Write them an email my friend. Sorry for the delay. They will tell you the techical data.

hey bro I had a couple questions on those northstars. I currently use AAw's I only like bare bulb hoods. How well does the northstar cover a 4x8 area. I couldnt find dimensions on the reflector they are all in another language lol

I read your post to JACKMAYOFFER on that Metrop and aptus lineup and im going to rock a 30x50 greenhouse medical grow in 150gal smart pots...I ordered the Metrop from holland already and waiting on a package price for the aptus line...do you have any pointers for a guy about to take the leap of faith?hehe
