Im looking at getting some new lights and Ive stubled across the Hamilton Cayman sun reflector w/moonlights. Im looking at the 400watt version of this unit (because i havent found a complete light unti that has 2x400watt MH with t5 actinics and moonlights) and it seems they only offer the 400 watt pendant in the HQI version and thats the only MH bulbs any of my fixtures have had. Is this a good reflector(think i would buy Lumatek ballasts to go with it) But the bigger question is about the 400watt double ended bulbs. I was wanting to see what selection of bulbs i could find for these fixtures and the only brand i can find is Hamilton 400watt double ended bulbs. I've never used that brand of bulbs (currently running phoenix 250w HQI in my old fixture that needs to be replaced) so I dont even know if they are good. If i buy this fixture am i going to be limited to only using the hamilton bulbs....please tell me there are more brands that make a 400W double ended bulb.
