Here’s a note to the would-be overdrivers of ReefLux lamps: If you are overdriving ReefLux metal halide lamps to get some crazy good PAR numbers, don’t. The lamp above may have been overdriven for more than 12 months but we would hope that when metal halide lamps fail, they would do so without splitting the outer envelope which shields your reef inhabitants from copious amounts of deadly UVC light. As you can imagine, of course the lamp above did it’s trick over a large Acropora colony which subsequently bleached and died but hey, you gotta pay to play right? In all fairness, this kind of failure could have happened to any lamp which was used for over a year under conditions for which it wasn’t designed.

Gotta love high standards of quality control
I hate to say this, but I had the exact same thing happen to two ReefLux bulbs that were less than 4 months old. The bulbs I was using were on a standard magnetic ballast and not being overdriven like other ballasts out there do. Thankfully for me, I was using a cover between the bulbs and tank.
