Readings taken with an Apogee PAR meter, all pumps turned off in my tank. Tank had a water change yesterday. To keep the readings consistent I placed the meter's sensor in the tank and took a reading in High Efficiency mode on the Mitras then without moving the sensor changes the lights to High Output mode and took the reading. This was repeated at each level so the results are comparable with my situation.

Tank Specs; 140x75x55 deep (water level approx 57)

PAR readings in High Efficiency mode
240 (sandbed)
312
368
576 (water level)

PAR readings in High Output mode
340 (sandbed)
450
560
810 (water level)

Thanks for that info.

In my (uneducated) oppinion this gives a useable PAR spread of about 36"x30x 30" on high output, but please dont go by me see what you think yourself?

What settings are you using? Meaning how much "power" are you putting the lights thru?

happy to email it to whomever is interested, I am in the stage of ramping the lights up so the program isnt full brightness yet and will no doubt be modifed next week as im going to be measuring the light spectrum to fine tune the output a little

Please email it to me if possible. I can't wait to get my hands on Mitras. But I also don't want to burn my SPS.
