1  IMAGE REPRODUCTION TECHNIQUES / Screen Printing: Discussion and Questions / Photo Emulsion Lightbulb on: January 04, 2008 11:21:07 PM
I had a few questions concerning the light bulb I purchased to try the photo emulsion method of silk screening.

I got a Speedball Silk screening kit for Christmas, and it recommended a BBA No. 1 Photoflood... which doesn't make much sense to me, but I assumed it was a 250W Photo bulb.

So, I purchased a General Electric 250W 4800 Kelvin Photoflood Lightbulb.  I was told by the gentleman at McBain Camera that this is the coolest burning photoflood that they sell.  However, the light bulb is blue, and I was wondering if that will affect the exposure time at all?

The caution on the back of the lightbulb also scared me, it states that I should keep myself, and all articles at least 4 feet away from the lightbulb whenever it's turned on.  But my kit tells me to hang the light 1-2 feet above my screen.  Do all photoflood bulbs have warnings like this?

Thank you in advance for any advise you can lend me.  Smiley
