The flashlight features micro USB charging port, backlight LCD screen and is capable of delivering anywhere from 1lm to 1000lm of cool or neutral light using Cree XP-L HI. Package includes holster, charging cable, lanyard and spare orings. Registered shipping included as well in the price.
It’s easiest way to convert flashlight into micro USB rechargeable one. Internally it uses Panasonic NCR18650B 3400mAh cell and is longer like all protected cells at 70.7mm so be sure to check if it will fit.
Using BG points price can be lowered even more to:
This is exactly the same driver that powers Astrolux S1, Astrolux S41 and BLF A6 flashlights. It’s capable of delivering 6A of power (with quality high drain cell of course) and also features one AMC7135 for efficient low and moonlight modes. Sub lumen moonlight is possible with XP-L (3-4mA which would be about 0.2-0.4 lm). User selectable memory and two mode groups (3 and 7 modes accordingly), hidden blinkies include bike flasher and voltage indicator mode.
UI is very ergonomic - using short click you can go one mode upwards and using medium tap (0.5-1.5s - very intuitive once you try) you can change the mode backwards - no need to circle back whole mode bank.
This driver was conceived here at BLF, designed by Wight and the firmware was written by ToyKeeper. It’s open source and available here: ToyKeeper BLF A6 Firmware
This keyfob doesn’t need light exposition to glow at night - it uses gaseous tritium (isotope of hydrogen) in a process called radioluminescence and lasts ~25 years (due to radioactive decay of tritium it looses half intensity in about 12 years - it doesn’t stop emitting light abruptly like discharged flashlight - instead it gradually glows dimmer and dimmer).
Here’s article about how this works: wikipedia: Tritium illumination.
