Sick of the MH heat thing really... but they do supply most of the heat for my house in winter. :mrgreen: I might yet go back to T5s, Hmmm... but I'd loose the ripple effect *sigh*

400 watt halides on 90 gallon tank in my basement- ran fan on high just above the sump - had to replace evaporated water every day - also had to be careful to have blinds drawn on the basement windows on the really hot days - still got temperature swings of 3 degrees on the really hot days.

Have run with Solaris PFO LED lights for almost a year... no chiller required, temperature fluctuation of 1 degree at most.

What was the T5 wattage vs the MH wattage that you are running now?
