Photofloods (do you get those in the States?) are the

a very short life -- a couple of hours for some of them.
I don't know I live in Canada. :)
I suspect photofloods do that. Oddly I have found regular incandesant
bulbs out
that contain neodymium in the glass to filter out the yellows and give a
higher color
temp much like daylight. If you need real daylight the color temp is
only one aspect
of daylight. The other factor is how close the spectrum of light
matches the daylight
sun. For real daylight
Company #1 claiming they have the best.

Company #2 with the same claim but with 12v lighting.

I don't know how they compare with other products elsewhere in the world
but they
both look to have a product that looks to live up to the 'daylight'
claim and you can afford.
