I recently watched a video on vivid aquariums website about par ratings and in the video the guy was measuring par under water in various depths and areas of the tank and his measurements ranged from 200par to 370par. Reason I'm asking this is because I'm looking at getting a led fixture and want to make sure I get a good one. I'm looking at a few on eBay. A 120w and a 165w. No there not taotronics or some of the other fancy ones but it's what I can afford. The 165w says it has a par rating of 28 and the other just says output optimized for par. So I'm a little confused. Can anyone help explain.
