RLaForce Posted November 10, 2009 Share Posted November 10, 2009 Ok so I need to get replacement bulbs for a 250 watt double ended hqi. I would like to go around 14 to 15k for this. Reason being I want better growth rate and color to pop a little more in my tank. I have been reading on all the different pars on different bulbs. I think I have narrowed it down to Phoenix or Giesemann. I would like opinions on what people think of both types, or if you think a different bulb could do a better job for what I want. One of the big draws for the Phoenix bulb is looking at the studies they don't need to be replaced as often. My lighting is on yo-yo's so I can move the light closer to the water accordingly. Thanks for you advice!(scratch) Quote Link to comment Share on other sites More sharing options...
