Twin Arc 10K AND 20K MH Bulb?!?!?

[zigzag1]

Anyone have a chance to try this or similar? I would be interested in your experience with it? Is this basically 2 175W bulbs in one envelope? Also, if you have used one please share what type of ballast you used. TIA!

i saw one of those at MAX.. it was pretty cool. It only lights up one at a time, so like while you're at work you can have the 10ks on to get growth, and then when you come home it switches to 20k for color
