I was curious if 250w MHs are cooler than 400w's. I would assume so, but I was just curious from people that have used them. Thanks a lot

yes... a watt is a watt.

500 watts of LED put out more heat than 250 MH.

Yes, a 400 watt hung 19" above the water heats my tank more than a 250 watt hung 13" above the tank. This is a lumenbright mini-wide.
