I have 2 used 48" ReefBrites removed from a tank I set up. They are both a little over 2 years old. One is Royal Blue, and one is a 50/50 White and Royal Blue. Now, both power supplies had become problematic and do not function 100%. The bars are fine and work, as seen in the picture with a new power supply. I'm keeping the power supply for the remaining bar on the tank. Power supplies can be purchased as ReefBrite brand for $41.89 from places like Premium Aquatics or as generic power supplies on ebay for less then $20, if your cool with no spending the extra $20 on the ReefBrite sticker. The power supplies are 24v 2.5a, fairly common. Looking for $85 plus shipping each. Shipping is going to run about $20, please buy both and save me some hassle! Paypal only
