[Alt-photo] Re: UV light box

[Bob Cornelis]

Thanks for the response, Charles. 

I went ahead and ordered 7 of these bulbs (sort of on a deadline to build this box), thinking I’d put them at least 4 inches apart giving me a coverage area of 24x28. I’ve heard these bulbs have a good, even “spread” so I’m hoping the 4 inch spacing is fine. I guess I can always buy more of them! 

Other opinions welcome!

Bob

I can print 11 x 14 with this and can't see the need of anything larger.  I have used a unit at Southern Oregon University which had 4 ft tubes spaced about 6 inches apart and at least 8, probaby 10 or more inches from the paper. It worked well. It was open on three sides so many students could insert their projects at one time and could remove them without disturbing other's.
