250 or 400 watts?

[maimz]

anyone ever tried the sunmaster metal halides..i know they are the best for hydroponics...although this doesnt holdmuch meaning over here..they do have an amazing blue/white spectrum product that might be worth checking out..they are the number 1 in PAR watts so i urge you guys to check them out..from what i know about hydroponics the 250w are a waste of time and money as you can have the 400w for peanuts more....this would allow you to have the light higher from the tank and spread the light out more...btw..anyone have a line on sheets of hammertone for a reflector?
