Twon why don't you keep the 400w fixture in the front and put a 250w hqi in the back, then later sell the 400w and get another 250w and run them side by side. I don't think that your house ac can keep up with the heat of you mh in the summer and you will have to get a chiller anyhow there is a guy on craigslist selling a hqi system for $200 go for it!!

yea i saw the ones on craigslist and that is why i have considered the 2 250w. can hamilton ballast run any 250w bulbs or would i be limited in bulb selection?

that also brings up heating issues for me. in the past i had heating issues, had my tank runing at 86 degrees at times in the summer. chiller wasnt really an option because i lack the space for it (tank is in my living room) so then i went and bought a home central air conditioner unit. it has helped lots but im still running at 80 degrees unless i crank up my aircon and put sweaters on me and my family lol i made sure my aircon was slightly oversized for my home. or maybe i can get someone to fabricate eggcrates made from some sort of corrosion resistant metal or heat resistant plastic thats strong enough to hold my lighting and use that rather than my glass tops.

yes i would prefer a 400 over a 250 also but how about two 250 over a 400? if kept in close proximity like only 2-5 inches apart between pendants and having both the lighting overlap i am hoping that it would atleast be close or = to the 400 in par and intensity. i would have more flexability with two 250. i would not have a huge reflector sitting on my canopy and with two hqi i can get small pendants or just the shell to fit it into my canopy just need to find a way to rid the glass top to let the heat escape.

what do you guys think?

with 2 250s... .you will get alot more lighting out of it ... and there is a central over lap ... so the center is alittle bit brighter then the outsides... but now you will also have lights on the sides where you dont have much light now..... as for the glass top ... i think we can rig something up
