I've been looking for a right angle flashlight, preferably powered by an 18650 cell, with a brightness dial to adjust it from minimum brightness up to full power. Does such a thing exist?
Take a look at First Light USA's Tomahawk, T-Max, and Troq. Each offers multiple levels of output, and most have various colors of secondary LEDs. The UI is different than most lights, but it is easily learned.
………..I can recommend the Fenix MC11. Right-angle head with adjustable angles. 1AA. Three brightness levels: 3, 50, 105 lumens. Burst 155 lumens.
I liked the review of the Spark SG6 here,…………………….
The MC11 needs a 18650, IMO. If it was capable of using a 18650, and had a high output of 500-600 lumens, I would buy it in a heartbeat.
