OK so today I received my Coralife Aqualight Pro 48" unit. It's the 150 watt MH unit. Anyways one of the blubs looked perfect out of the box. The other bulb though had a rusty brown look to it. After hooking everything u I turned it on to make sure everything was working. I let the unit run for about 15 mins and noticed the the light in question wasn't putting out the same light as the one that looked good out of the box. The one in question had a yellow look to it rather then the blueish white look that the other light was putting out. After turning the unit off the blub that looked good cooled down pretty quick but the other one took a little longer to cool off, and seemed to be putting out twice as much heat when it was on. Well after turning them off and letting them cool I noticed that the good bulb was clear as can be, but the one in question turned from the rusty brown color to a milky whit color. \r\n\r\nSo my question is do you think that the bulb is just bad or is it the unit. I emailed the company that I bought it through to see if they would replace the bulb for me. It appeared to me that the good light was probably brand spanking new but the light in question may have been ran during testing at the factory and be ready for replacement already. What do you guys think. Has anybody experienced this before with any of your MH's.
