I am looking for input on good blacklight to inspect silicon coating coverage on PCB's. This inspection is visual. Any advice or recommendations on lamps or bulbs?

Hey all, we will be starting to coat our PCB's soon. I am looking for info on what type of UV light is needed to inspect the boards. We will be using Humiseal 1B73 Acrylic coating. TIA, JD
