I just got a CoralVue 14k 150w metal halide bulb from Ebay. I put it in and it's waaaay dimmer than the previous 6,500k bulb. It's so dim that the corals almost look shaded. When I stare into it (dumb, I know), I can look at it for a while without being blinded, much more so than the previous 6,500k.
I doubt its ability to grow my seagrass and corals.
Is this natural for 14k bulbs, or should I return it?
