This configured SureFire M600DF combines high-output illumination with a versatile mounting and control system tailored for modern weapon setups. At the core is the KE2-DF head, delivering up to 1,200 lumens of focused white light using the included CR123A lithium batteries. The light supports SureFire’s dual-fuel capability, allowing use of an optional SF18650B rechargeable battery (not included) to achieve up to 1,500 lumens.

Mounted via the Haley Strategic Thorntail X 1913 Offset Light Mount, the M600DF is positioned closer to the handguard for improved ergonomics and a lower profile. The offset design allows for seven mounting positions around the rail, enabling optimal light placement for thumb-over-bore grip techniques.

Activation is managed through the UE tailcap and SureFire SR07 remote pressure switch, offering both momentary and constant-on function via a 7-inch cable with integrated MIL-STD-1913 rail clamp. Original box not included.
