Same for us and bravo to you. Howard Tanger

And, last but not least, remember that all eco friendly bulbs are mercury vapor based. The mercury vapor produce a huge amount of ultra violet light which is converted to visible light by a fluorecent powder inside the tube. The mercury vapor is a nasty and toxic stuff we are unable to recycle as are the rare earth powders coated inside the tube. This will ensure backyard pollution for the next generation and an enormeous increase in mercury gas into the atmosphere... Eco friendly you said ?
OleOh well.
If worst comes to worst, I'm sure I could rig up some kind of shutter contraption inside the lamp housing on the Durst 138S. Or put the enlarger lens in a shutter.
Then just leave the lamp to warm up, open the shutter to expose, and shut it at the end of exposure.
Since a low-energy bulb produces less heat than an incandescent bulb with the same light output, it might even be better!
Can you imagine going into a walk in closet and turning on the light so you can find your clothing. But wait, I `ll have to stand there 5 minutes while the thing warms up. The alturnative is to just leave it on the time and thereby defeat the whole purpose. Then we get into the mercury. We can`t have mercury batteries anymore, but mercury light bulbs are just great.
Politicians amaze me. They all think just by passing a law they can defeat science.
We got it going with alcohol in gasoline. Half the energy content as gas so you get poor mileage and then you need to add the oil used to make the alcohol and grow the crops and it is a net loss.
They should be banned from passing laws.
You didn't forget the mercury released by coal power plants, did you? Also, CFLs do not take 5 minutes to warm up.Can you imagine going into a walk in closet and turning on the light so you can find your clothing.

Hello !
I heard today that in France, global cosumption for lighting is only 1% of total energy consuption.
So some of the Green people ask first to make savings in heating (about 25 to 30 % global if I heard correctly) transportation, fridge and freezer (a big percentage on home uses) before reducting the marginal 1% onthe bulbs...
They also said that we SHOULD use a switch to turn off the TV set, satellite decoders and the like staying ON in standby. The guy said that going from CRT to LCD or plasma TV was a disater because of the huge consumption difference with a comparable CRT device....
I think, this time we will see again the mercury cell ban.... Even Green people said that it was not so good an idea.
Georges:
One of the (few) things that I remember from engineering school was the quotation by Lord Kelvin -
"I often say that when you can measure what you are speaking about, and express it in numbers, you know something about it: but when you cannot express it in numbers, your knowledge is of a meager and unsatisfactory kind; it may be the beginning of knowledge, but you have scarcely, in your thoughts, advanced to the stage of a science, whatever the matter may be."
Your observation is very correct - many of the things that environmentalists (or representatives from any other special interest group) advocate fail to make any sense at all when you take the time to examine them in careful detail. They are intended to appeal to the emotions rather than to logic.
One example. We are told to replace incandescent lamps with CFLs, and to unplug our cell phone chargers when they are not actually being used to charge the phone. I'm an engineer, and I put number on things. And when I put numbers on the first of those recommendations, I fine that the higher economy of a 27w. CFL offsets its cost premium over a 100w incandescent lamp (both producing about 1500 lumens of light) at the prevailing cost of electricity in our area after 300 hours of operation. And based on that analysis, all of the lamps in our home that operate more than 300 hours per year are now CFL.
But the transformer that charges my cell phone is rated 6 watts. And assuming that it is a fairly inefficient design, the no load losses should be about 1%. At the same energy cost rate used in the CFL analysis, that cell phone charger is consuming about US$0.08 of electricity per year.
So I can accept the CFL argument because the numbers make sense. But that amount of energy wasted because my cell phone charger remains plugged in continuously is microscopic by comparison.
The point - let's deal with facts and not emotional exaggeration.
It does seem that provision of simply on/off switches on many devices would not be difficult or expensive to provide and would then at least give the consumer the choice (other than unplugging the TV from the wall etc.) of elimintating a phantom load should she/he want to do so.
Which is exactly what most equipment was fitted with before remote control took over.
I think it would be good to have this fitted again.
In the UK, most of our mains sockets are fitted with switches. Am I correct in thinking that the US socket is not switched?

I belive in Europe too only UK have mains socket with swiches...
Well, if you want switches for yours gadgets, and you dont know to install swich on power cord of your gadget, use extension cord with preinstalled swich. For 1 or 2 EUROS it is not expancive. I do that
I do that with my computer too. And I think power unit of computer don't like that, I had to but new one after 6 months...![]()
