New Light for 72g bowfron

[creekchub]

Hi everyone, I'm hoping to get some comments on a good light for my tank
(72g bowfront) I would like to get involved in some soft corals, nothing too difficult. My tank is 23" deep, also will these new (TS, HQI) lights cause a heat issue?
Do you guys use chillers?

go with either a 48" mh or t5 with individual reflectors. with t5. heating shouldnt be an issue at all. with mh, it shouldnt be a problem if u leave an open top and ur room temp is less than 75 degrees. i hv t5 over 72 bowfront, and dont use a chiller.
