the light intensity will be less with t5 compared to 250w mh. why do u want to switch may i ask? if its the colors, u can always change the mh to a higher k bulbs. t5 is good imo, bc i hv it. t5 produces less heat.

Yes, you will have no problem keeping SPS with a T5ho.
If you used good bulbs on the TEK and attached some fans to it then it might work well. My first choice would be the Aquactinics 48" Constellation or Solarflare. I wouldn't doubt that the Solarflare would actually give you more light than the halides.
