Looking for a 50-60mm heatsink "sleeve" for a 25mm module.

Aluminum, so not too heavy. Finned or not finned.

Gutted this old Ryobi flashlight and a dead battery pack.

Looked at building into it a 7.4v LiPo battery pack, but going to go cheap at first and try a 6AA holder with NiMH cells (8.4v charged to 7.2v discharged).

The weight at the bottom makes it sit nicely and the head pivots great.

Nice complement for this 7W 445nm module!

That said, it pulls down 1A at 7v, so the NiMH AA cells may not do well long term, but it will be an OK start. I have tons of AA NiMH cells and chargers.
