Did you get an actual spec on the UV needed to cure (UV-A/B/C)?
Most stuff you can buy is UV-A/B (black lights, nail polish driers, etc.). UV-C is the stuff that many of the industrial products like finish and epoxies require, but the C is what can damage your eyes and quickly if exposed. Of course a lot of these will cure with A/B given a long enough exposure. I have several pond pump sterilizers that have UV-C sources, a lot of shielding and the bulbs are clear, some kind of arc lamps. The A/B I have are violet colored florescent.
Of you have an old first generation LED bulb, like the Phillips with the outer shell acting as the phosphorous layer that converts the LED's UV to visible, it is easy enough to remove that layer and have a bright hard-uv source.
