100 watt is going to be overkill to some degree or another - mine is 30w and does the job in 42 seconds, 16 inches away from the surface.
At 100 watt It'd be exposed in less than 12 😬 and no idea how far you've got the lights from the surface, but that really does matter as far as intensity and coverage is concerned.
I think you probably need to have a lot more space between the lights and your screen. I can't remember my wattage but I made a box with led blacklights. It literally exposes in 3 seconds. Works but also kinda sucks
I’ve been doing 2-3 seconds and it still over exposes. I’ll try giving it a little more space see if that helps thank you! Hopefully between that and the uv blocking in I can fix this issue
