This UF602c is a very compact flashlight with simple to operate 2 mode (Low/High/off) reverse clicky tail cap button. This model is designed specifically for use with 3.7 volt rechargeable CR123 Lithium Ion batteries also know as LIR123 and 16340. This light has two light levels (low/high) and level memory utilizing the NJG-15 driver board with peak output draws .95A 

This batch of 602c lights require unprotected RCR123 batteries. There is some variation from batch to batch of the inner diameter battery tube. This batch has a 17mm inner diameter which is too small for most protected cells to fit.

This light uses a standard 17mm driver board and can be easily modified operating on different battery types or upgrade the emitter. Check our DIY category for optional driver boards and emitters.

Changing light levels: Modes are switched such as (Low -->  High --> REPEAT) by momentarily interrupting the power with in 2 seconds of powering on the light. Immediately after turning the light on, tap the power switch to quickly interrupt the power, this will signal the driver board to change output modes. Modes are remembered if the power is left off for more than two seconds. If the light has been on for more than two seconds, modes can be changed by either turning off the light first or by double tapping the power switch.
