Runs Cool. No difference in PAR from m81 By Brads_Reef on 4/30/2015Brads_Reef would recommend this product to a friendI Just recieved my replacement ballast. Was able to take a par meter to test if there would be a reduction in par from the the hamilton m81 ballast and there is not. I am really happy with my purchase! Super light. Runs cool.
