Light emergency! HLG Quantum Flickering

Hey everyone! I have HLG’s 260W XL QB V2 RSPEC LED Kit. I’m in the last week or so before harvest and it started flickering. I have emailed the company, but it is Sunday. All connections seem secure, and it still flickers when adjusted from lowest to highest setting.

Any ideas?

My guess would be bad connection or damaged wire rubbing on heatsink.


I think the same , double check all connections. Not just a tug but remove connector and make sure wire is touching and no insulation is hitting it(wire must be stripped far enough) as that may cause a flickering or weak connection.
