since you are lifting them the PAR values are going to drop in the tank and you are also thinking of dropping down to 250's . 250 watt is not always a down grade from 400's but with the ballasts you are looking at ya they are. so now you are lowering your PAR even more.

I recomend that you stay with 400's if you want 3, or go to 4 MH if your dropping to 250's on an electronic ballast.

I would personaly go with 4 bulbs either way, but I also like lots of PAR.

I agree. 3 bulbs/400W 4 bulbs/400W or 250W
