SureFire Fury IntelliBeam FURY-IB-DF – 1,500 Lumen Auto-Adjusting Dual Fuel LED Flashlight
The SureFire Fury IntelliBeam FURY-IB-DF is a pocket searchlight with a brain. It takes the 1,500-lumen capability of the Fury DFT and adds SureFire's proprietary IntelliBeam circuitry, which reads the environment and adjusts output anywhere between 15 and 1,500 lumens — faster than your eye adapts, and without you touching a thing. Walk from a dark alley into a lit stairwell and the light simply follows you.
When you want the decision back, a double click of the tailcap overrides the automatic mode and locks the SureFire Fury IntelliBeam FURY-IB-DF to high output only. Its smooth parabolic reflector throws a hybrid beam — a bright, far-reaching center with generous spill so you keep your situational awareness. Dual Fuel means it runs on the included SF18650 rechargeable lithium-ion cell or on two 123A lithium primaries, which is the difference between a light you charge and a light you can always feed.
Shoppers cross-shopping a tactical flashlight, a rechargeable EDC flashlight, or a USB rechargeable 18650 flashlight generally land here for the same reason: Mil-Spec hard-anodized aluminum, an IPX7 rating, and SureFire's USA build.

Frequently Asked Questions
What is IntelliBeam on the SureFire Fury IntelliBeam FURY-IB-DF?
IntelliBeam is SureFire's proprietary circuitry that samples the ambient light in front of the light and sets output automatically. On the SureFire Fury IntelliBeam FURY-IB-DF it moves anywhere between 15 and 1,500 lumens, adjusting faster than the human eye adapts, so you never blind yourself on a close-up task or run out of reach at distance.
What battery does the SureFire Fury IntelliBeam FURY-IB-DF use?
The SureFire Fury IntelliBeam FURY-IB-DF is a Dual Fuel light. It ships with one SF18650 rechargeable lithium-ion battery that charges through its own built-in USB port, and it will also run on two 123A lithium primary batteries. The SF18650 is required for the full 1,500-lumen output; on 123A primaries the SureFire Fury IntelliBeam FURY-IB-DF peaks at 1,100 lumens.
How bright is the SureFire Fury IntelliBeam FURY-IB-DF and how far does it throw?
Maximum output on the SureFire Fury IntelliBeam FURY-IB-DF is 1,500 lumens with the SF18650 cell, with a rated beam distance of 369 meters. Running two 123A primaries gives 1,100 lumens and 316 meters. High runtime is 2.25 hours on the SF18650 and 1.75 hours on 123A cells, with total runtime of up to 40 hours at the lowest automatic settings.
Can you override the automatic mode on the SureFire Fury IntelliBeam FURY-IB-DF?
Yes. Press or click the tailcap of the SureFire Fury IntelliBeam FURY-IB-DF to select IntelliBeam mode; return to off and press or click again within two seconds to lock it to high output only. That gives you a conventional tactical light whenever the automatic behaviour is not what you want.
Is the SureFire Fury IntelliBeam FURY-IB-DF waterproof?
The SureFire Fury IntelliBeam FURY-IB-DF carries an IPX7 liquid ingress rating, which covers temporary immersion. Its Mil-Spec hard-anodized aluminum body, tempered window, and o-ring seals are built to resist corrosion and moisture in normal duty and outdoor use.
Is the SureFire Fury IntelliBeam FURY-IB-DF good for tactical and EDC use?
It is one of the more capable pocket searchlights available. At 5.6" long and 6.5 oz with batteries, the SureFire Fury IntelliBeam FURY-IB-DF is still pocketable, and the automatic output plus hybrid beam suits duty, patrol, search, and outdoor use where lighting conditions change constantly. SureFire builds it in the USA.
