The Twin-Task 3C UV flashlight features three lighting modes and the latest in LED technology. The six 390 nanometer (nm) UV LEDs provide ultraviolet light for detection of fraudulent documents, forensic investigations, or detecting engine and HVAC leaks. The white C4 power LED with its textured reflector provides an even beam, along with piercing hotspot for distance. The push button head switch sequences through three 390 nm LEDs, six 390 nm LEDs, C4 power LED, and Off. Market applications include, but are not limited to, industrial, law enforcement, security, and automotive use.

LEDs don't require periodic bulb replacement like incandescents and are virtually indestructible. Streamlight's revolutionary C4 technology combined with an innovative Streamlight-engineered reflector provides sharp, focused light that rivals incandescent intensity without giving up the durability and longevity of an LED. Since LEDs have a long life and won't burn out or won't break, they never need to be replaced. More powerful and more economical, Streamlight LED lighting tools pack a lot more power with ultra-bright white beams and long illumination times. They are extremely dependable and cost-efficient.

The Twin-Task 3C UV flashlight features C4 LED technology for extreme brightness, impervious to shock with a 50,000-hour lifetime. Its six 390 nanometer UV LEDs have a 100,000 hour lifetime. The Twin-Task features three light modes: white C4 LED with 3739 candela peak beam intensity, 185 lumens and a beam distance of 116-meters; six UV LED with 44mW measured system output; and three UV LED with 30mW measured system output.

Powered by three C size alkaline batteries (sold separately), the Twin-Task 3C UV flashlight's C4 LED has a run time of 27 hours, the six UV LED has a run time of 63 hours, and the three UV LED has a run time of 81 hours.

Designed for durability, the Twin-Task 3C UV flashlight features a machined aluminum case with a non-slip knurled grip, a matte black anodized finish and an unbreakable polycarbonate lens. It is IPX4 rated for water-resistant operation and 1-meter impact resistance tested. All openings are O-ring sealed.

Weighing 16 ounces with batteries, the Twin-Task 3C UV flashlight has a length of 9.02 inches, a major diameter of 1.68 inches, and a body diameter of 1.26 inches.
