2 MH in one reflector question

wrassie86 · 08/21/2006, 08:45 PM

is this a problem?I was thinking about running 250w 10k bulbs + adding 175w 20k bulbs mixed into the same spider light reflectors end to end.20k taking the place of my VHO. will there be a problem firing the 2nd set of halides a few hours later?
Ive read in some older threads that the first set running would make the 2nd set of bulbs to hot to fire.but i thought when flicking metal halides off when hot it was the ballast that needed time to cool not the bulbs.Can bulbs get to hot to fire with cool ballast?

I have the longer spider reflectors and my tank is 120g aga 4ft long.with the bulbs mounted end to end that would cover the entire space before the center brace.But also i think i would have color banding issues.Not sure tho
