbonized at that time, and 76,500 lights supplied by those two companies only." ---

So, does anybody wanna do the arithmetic on how much light you get per BTU of gas vs. electricity? ;-)

I suppose we should count the fuel for the electric plant and for the refinery here. ;-)

Cheers! Rich

Nah - if you learn to light one properly, the deflagration front is contained within millimeters of the mantle. ;-)

I have an office like that: 9'4" x 9'6", 8-foot ceiling, and I leave all 4 computers running, and even if it gets down to the 40's, when I come in in the morning, it's always nice and cozy-warm. If it gets too warm, I just open the door - it opens out onto an unheated factory.

Speaking of fluorescent lights, just a couple of months ago they got a guy to redo my ceiling light (which is obnoxiously bright, but there's not much I can do about it), and the guy refurbished this 8-foot fixture with iron ballast; he took the ballast and even the socket thingies out, and installed new socket thingies and electronic ballasts, and essentially turned the 8' fixture into two 4' fixtures end-to-end. He also gave me one of those screw-in fluorescents for my desk lamp.

Since the PHB is so cheap, I'm ass-u-me-ing that he's expecting a significant savings on lighting. :-)

Cheers! Rich

I have, maybe it's cheaper to buuild them for 240V operation. Or maybe it's a socialist plot!
