I've had Reef Optix III's on my display tank for ~6 years now. The only drawback I've found is that contrary to how they're advertised, they do rust over time. One of mine is worse than the other, but not to the point of needing to be replaced yet. I know they're touted as electrogalvenized, rustproof steel, but mine have rusted. They're 250 watt DEs on Ice Cap ballasts. Bought the package from Ocean Encounter if I recall.
