I recently got two of these setups for my indoor garden:
I’ve been running one of them for approx. 3 weeks and the other one I plugged in last night. While doing some watering today I noticed the driver (Meanwell HLG-320H-48B) for the newly installed light was just warm, not hot like the other driver after it’s been running for an hour or more. When I realized the driver wasn’t producing nearly as much heat as it should I took a look at the panel and realized it’s only producing approx. half as much light as the other one.
I don’t even have the dimmers connected to either driver so both lights should be running at 100% by default but the newly installed one just seems to be running at half the power.
I have been trouble shooting for nearly 3 hours; trying different sockets, unplugging it for a while and waiting before plugging it back in, I also wired up the dimmer to the driver in question but it still just produced half the light while set at 100%. I also switched the wires to each of the drivers so they would run the opposite panels and I’m sure now it’s an issue with the driver in question because it will only produce half of the power regardless of what panel it’s wired to. The other driver has no problem running both panels at full blast, so I know the panels aren’t to blame.
Any advice, knowledge, or input that anyone can offer would be much appreciated. I imagine it’s extremely rare that a Meanwell driver would be faulty out of the box so perhaps there’s something I haven’t considered.
