ReefBreeders Pico LED V2 Stopped working

[kdsands88]

I bought a ReefBreeders Pico LED V2 Refugium from Detroit Reef Club on November 18, 2025. As of today February 21, 2026 the light will not come on.

There is no manual to understand the colors (Blue, Green and Red) from the inline controller. The controller is currently Green, but the light will not turn on. I am not sure if it is a timer issue and how to reset the timer.

What should I do?

Well it " looks" like you can take the timer out of the circuit
Then it should light to 100%
unless the power supply is shot (likely reason for your problem)

Any 12v DC switching power supply rated 1000mA or more should do.
Looks like center is positive.
Specifications are on the wall wart.

As you can see from the above picture the ReefBreeders Pico LED V2 Refugium does not have a controller than can be replaced. It is part of the light.

Oops, looks like that was for ver1 not 2.

Thank you Logan from ReefBreeder for replacing my light under warranty. Yes it was the light, not the transformer.

Also, Thank you Zach from Detroit Reef Club to allow me to pick up the light in Detroit. This saved time and money to get a replacement sent to Canada.
