Tried them out did not like them for any price first for a 125 gal I needed 3 of them there was noticeable spaces of light in tank I paid $695 each online for $2100 I did not see the value I thought I was going to be blown away thank god I purchased them online because I sent them back after a week with no problems !! A lfs I would be stuck with them and it was not for my tank it was a friends tank !! But my recommendation any way he ended up going t5 and he's happy !! My tank I stuck with led because I love them I purchased the ecoray 120d for about $500 each I like them better u cant dim them like the radions but that's a non issue for me I like all on or just the blues and I believe in separate moonlights for $40 why keep a $500 or $700 fixture on for 24 hours straight I give my main lighting a break after 9pm
