I just noticed that a few companies are selling 1000w DE CMH bulbs (and fixture combos). If anyone has any experience with these yet, I'd love to hear about it. I'm not interested in speculation, hear-say, rumors, etc. The Growers Choice links to their 1000w DE CMH has an interesting notice about using them with HF ballasts, noting that they're developing a LF ballast for their higher wattage DE CMH bulbs. Here are a few examples.... Growers Choice Growers Choice Horticultural Lighting 1000/945/630w DE CMH Complete Fixture Grower's Choice 1000W Double Ended CMH All in One Fixture with Bulb
I'm using the Revolution DEva 1000, this unit will run the new 1000 CMH bulb, after this bulb is done I will try one. If interested, here is a post of this light system. Revolution DEva 1000w
