Any ideas what a 12,000 Kelvin metal halide bulb will do? I'm looking for bulbs in the 250-400 watt range in a t15 configuation (tube) and i can't find any at 5000 K so any thoughts what the 12K Kelvin bulb will look like?
A 12k bulb will be extremely blueish. I would not reccomend it since it will not be a watchable image.
halide bulbs
have what can only be described as "wonky" spectral distributions, perfectly predictable, but not eye-pleasing. I know from photographing church interiors where halide are often mixed with incandescent or fluorescent, and there 's always some pesky daylight!

allternative to HID?
I came across these today, I'm looking at allternatives to HID lighting for my PJ. I've considered the LED route but dont want the hassle of "clustering" a couple thousand REALLY expensive LED's.
Then I found these http://www.sunstreamer.com/index.htm if they can be run on a regular Flouro ballast then all that is special is the tube. Granted at 2feet long/tube it would mean a PJ box of probably 26 inchs or so square...but the distance to the LCD panel could concieveably be quite close (still with some fan venting and an insulating sheet of glass (low E?) I think).
The "end mounts" for a flourescent tube are available in many config's so they could be custom mounted allowing for VERY close together spacing of the tubes (thinking ohh maybe 12 or 14 tubes?).
Any thoughts?
if your not livin on the edge...you're takin up too much space!

zardoz,

If you want to have a look you will see that there are more than 5 or 6 threads. The threads that I posted to were directly related to light sources and heat issues related to light sources. I felt that possibly there was value in this idea and members that were looking for "specific" answers to their concerns might not be surfing the forum for new threads.
So thanks for the "critique" of my posting habits, but do you have any opinion on the topic at hand?
