Bought two rl90 used, they have been used for about 14 months in another tank before I bought them. After two months of use with me I decided to pop off the lid of one lamp dident spinn. Thought at first it was the lamp where the fan dident spinn that was the problem. When I opened the lid I was a little surprised...Salty residue? no, burnt dust? no....It is the paint on the cooling fins that is peeling off. that lamp where the fan didn't turn, I got it working again, but see that the ball bearing or something has rusted. it may appear that the lamps do not tolerate moisture well, or that the heatsink/fan is undersized.
Red sea claim the coolingribs are aluminium, but am i double....
