I have (3) Metal Halide Fixtures (MH) w/ balasts. They are adjustable from 250W-400W. I have had these for 1.5 years and they were over my 220 gallon mixed reef tank. The bulbs are six months old and are radium 20k. I am asking 300$ for all three. I can get better pictures upon request, just seeing if there are any takers out there.
