I heard from somewhere that a "blacklight tube" will do it well.

Extremely high wavelength is not recommended, as the photoresist cannot respond in that level.

But remember, this is a theory from someone else, so I would like to hear opinions from others as well.

from what I have read it is 350-420 nm broadband source for the dry film and liquid resists that you would probably buy for home use.

And....on the commercial side I've used sources in this range to create features down to 50 microns...but you won't do that with UV tubes...
