yeah but its still just 600w bulb at 12-24 inches away.i have multiple 600w lamps running,some as close as 15 inches apart and my tops get as close as 5 or 6 inches from the lamps at times.it just wont bleach as bad as a 1000w no matter how many you stack side by side lol.it sounds like a great idea to make a complete spectrum in one fixture but i just dont agree you will need high ceilings to run them.ill use these pics only because alot of my lights are on movers,but these are not .both these plants have at least 1 x 600 hps and 1 x 600mh bulb right above and actually they are both within 3 feet of a pair of
gavita 6/750de set at 800w
first one is a chemcookie,cookies love bright lights lol
and this is some kind of damn landrace afgan #1 been in there almost 9 weeks with no signs of light bleaching
now if your talkin about a 1000w de hps and a 1000w de mh in one hood,yeah you would need more than 8.5 feet of ceiling height prolly unless you grow 2 foot high plants lol. 600w just aint got the same bleaching power that 1000w do.you be ahight :)
