LED circuit
W2200 SC - XHP50.2 LED
W1900 SC - XHP35 LED
Current regulated output for all brightness levels
Low voltage warning at 2.8V (lowers output to the lowest level to extend remaining runtime)
Built-in shut down voltage at 2.8V (if voltage reaches 2.8V at the lowest level, the flashlight will turn off)
Active thermal management feature (adjustment range 70%-100%)5
Synchronous boost controller with ultra low resistance mosfet which offers up to 95% efficiency
High switching frequency convertor for more compact circuitry design
Non-dimming constant current regulation for all output levels without flicking
Very low standby current (negligible)
Charging circuit
L1000 Micro
5V USB input (requires 1A or higher)
Dual mosfet design for maximum efficiency
1A MAX charging current
Uses standard micro-usb charging plug, supports bi-direction insert
Constant current / Constant voltage charging logarithm
Small current charging for low voltage battery (less than 2.9V)
Extends battery cycle life by charging battery that reads 4.1V or lower
Precise voltage detection design +/- 1%
No trickle charge
Smart charging level report system
Battery level report
A blue LED indicator under the main switch reports the estimated battery remaining capacity
Flash once: lower than 10%
Flash twice: 30%-50%
Flash 3x times: 50%-70%
Flash 4x times: higher than 70%
Charging level report (charging)
A blue LED indicator under the main switch reports current charging level
Flash once: lower than 50%
Flash twice: 50%-75%
Flash 3 times: >75%
Constant on: 100% (done)

Operations
Turn on the light at MAX output by pressing and holding the on/off switch button
Turn on the light at LOWEST (programmable) output by pressing and release the switch button quickly (within 0.5 second)
(UPDATED) To program the LOWEST startup output, switch to the desired output level and WITHIN ONE SECOND switch off and on the flashlight for three times. In rare occasion user may experience the absence of lowest output level from a brand new purchase. If this is case, set the programmable startup level once will initialize the memory setting and will take care of this issue once and for all.
To turn off the light anytime, press and release the on/off button switch while it is on.
To switch between output levels, with the light turned on, press and hold the on/off switch for longer than 0.5 second to switch to next output. Press and hold the switch will cycle between all levels.
To access AUX blinking mode, with the light turned on, cycle through at least two sets of regular brightness level to enter
Charging:8
Remove the waterproof silicon cap and insert the charging power plug to charge.
Blue side LED indicates the battery is being charged. It reports charging percentage by blinking.
Controls
LED direct soldering on copper for maximum heatsink ability
