I ordered my replacement 96w PC bulb from Ocean Aquatics (Panasonic brand square pin config). Extremely happy with the light output from a full 10000k bulb. Much better, more useful lighting than the 50/50 bulbs & much brighter than Corallife. Gonna switch over to these Panasonics on my other units too. Same reaction from my friends who see a noticeable diff. between my previous bulb & the new Panasonics.
These comments would be the same even if I didn't work P/T at OA
