Red Sea LED 90 PAR loss?

[MarcosDelgado0]

This might be a dumb question but can LEDs lose PAR over time? I was tested the lighting on the new frag tank and checked out the Max E 170 while I had the PAR meter and it’s showing crazy low? Literally at the surface centered, I’m only reading ~120 PAR. At the peak of my rock work which is about 3-4” below the center of the tank, I’m only getting ~60 PAR. Frag racks where my torches sit are showing 20-30 PAR. Could this be accurate? On the frag tank with the Nicrew 150s the numbers are what I expected because I matched the lighting height of someone on YouTube with the same frag tank and lights but the Red Sea LED 90s seem way off. I found a chart with PAR measurements for the Red Sea LED 90 and at center surface where I should be getting at least 500 PAR, I only get 120.

Possibly dead LED channels. You can test this by turning on each color channel independently and seeing if there's light. Also can test by measuring the wattage used at full power and all color channel on; should be 90 watts.

Good idea, thanks. I’ll try that

How long have the lights been operating ? As in, how long have you had them?

March 2023 is when they first were setup

Led definitely can lose par , but usually will take a long time .

Usually def not in first year like that for sure.
Corals doing ok?

Corals are all opening up and doing ok. Growing even. I wouldn’t have thought there was an issue. I emailed Red Sea and they are sending me a replacement power supply to trouble shoot. I don’t think that is the issue but I think they want to try that before sending me a replacement light to switch out

At least they are on it. Hope it resolves soon.
