I took a gander at the Mars lights. Interesting. I see there is also a 600 watt unit.

I guess it all depends on your ultimate goals.

I still like using the T8s as a ready made heat mat! I just stack my flats ON TOP of the T8s and utilize the fact that they emit a healthy dose of warmth.

Cover the shelving unit with plastic, and voila', instant germination chamber. I measured the soil temp right at 82 degrees!
