1,500 Lumens

The M600DF Ultra Scout Light is a lightweight, compact WeaponLight featuring an ultra-high-output LED that delivers 1,200 lumens of blinding white light with 123A batteries and 1,500 lumens of light with the SF18650B MICRO-USB rechargeable lithium-ion battery. A proprietary Total Internal Reflection (TIR) lens shapes the recoil-proof LED’s light into a beam with plenty of reach but enough surround light to accommodate peripheral vision, making the M600DF ideal for medium to longer-range applications. The rugged M600DF attaches quickly and securely to any MIL-STD-1913 rail via its integral thumbscrew clamp. A slight press of the Z68 tailcap switch will activate the momentary-on, while fully depressing the tailcap until it clicks will activate constant-on. Constructed of lightweight aerospace aluminum, with a Mil-Spec Hard Anodized finish, and O-ring sealed to keep out the elements, the tough M600DF will endure combat-like conditions without any sacrifice in weapon maneuverability.

Scout comparison

I have 3 Surefire Scout Weapon lights. #1 is about a decade old that started out at about 60 lumen, was upgraded twice and now has a 200 lumen KX2C head. #2 is a few year old Scout Fury with a 500 lumen KE2-A head. #3 is the just released 1,500 lumen KE2-DF Duel Fuel. I do nuisance wildlife management and the 200 lumen is fine for crossbow or subsonic .22lr use at close range. The 500 lumen is good for medium range slug gun use or centerfire rifle, but just doesn’t have enough juice to reach out far enough with rifle use. I have to go to an Olight M3X 1,200 lumen for long range rifle use. When the 1,500 lumen Scout was announced I jumped on it expecting to ditch the large Olight and have a small, bulletproof Surefire. Unfortunately, the Duel Fuel has a lot of “spill” or flood light but reaches out no father than my existing 500 lumen Scout. It lights up a somewhat bigger area if that’s what you need, but don’t expect it to give you much longer range than your 500/600 lumen Scout does. Lights up a bigger area, and uses the 18650 battery are the advantages I've seen.
