Re: black light wattage

i built one following specs here:
http://www.eepjon.com/ubldit.htm

cost about $400 CDN for materials, all told.

and am using the GE bulbs recommended (20 watt): works like a charm!

i only have to leave it on at first to get all the bulbs going (plus an
occassional tube wiggle since they have *never* all gone on at once for me)

5-10 minutes for cyano diginegs; same for salted paper; a little less
for VDB.

best of luck,
k

When I lived in Arizona I learned about cyanotype - (the old chemistry) and used sunshine (of course - smiles); and I have experimented with Polaroid techniques. Since so many of the alt processes produce a "look and feel" I relate to, it is time to try more...many more...Woah! On to the first step and my question.....

A few weeks ago I searched the archives for information about how to build one and found some helpful posts. What I didn't find was what wattage black-light bulbs folks consider to be the best for alternative processes. In my search of the web to find information about the types and sizes of bulbs available I found a variety of watts...mostly low (15 watts, etc.).
