Get a par meter. That's the only way. Nobody will ever be able to tell you what par readings you are going to have. Even if you have the same lights as them and same height of tank there are always factors that make every tank and situation different. Either get a par meter or use clues from your corals for help. If they are towards the brown side they might not be getting enough light. If they are fading they could be getting too much.

Where the heck did you find leds that aren't dimmable? That's really old school.

Lol got them from a reefing buddy who shut down his tank. Good lights grew lots of sps in his tank
