| Re: 175 halide retro for sale or trade. It is just a retro. It will cover about a 30 inch long area, but the bulb is like 8 or 10 inches long. I'm running one on my 30 long and one on my 29 gal and they light up both tank great. The 30 long is 36 inches and I've been running a single 175 watt halide for about a year on it. |
