talking about T5 and SPS color !

OK I don't really see the difference in power between these T5 tanks and a MH tank.
The first tank is 350g and tank dims (converted) are 6.5' long x 36 D x 24H.
For lighting its using:
10 x ATI Aquablue special 80 Watt which equals 800 watts
4 x ATI Blue plus 80 Watt which equals 320 watts
6 x ATI Aquablue special 39 Watt which equals 234 watts
2 x ATI Blue plus 39 Watt which equals 78 watts
Thats a grand total of 1432 watts over that tank.

Second tank is 250g and tank dims are 6.5" L x 36 D x 28 H.
12 x 80 Watt ATI Powermodul which is a total of 960 watts.

I think the main advantage the T5s have over MH is the even distribution of light throughout the tank.
