Frequently Asked Questions

The below FAQ covers a few of the questions we most often hear from our customers, if you have any questions we don't cover in this section feel free to shoot us an email at and we'll get back to you ASAP.

What is a Tactical Flashlight?

Our Tactical Flashlights are crafted from tough, durable, and lightweight aluminum; and are designed for professional use by law enforcement officers, military personnel, and security officers. Different from a run-of-the-mill torch, the ergonomics, user interface, and construction have all been designed around professional use in tactical situations. This includes powerful high modes to illuminate the operating environment and disrupt the vision of a potential attacker, tail switches for ease of use in high-stress situations and in conjunction with firearms, a strobe mode that can be used to disorient an assailant, and a robust metal casing that is both waterproof and shockproof.

How to select a flashlight?

When choosing the right flashlight, consider your needs first. If you're gearing up for outdoor adventures, tactical use, or just need a reliable light source around the house, the flashlight's features should match your purpose. Prioritize high brightness levels and a far-reaching beam for visibility in all conditions. Durability is key, so look for models made with tough materials like aircraft-grade aluminum. Opt for flashlights with extended battery life and compatibility with various battery types to ensure consistent performance. It's also essential to choose a model that's both water and impact-resistant. Remember, a lighter and more compact design makes for easier handling and portability. Features like multiple lighting modes, including strobe and SOS, can provide added functionality for emergencies.

How is my light powered?

Our lights are engineered for exceptional versatility and efficiency with many items featuring dual-fuel capability that allows them to operate with various battery types. This adaptability ensures you're never left in the dark, whether you're using readily available standard alkaline batteries or opting for the included rechargeable lithium batteries for their longevity and robust performance. This design ethos reflects our commitment to providing you with a dependable light source that adjusts to your needs without compromise.

How to maintain my light?

1)Wipe the flashlight off after use with a clean, dry cloth to remove any dirt or contaminants.
2)If the flashlight is contaminated with seawater or corrosive liquid, please wash it with clean water and blow it dry with a hair dryer.
3)To prevent battery drain and possible corrosion during long-term storage remove the battery and store in a cool, dry place.
4)Never use old and new batteries together, mix different brands of batteries, or mix Lithium and Alkaline batteries. Mixing of cells can result in dangerous battery leakage, damage, and sub-optimal device performance.
5)Do not put a working flashlight face down, this can burn the bulb or even start a fire.
6)If the tail cap sticks or doesn't rotate smoothly, apply a thin layer of silicone grease to the "O" ring.
7)Since lithium batteries self-discharge, it is recommended that they be recharged every 3 months even if you do not use your flashlight often.
