Hi all I have a small room 8x8 with a 4x4 tent and the driver was at 104f. I got another hlg 260 xl and was worried about the heat generated so I got a heat sink and put them outside the room very happy and cooled down the drivers.
Makes sense. Did you tap the screws into the sink or through bolt?
@beardless I taped them 8-32 x 1/2 worked great
