Another variant of the FW3A is here - the FW4A! Like the name suggests this FW4A has 4 x XP-L HI emitters instead of just 3, which results in a brighter output
The FW4A is a compact yet powerful quad LED EDC flashlight. With the only 92.6mm in length, it delivers a max 3600 lumens amazing output by a single 18650 battery (minimum need 10A, see recommended batteries below). The smooth bottom electronic metal switch controls various functions including smooth ramping, stepped mode setting, strobe etc.
Do not remove battery via tailcap for the FW series, always remove from the head side

User Interfaces And Features
By default the FW4A is set to use Smooth Ramping for mode changing
Direct access to turbo mode shortcut.
A more conventional Stepped Ramping UI is available if you prefer discrete modes level. (Number of steps is configurable)
Momentary mode useful for signaling purposes or rapidly/briefly lighting up targets. To exit this mode, physically disconnect power
Muggle mode uses reduced output and features
Electronic lockout for safety and low momentary.
