Uv bulbs recommendation needed!

[SLVRGLTN]

Ok I have seen a few post but I'm in need of specific info regarding UV bulbs for the following processes Carbon,Pt/Pd,Salt Prints & Cyanotypes, these are the processes I will be trying over the winter I have a UV LIGHTSOURCE that takes 18" fluorescent bulbs 15w so should I use the BL? BLB?SA or others for those processes? Any info would be greatly appreciated.


Thanks Brian

Brian,

I think Sandy King prepared a document on UV light sources for alternate photo processes, that I found on through a Google search.

You might also look at the "Alternative Processes" section on APUG (see: www.APUG.org) , or Advanced Processes and Carbon Board at: http://bostick-sullivan.invisionzone.com/index.php .

hope that helps,

Len

The SA bulbs are not good for some processes. BLB and BL both work, but BL print somewhat faster.

Here's the link to Sandy's article on UV light sources: LINK (http://unblinkingeye.com/Articles/Light/light.html)

One note on the article: the underlined text are links ... the ones linking from the BL and BLB bulbs show the spectral power distribution of the different bulbs.
