The HEXBRIGHT FLEX is the last flashlight you will ever need to buy.
1. Quality and robustness of construction is best in class.
2. Every component is designed to be able to be replaced and/or upgraded.
3. Arduino allows you to customize it's functionality to whatever you need. Want a tactical 500 lumen blast? Need to be able to have 30 hours battery life at 50 lumens? How about a stobe that flashes morse code S.O.S? You can make it do all three or just one, or dozens of variations.
