I recently rented a PAR meter from my local fish store and spent a day measuring and gathering PAR readings from around my mixed reef tank. I wanted to get a complete picture of how the two 160w Maxspect Razors (R420r) LED lights hanging over my tank interacted with the rock work so that I could make the best choices possible when placing corals. I took a lot of measurements. I tried to get a reading for just about every nook and cranny I could fit the PAR meter’s sensor into - more than 40 positions. I also took measurements for each position at each of the settings at each of the 6 time points in my program. Like I said - a lot of measurements ;D I thought I might share it, just in case it comes in handy to anyone else. particularly to Maxspect razor owners, since those are the type of lights I'm running over this tank. Below is a JPG and a high-res PDF of the PAR map I came up with what do you think?
