LED circuit
W1900 Pro - XHP35
Offer current regulated MAX output with a single li-ion battery down to 3.0V (underload)
MAX output slowly reduces after 3.0V and operates until 2.65V (underload)
Built-in shut down voltage at 2.65V (underload) to prevent battery over-discharge (user may restart at lower levels)
Active thermal management feature (adjustment range 75%-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)
C3800 SC - Nichia 219C
Ultra low dropout voltage for longer current regulated runtime
Active thermal management feature5
Low internal resistance design offers up to 99% efficiency
High switching frequency (1MHz) controller for more compact circuitry design
Non-dimming constant current regulation for all output levels without flicking
Smart battery level report system
Energy saving feature5
Very low standby current (negligible)
Battery level report (discharging)
A blue LED indicator under the main switch reports the estimated battery remaining capacity
Flash once: lower than 20%
Flash 3 times: 20%-50%
Flash 3 times: 50%-80%
Flash 4 times: higher than 80%

Operations
Basic operations:
Turn on the light at MAX output by pressing the BLACK button switch. Turn on the light at LOWEST output by pressing the WHITE button switch
To turn off the light anytime, press and release the BLACK button switch.
Advanced:
For MAX output momentary on, press and hold the BLACK button switch for immediate output.
To switch between different brightness levels, press and release the WHITE button switch when the flashligh is on.
(For example: if you want to turn on the flashlight at the 3rd level, just press and release the white button switch three times from off.)
To enter hidden auxiliary levels, cycle through two set of regular output brightness level to enter
For instant MAX output - at any output level, press and hold the BLACK button switch. Release the button to return to previous level.
For instant Strobe output - at any output level (even) off), double press and hold the BLACK button switch. Release the button to return to previous level (or off).
Programmable startup level - Define the white button startup level by cycling to the desired output level and keep holding the white button for more than five seconds until the blue led indicator turns on.
Other features
LED direct soldering on copper for maximum heatsink ability
