Despite the mispelung, I grokked your meaning. How about:
a bunch of light tubes,
fiber optic cables with lamps at the other end, or

LED lighting is probably the long-term solution; LED's work just
fine in cold environments, except for being expensive. They
are efficient (eg, Wind Cave's electrical bill dropped a lot:
) and "green" (eg, NPS and/or its Xanterra contractor have installed
a bunch of LED's in shops and visitor centers in Yellowstone and
Yosemite, and for the Liberty Bell:
For fluorescents, "Cold weather ballasts that can start the lamps at
temperatures below 0°F should be specified for applications where the
ambient temperature is expected to be below 50°F. Cold weather
electronic and magnetic ballasts can be specified for HO and VHO
lamps that can start them at temperatures as low as -20°F.", per
and also see <http://members.misty.com/don/f-lamp.html#sb2 .
The 750 watts of fluorescent lighting (with ordinary magnetic ballasts)
in my garage works ok at 20F; if it's much colder than that, I work
Neither do I. <g>
I think they'll handle most situations, though. I put one of the new
outdoors screw-ins in my porch light last fall, and it started just fine all
winter. But it doesn't get that cold here.
Pete, just went through this scenario with my shop (Eastern TN). I
settled on T-5 HO 6 tube fixtures, 54 watts ea, electronic ballast.
Electric supplier has them in his warehouse and said there is no
problem with instant start in zero degree temps.
Hope this helps.
It is not entirely true. The law basically mandates that bulbs which put
out light similar to current 40 watt through 100 watt have to be as
efficient as halogen bulbs are now. So for cold weather you can use halogen,
and in the very near future LED lamps will drop in price enough to be a
no-brainer. The law still allows exception for all sorts of decorative or
I've never had fluorescents fail to come on. The might be a bit slow, I'm using
technology with mag start ballasts and the larger tubes, I live near 45N in
occasionally get some cold weather from time to time.
Fwiw, waste heat isn't waste 6 months out of the year up here. Your mileage may
California where cooling is more of an HVAC issue.
If you want an extreme example of this -- wire up a PR-2
flashlight bulb (3V) to the 120 VAC line. You will get a very brief
bright flash, and the bulb will turn into a mirror -- silvered on the
inside by the evaporated filament.
I did this decades ago (about 1960 IIRC) and didn't have the
tools which I now have. It would be interesting to see an oscilloscope
trace of the flash, and to compare it to another identical filament, but
in a much larger enclosure, to see whether the coating starts dimming
the output before the filament totally dies.
It snows around here, but I've never seen a driving snow storm in
North Central Florida. :)
The LED traffic lights around here also generate so much RFI that AM
radio is useless. Any signal from the BCB to 30 MHz is either full of
noise from the switching power supplies, or below that noise floor.

It's easy to think outside the box, when you have a cutting torch.
