Excellent Capacity: The i3T 2 comes with an included AAA battery, but you can also use a 10440 Li-ion battery with PCB protection (max length 44 mm), which can boost the maximum output up to 300 lumens.
Brand New Clip: The clip on the i3T 2 is now stuck between the battery cover and the body -- never worry about falling off and it allows for deeper pocket carry.
Start At Your Preferred Mode: Both soft and heavy activation can be set default mode by simple operation, making it more obey to your will.
More Backup With Lower Temp: Compared with the i3T, this 2nd generation gets 31% more battery life, and 71% more runtime in High mode. We optimized the circuit to ensure its surface temperature less than 113*F even during long-time work.
