Details:
  • Perfect for Cree XM-L series LEDs -- especially with T6 and U2
  • Dual PCB layout, 10mm total height
  • Designed for Cree XM-L LED emitters
  • Also works with four MC-E's and four SST-P7's connected in parallel
  • 2800mA maximum current output
  • Low voltage warning battery protection mode triggered when voltage drops below 3V (in 1-lithium configuration) or 5.8V (in 2-lithium configuration): automatically switches to the lowest output setting, and blinks periodically
  • Modes:
    • Group 1: Lo (5%) > Mid (50%) > Hi (100%)
    • Group 2: Lo (5%) > Mid (50%) > Hi (100%) > Strobe > SOS
To toggle mode group: 
  • Switch to Lo (5%) mode and count exactly 5 seconds. As soon as the flashlight blinks, half press (or quickly toggle power) to go into the other mode group.

Starting 06/20/2014, we are shipping the updated version.

Cheap, good, small, easy to use. Mode memory works great for me, and i also like the SOS mode is hidden in double-OFF-ON-OFF-ON click. Easy to solder to bottom plate
CONS
Low battery warning is stupid, looks stupid and kills the battery. High mode stabilization stops @~3.8V, so all battery terminals and wires have to be very good quality not to loose extra power.
Mine came with blue PCB, and i was never able to switch between the groups, i just have Low-med-high with 1 click and SOS strobe with double-click I use it in 1S DIY project, it is not just a flashli... (read full review)

Driver is good, just the manufacturer changed the firmware. In Gate you can go if you quickly go from min to max mode. Transition as early in the group where 5 modes min-medium-max-STROBE-SOS anymore.... (read full review)
