anyone using cheap metal halide bulbs from ebay? like coralvue, Hamilton, and no brand bulbs? what do you think about the quality or coral growth? I'm currently using pheonix 14k and would like to switch to 20k.
I use a 14K hamilton. Color is a lot like a 20K phoenix. Not a cheep bulb. I wouldn't use an e bay special. Not enough savings to take the risk. I am going to use my Hamilton 2 years.
