NICE!! I also run a 650r in a 4x4. I love it but upgrading to a 8” fan soon. When the tent is closed it gets to 79-80, I try to keep the tent at 75. You are supposed to keep the light 30” away. I have been as close as 18”, but not close to full power. I also raised the light so it’s only 10-15” from the top of the tent. This has been fine but I added 2 fans pointed on the heat sink, and seems great for the last 8 months or so.
