I use an 80 watt LED light thats similar and I expose at 20-25 seconds. I use an exposure calculator to nail down my time, you should look into getting one.
You won’t learn anything asking ppl about exposure times bro I learned that the hard way. You could literally have the exact same setup as someone else and have completely diff exposure times due to environment and other factors. You should buy a 21 step test thing it’ll save you so much time and money. Or use one of those free emulsion tests. I just find the 21 step one so much easier but yea try and dial it in yourself
It depends on what type of emulsion you're using. It could be 15 seconds could be 9 minutes. And that's if this light is worth a shit as well. Find some videos and maybe if you use the same emulsion as some documented examples have, you could get a ballpark exposure time. Until then test, experiment, and good luck.
Here’s an [exposure calculator](https://www.anthemprintingsf.com/Screen-Exposure-Calculator-s/216.htm) with instructions how to set it up. Go to the website of your emulsion and they short have times set up by light source as a starting point. To fine tune it down is just doing it
The emulsion you are using is way more important than the light source. I've used 2 at my home and one took 44 seconds, the one I use now takes 11 seconds. Huge difference. I have this exact light, I love it, but you need to ask your emulsion manufacturer not us.

my 50W UV LED (and emulsion, lens, glass, distance, humidity, moon phase...) lets me expose ~40s with my go-to coating method.
What emulsion are you using?
German hobby stuff: siebdruck-versand.de FLX SCREEN Hybrid-Fotoemulsion (One-Pot/Allround)
I use Ulano Orange or Ulano GTX. That might be why you’re longer on your exposure times. I got mine dialed in at 22 seconds.

Time could definitely vary I use a flood black light with the frosted glass 1min 14 burn time
