I am using an HLG 260W QB V2 rspec. I am growing in a closet and my house is a rental so I can’t make any modifications such as running ducts through the walls or ceiling. So far my light is only half way up and the room gets up to the upper 70’s even with the door open. My driver is very hot to the touch. As hot weather is approaching where I live I am planning ahead in case I have to remote mount my driver. Really the only option I have is to set the driver on the floor right outside the closet. I have seen heat sinks on Amazon and was thinking of setting one on the floor under the driver and another one on top of the driver. This would hopefully give the driver some breathing space instead of sitting on carpet.
I am also confused about the posts I have read that state it is necessary to ground the driver when remote mounting. The power cord for the driver is plugged into a 3 prong grounded outlet. That should be all that is needed for ground. Thanks.
