German, it made in Holland ya spaz, lol.....The Germans make everything, at least let the Dutch feel good about their grow technology, lmao.
They do look good, but I like where he said, HPS is for quantity, and this is for quality. But if you use it in combination with the HPS then it is the BEST! Ok, the electronics part is more effecient (if you are running 30,000 light units and growing toms for Europe) But with one in a cabinet or cupboard, a 1-2% increase is not massive.
So basically, run an HPS with a bulb giving you 65k spectrum and you'll be hitting the golden spot anyway. Remember peeps, the sun is in the sky, but so are clouds, and plants don't always get 100% direct sunlight booyakad in their faces all day long. So do not worry, you'll be fine with a simple HPS in the mean time, lol.
