Which to choose.... T'5 or HQI?

[Shadow]

I have a 29 gallon nano and am looking to upgrade the lighting. Any thoughts about which to go with? the T-5's or the HQI? i know the HQI gives off more heat, but do the T-5's give off the same light as the MH's?

I have softies and LPS in there right now but would like to brighten up the tank and give my zoos more colour and later on have some SPS.

I was going to go out and buy 2 Viper T2 70watt HQI units today but i thought i would do some more research first.

Is 250 watt overkill? or is 150 watt ok? with T-5's they only add up to 96 watts...

Any input would be appreciated.
