I use Sylvania F40 350 BL tubes. These are 4 ft standard output tubes.
The shorter the tube the lower the wattage.

Compare tube costs. I found that these were the cheapest tubes. Longer
or shorter tubes cost more. I made a 2' by 4' printer , uses 10 tubes,
larger than what I currently need, but building something smaller would
have been more expensive.

Shop around for tubes. If I remember correctly Rick bought GE tubes from
a different supplier in Saskatoon that were around 25% cheaper than what I
paid for mine.

The tubes are often the most expensive part of a flourescent UV printer.

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.).
