Rajay, Slow down there little doggy. 
OK, here are some figures for you to ponder on:
We will use a 4100k rating for this purpose,
The Good ol VHO 110w lamps Produce aprox. 6000 lumens.
The T-5 HO which is 54 watts produces around 5000 lumens.
Just for fun, the t-8's which are not HO/VHO at 48" and 32watts produce about 2900 lumens.
Now, these figures are for non reflected(internal) bulbs running at the same color rendering of 82. This of course will be a bit different from different manufacturers.
The T-5's in general are not quite as bright as the VHO's but they are far more efficiant in watts per lumens. Watts=heat. Yes I have run them all before for compairson and I still like the MH over VHO and t-5 but watt for watt, you cant beat the t-5's. Now add parabolic reflectors into the equasions and you will have some nice lighting no matter which way you go. BTW, I no longer have the data sheets that were produced from these tests so dont ask I tested the t-5 about 9 years ago and I know they have improved since then. If you really want to have some fun, try using t-2's and t-3's. To bad they are not manufacturing the right colors yet for the public.
I still have both setups with VHO and T-5 and to be honest, if I were to choose one over the other, it would be the t-5 hooked up to an Icecap ballast.
