This is the Convoy S2+ flashlight with the updated v2 Convoy driver.
This driver has two variants. One is similar to the old kBiscotti driver in that it can be configured to your needs, but it also has thermal regulation and no visible PWM.
The second option is a non-configurable 4 mode driver with mode memory. The modes for this driver are as follows:
0.1%-3%-30%-100% max current output is 6000mA
The brightness of both drivers is approximately 1800 lumens at 100%.
The light has a copper DTP board, anodized tail threads, a smooth reflector, and an AR coated glass lens. It takes an 18650 battery.
