        Safety Instructions

        Safety Instructions

        The safety instructions have been classified according to the seriousness of the risk for each of our flashlight products, as follows:

        DANGER: “Danger” indicates the existence of a hazard that could result in death or catastrophic bodily injury, if the safety instruction is not observed.
        WARNING: “Warning” indicates the existence of a hazard that could result in serious bodily injury, if the safety instruction is not observed.
        CAUTION: “Caution” indicates the existence of a hazard that could result in minor bodily injury or property damage, if the safety instruction is not observed.
        NOTICE: “Notice” contains general information that relates to the safe operation of the flashlight, and it’s battery and charging equipment. 



        • To avoid risk of damage to eyesight, never look directly into the beam when the light is on, nor shine it directly into another person’s eyes.

        • Any battery may rupture or explode if put in a fire or otherwise exposed to excessive heat. To avoid risk of injury, DO NOT expose batteries to fire or excessive heat.

        • Never short-circuit a battery pack by bringing the terminals in contact with a metal object. Explosion, burns, other bodily injury or fire could result.

        • Never try to disassemble or repair the flashlight or charging accessories. Electric shock or fire may result. 

        • Never alter the plug on your charging accessories. If the plug will not fit into the available outlet, have a proper outlet installed by a qualified electrician. Trying to plug into an improper outlet can result in electric shock or fire.


        • Any battery may leak harmful chemicals which may damage skin, clothing, or the inside of the flashlight. To avoid risk of injury, do not let any material leaked from a battery come in contact with eyes or skin.

        • Never heat and never attempt to disassemble the battery pack, as that could cause leakage of caustic electrolyte. In the event of skin contact, wash the affected area immediately and obtain prompt medical attention.

        • Never allow liquids to spill on the Direct Plug-in Charger and DO NOT charge outdoors, as the unit is not waterproof. Exposure to rain or other liquid could result in fire or electric shock.


        • Never store or transport flammable liquids, gases or explosive materials in the same compartment as the flashlight or its accessories, as possible sparking in the equipment could ignite a fire or explosion.

        • Always secure the flashlight in its storage case. Never place the flashlight on the passenger seat or anyplace else in the car where it can become a projectile during a collision or sudden stop.

        • Never expose the terminals of the Lithium-Ion Battery to any metal object. When transporting a Lithium-Ion Battery outside the flashlight, wrap it or place it in a plastic bag, or put insulating tape over the terminals.

        • DO NOT charge or operate the flashlight near flammable materials.

        • DO NOT charge battery in gas-tight enclosures as hydrogen gas is emitted under certain conditions and can explode if concentrated and confined.

        • DO NOT operate flashlight with the lens off and the LED on and exposed. Personal injury or damage to heat sensitive materials may result (e.g. plastics, rubber, cloth fabrics, etc.)


        To reduce the risk of harm to your flashlight and others:

        • NEVER allow children to play with, or operate the LED flashlight!

        • Locate power cord away from foot traffic, heavy objects and other causes of abrasion or stress, as it presents a fire and/or electric shock hazard.

        • Never pull on the power cord when unplugging the Direct Plug-in Charger. Grasp the Direct Plug-in Charger(D) main unit and pull to avoid damage.

        • Between uses, disconnect Direct Plug-in Charger(D) from power source.

        • DO NOT use non-rechargeable batteries in your rechargeable flashlight.

        • For prolonged storage, remove battery and store apart from flashlight.
