Forest Tiger SLH-H541-T6 Cree XM-L T6 900lm 5-Mode White Light Flashlight - Black (1 x 26650)

Pros: the larger 26650 battery give a lot more run time than the 18650 models and the lower internal resistance handles the current better with less waste as heat. Speaking of heat, the added mass of the larger size keeps it cool even after long sessions on hi. (hard to tell from a photo but it is roughly double the mass of the average 18650) Everything you need is in a well made heavy card stock box with a magnetic flap on the top.

Cons: The threading on the case for the end cap is very poorly done, so poorly that as it arrived it is almost impossible to screw in on snugly (all 3 in my order were like this. The problem is the threads were formed with dull equipment in thin aluminum with too much force. To fix the issue I inserted a tight fitting wooden dowel in the opening and carefully pried in a circle to expand the threads out. While this did fix the issue the material back there is delicate and it may not last.

Other: For the price it's a great match set after it's fixed.
