Where can I get white worklight bulbs?

The worklights I bought take 250w short double ended halogen bulbs. The stock lights are giving me this yellowish look which I would like to get a white look to it.

What light temp should I go with? (shooting outside at night time. going for moon like glow)

Where can I buy them? (I looked for the past half hour online and couldn`t come across any. HD just sales the stock yellowish replacements.)

Heres a chart I found online

You can get 3200K lamps at most pro-video stores that have a lighting section. That's as white as you can get without putting a blue gel on them.
 
I don't know quite what you mean, it really doesn't matter what the light looks like to you, if you keep the lighting at a consistent temperature it will all look "white" if you balance to it. Now if you want light that is consistent to tungsten I know you can buy 3200k bulbs for worklights. If you want light that looks "white" to your eyes then you probably mean daylight corrected. The only way to get daylight corrected is to use something like Compact Fluorescents or use blue gels.
 
I am wondering the same question. I thought I found an article online that listed a link to a store that sold daylight adjusted (blue) bulbs for 500w work lights. Does anyone know of a good place online that sells these lights?
 
Tungsten lights that operate at daylight (5600k) are expensive, hot, and have a super-short life, they are mostly reserved for still photography use.

What you want is standard bulbs and gels to change the color to 5600k.
You can use Lee's sweet-as-hell mired shift calculator to figure out what gel(s) you'll need to shift from any color temp to any color temp.

If the lamp is 3200k, you want a full CTB. If it's 3000, technically you want a full CTB plus an 1/8 CTB, although you may be happy enough with just the full CTB.

Maybe these are 3400K lamps that have a blue filter built into the glass?

The color temperature of a tungsten lamp is very close to the actual temperature of the filament, and tungsten melts at 3680 K. That's why 3400K is the practical limiit for tungsten. Above that, the filament gets too soft to hold together.
 
I guess blue gels would be the best bet, I wonder how i can hang them on in a way they wont melt, maybe a coat hanger or somthing like that. Or a seperate stand infront of the lights holding the gels up. Dam these worklights get hot.
 
Its amazing how the life of these type bulbs can go from 2000 hours in the 2700K range to 200 hours at 3200K. It is the case that the higher you go the quicker they burn up.
 
I was going to say that I bet those 250's are closer to 2800K than 3200. You can force your WB, but if you are mixing work lights with real studio globed fixtures, you will have to knock something up or down.

I'd start with some 1/8 CTB on the work lights and see if that makes your life better. Have a bit of 1/4 CTB in the wings in case you don't like the resulting preset WB results.
