It seems like I got one of the “new” TSL-2000 lights. It has 2 drivers, but also a 3rd box with dimmer knob and dimmer on/off switch, plus the power switch for the light itself. I understand how to use the dimmer, I think. But what I don’t understand is what the adjustment screws are for under the white plugs on top of both drivers. I can’t find anything online related to it, just a bunch of stuff about the older lights with the dimmer adjustment being on top of the drivers, under a white “plug”, and it looks totally different than mine does. I’ve tried to attach a pic of what I’m confused about. Hopefully it attached and someone here can explain what this is and what I should do with it. Thanks in advance. Sorry for the horribly worded post. Not really sure how to even ask the question as I’m unfamiliar with QBs and Mars Hydro.
