This powerful and long-running rechargeable lamp is an advanced dual LED work light, engineered to help you get the most critical jobs done right, almost anywhere.
The Knucklehead’s powerful magnet, integrated stowable hook, and stable base give you more options for placement. The super-strong 135 lb. pull rare-earth magnet is protected by a durable nickel plated steel housing and removable rubber boot.
You can stand it up, stick it on steel, hang it from nearly anything, or just hold it—then use the innovative 360° articulating head to aim the optimized beam precisely on the area that needs it.
Dual C4 LED technology casts a broad, bright, working light.
Streamlight engineers took their most advanced C4 LED Technology and cast it in a very different
light. The Knucklehead harnesses the bright white light of two powerful, virtually unbreakable C4 LEDs in a unique hybrid optical system designed to evenly illuminate a wide area, while literally highlighting a specific zone for focused work in the beam’s smoothly optimized center.
The shock-proof LEDs are thoroughly protected against moisture, dust, and impact behind an unbreakable polycarbonate lens with a silicone anti-scratch coating and O-ring sealed in a rubber-armored heavy duty bezel.
Advanced digital power regulation for steady output, longer runtime, and maximum efficiency.
Streamlight’s microprocessor technology regulates power to deliver virtually full light output for more than 90% of the ANSI specified runtime.
On High setting—an exceptional 200 lumens—the rechargeable Knucklehead Ni-Cad battery pack provides up to 3.5 hours of continuous runtime before power starts to fall off. At the Low setting it provides a very functional 63 lumens—more than enough light for less-critical operations—for up to 16 hours.
Or you can provide a soft flood of light for survival situations or general navigation for as much as 20 DAYS of continuous operation. And like the proven Survivor, on which it is based, the Knucklehead’s dual power system lets you quickly replace a depleted Ni-Cad pack with 4 AA alkaline batteries. Runtime should never be a problem.
Stick it to steel
or any flat ferrous metal surface with its super-strong magnet.
Hang it up
with its convenient retractable hook.
Aim it with ease!
Choose a Knucklehead light with a battery/charger package from among a variety of options to fit your application.
360° degree rotation and 210° of vertical articulation makes it very easy to aim.
The Knucklehead LED fits all existing Survivor charger bases. You can order it with just the AA battery adaptor, and use any batteries or charger you have now, and upgrade your lighting “arsenal” at minimal cost.
Or you can choose from a range of Streamlight charger options for AC and or DC operation. One-hour fast chargers with full charge indicators are available for AC or DC power sources. The universal Steady Charger, which requires up to 10 hours for a complete charge, can be used with 120V AC or 12V DC depending on the charge cord chosen. Optional 5-unit Bank Chargers are also available for AC or DC operation.
