Led vs HPS growing

Hey so I have run a COB light setup for about two years and when the light was first built it was pulling 300 w

Today I tested it and it is drawing half that now.

Do drivers or Cobs draw less power as they age?

They shouldnt. Have you checked your meter? If its half power but light intensity isnt visibly affected then id say the meter might be wrong.

I found this : Sounds like these may be fading - they where China knock-offs

LEDs are long-life light sources which generally do not suddenly fail, but gradually lose their brightness and performance over time. In other words, LEDs fade and don’t actually blow.

That’s simply not true!

Makes absolutely no sense: yes leds lose output but would still draw the same watts at the wall. Id double check your meter and connections, especially if you have ground connected to the frame

It was the dimmer - I removed it and it puts out 302 watts

The dimmer was working between 23-300w for some time but now it is 23-150w
will pick up another as I like being able to dim them to slow down VEG at times.
Happened to my Northern Grow Lights (Robin's Old Company) Photon 180. But it would go up and down and flicker. Bypassed it and only have WFO now.

My lights have been running 3 yrs of 12/12, dimmers are the only things that have failed on my lights, so no dimmers anymore for me, give me full power.
