The Nitecore EF1 explosion-proof flashlight is designed for use by professionals in the hazardous environments associated with the petrochemical and pharmaceutical industries. The EF1 is classified as a Type II Non-mine explosion-proof electrical appliance as well as Class D explosion-suppressive flashlight. The handheld light can be used in hazardous areas (Zone 1, Zone 2, Type IIA, IIB, IIC, T1 – T5 levels as GB3836 rated). The EF1 can also provide illumination in locations such as factories, stations, stadia, railway tunnels and construction and smelting.
The EF1 measures 6 inches in length and weighs 8.82 ounces without the battery. The explosion-proof flashlight is built from an aircraft-grade aluminum alloy which features a 3mm body thickness. The flashlight also features a crenellated bezel, knurling for a firm grip and a HAIII military-grade hard anodized finish. The EF1 contains a Cree XM L2 U3 LED, a smooth aluminum reflector and an ultra-clear glass lens.
The EF1 explosion-proof flashlight can be powered by one rechargeable 18650 3.7V Li-ion battery, two CR123 3V Lithium batteries or two rechargeable RCR 123 3.7V Li-ion batteries. The flashlight produces a maximum output of 830 lumens, a beam throw of 270 meters and three light modes: High 830 Lumens 1Hr 45Min 18650 Battery – 1Hr 30Min CR123 Batteries; Mid 320 Lumens 3Hr 18650 Battery – 2Hr 45Min CR123 Batteries; Low 4 Lumens 150Hr 18650 Battery – 60Hr CR123 Batteries.
The Nitecore EF1 is operated by a sliding control switch located around the neck of the light. The switch provides access to the light’s various brightness levels. The switch can be moved to four numbered positions starting from 0 which is off through to 1 (Low), 2 (Medium) and 3 (High). The levels can be accessed in reverse order sliding the switch from 3 to 0. The explosion-proof flashlight features ATR (Advanced temperature regulation) technology which allows the EFI to adjust output performance according to its body temperature preventing damage from overheating. The EF1 flashlight pack includes a holster and lanyard.
