SureFire KE2-DF — High-Output Dual Fuel Scout Head
The KE2-DF is the standard bezel of SureFire’s M640DF Scout Light Pro, available as a standalone head. Its proprietary TIR lens creates a hybrid beam: enough throw for tactical distances, wrapped in generous surround light that preserves situational awareness at close quarters. On a rechargeable 18650 it produces a full 1,500 lumens; on two 123A primaries it still delivers 1,200 lumens.
Dual Fuel Advantage
Rechargeable 18650 power keeps running costs near zero during high-volume training; 123A lithium primaries with their ten-year shelf life guarantee the light fires when it matters. The head swaps between them with no adjustment — just screw it onto any Dual Fuel Scout body.
Key Features
