FAQ's

How do I change the Batteries in the Gladius Flashlight?

This is an important issue and several customers have had difficulties here as they are used to installing batteries on conventional flashlights. Aligning the indexing pin on the tailcap/rotary dial is extremely important so as not to cause any damage to the Gladius or create any loss of function.

Please Review this document!

Remove the tailcap housing by rotating the metal sleeve by grasping the anti-roll flanges (not the rotary dial) counter-clockwise until the housing is released.

Install new, high-quality batteries, positive terminal first into the light. Night-Ops recommends Panasonic, Duracell or Night-Ops branded batteries. Carefully insert the housing into the body of the Gladius with light pressure and rotate it using the rotary knob until you feel it drop into its proper position. Then turn the entire sleeve by grasping the anti-roll flanges clockwise until tight. It is important that you ensure the tailcap housing is completely seated and tight so you do not experience intermittent loss of function.

Test the light to make sure everything is working properly.

DO NOT REMOVE the Bezel (unscrew the front end of the Flashlight)

This will void your warranty! The glass can be safely cleaned with a soft cloth and lightly wetted with mild window cleaner.

What type of batteries should I use?

Select and use batteries from a high quality manufacturer of 3-volt CR123A lithium batteries. Poorly manufactured batteries can cause catastrophic damage to the light.

Lithium batteries can explode or cause burns if disassembled, shorted, recharged or exposed to fire or high temperatures. Please handle with care. Do not mix new batteries with used or other types or mix batteries made by different manufacturers. Do not dispose of lithium batteries in the trash. If it is necessary to dispose of any batteries, do not do so by fire, mutilation or by disassembly, as this may cause toxic chemicals to be released.

The Gladius has not been specifically designed to accept rechargeable batteries, nor have we adequately tested rechargeable batteries in this light. If you put rechargeable batteries into the light that exceed it's maximum voltage load, you do so at your own risk. You will void your warrantee. You can quite possibly damage the circuit thereby rending the light inoperable.

Additionally, Pila brand rechargeable batteries installed in the Gladius will signal the power management circuit that the batteries are low in power. The Gladius will begin to emit a double flash in momentary and constant on Channels, which is the pre-programmed low battery power indication.

Will Night-Ops be offering its' own brand of Batteries?

How long will the batteries last, stored?

Batteries in the package can be stored 10 years and still retain 90% of their original energy. The batteries from a storage point of view should last 2 years once they are placed into the flashlight, the storage life will be reduced as the flashlight draws a nominal current.

How Strong in the Rear Tailcap Switch and Rotary Dial on the Gladius Flashlight?

It is durable and will withstand head high drops. It has excellent resistance to moisture, chemicals, solvents and fuels. Salt water will not be a problem. If your tailcap gets material inside of the tailcap, flush with water and/or compressed air. The tailcap is designed to be a dry design so do not interject heavier lubricants that will attract more material.

Why is there no knurling on the tailcap area?

We believe it is not the best design, as we want the thumb to freely slide along the body to facilitate smooth, fast channel switching.

Why did you choose and LED over and incandescent lamp?

LED’s are inherently shock-resistant and will last tens of thousands of hours as opposed to a high-output incandescent lamp. We have created a power\thermal management system that allows the Gladius Flashlight to go toe-to-toe and beyond that of many current incandescent flashlight offerings.

How long will the flashlight run on 1 set of batteries at full-power?

With a good set up batteries the Gladius Flashlight will run 90 minutes with no reduction in output.

How long will the flashlight run on its lowest setting?

Approximately 400 hours emitting .8 lumens of light.

What is the lumen rating of the Gladius Flashlight?

The Gladius Flashlight is estimated to be 80+ lumens in output. The Gladius is utilizing a Lumileds Luxeon III Star Power Light Source.

How are you going to rate your lights?

A lumen rating will be presented. It is a good starting point.
Current plans are to rate the light in terms of intensity at various distances and clearly define the beam pattern in terms of Hot Spot diameter and Corona diameter. Color temperature will also be stated.

How long does the LED on the Gladius Flashlight last?

This is defined in terms of lumen maintenance – The manufacture states that the LED will deliver on 70% lumen maintenance at 50,000 hours of operation based in independent test data. This projection is based on a constant current of 350 mA operation with junction temperature maintained at or below 90 degrees C.
