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.
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.
