| I still think that 400w Mogul based bulbs are unnecessary. Sanjay himself has said that he would have gone w/ 250 watt HQI DE's if he didnt have the money tied up in a newer 400 watt set up. He's found that you get essentially 5/6 ths of the PAR values, for something like 2/3rds of the energy usage. (I know, I know...fractions suck.....carry the one...etc). I'm definately interested in the studies that are gonna be done on the 400 watt HQI DE's though...that might be really nice for a deeper tank.
Now that we've completely hijacked this thread.......
