Gladius Flashlight Q&A
How do I change the Batteries on the 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.
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.
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.
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.
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 mode switching.
Why did you choose and LED over and incandescent lamp?
LED’s are inherent shock-resistant and have 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 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 has not yet been tested in an integrating sphere to determine this. When this data is obtained it will be post. We are estimating 80+ lumens.
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.
Are you going to come up with other variants of the Gladius Flashlight?
Yes. We are going to do some body changes as well as material changes.
Is the Gladius Flashlight weapons mountable?
Yes. It is more than rugged enough to be mounted on all standard small arms. The Gladius flashlight body is 1” is diameter is so a plethora of current mounting solutions in available to the user.
What pouch do you recommend to carry the Gladius Flashlight for Duty Use?
The best option from BlackHawk Products Group is this pouch.
Blade-Tech offers an excellent duty holder for the Gladius - Select Night-Ops Gladius.
Is there a remote switch available right now?
Unfortunately not, we are currently developing a remote switch capability for the Gladius.
Is Night-Ops going to develop its own mounts?
Yes they are in process.
What type of finish is on the Gladius Flashlight?
It is a ceramic based coating. It maintains excellent bond strength even after exposure to extreme high temperatures. Other performance properties include high chemical and corrosion resistance, unmatched hardness, and outstanding UV resistance. Uses include clear protection, performance motor sports, industrial coating applications, firearms coatings, gas turbine engine coatings, and decorative performance coatings. Additionally we can color match exactly as well as maintain excellent part to part color uniformity not possible with Hard Anodization found on many current flashlights.
How hard is it to change Modes on Gladius Flashlight? (Momentary, Strobe, Constant ON and Adjustable)
Exceptionally easy and intuitive.
How about changing Modes under duress?
The professional challenge for us in developing this tool was packing the most USEFUL power/options into an interface and that one under duress could reasonable expect to operate given a moderate amount of familiarity with the new tool; say one set of batteries worth of personal training.
With the additional options, we highly recommend that you become familiar with the flashlight by using in conjunction with other tools and tactics prior to deploying it operationally. Manipulating the flashlight rotary dial when doing other mundane tasks will also help in becoming familiar with the fast action and Mode locations of the dial. Learn to use just your thumb for all mode switching. It will become second nature relatively fast.
Will the Gladius Flashlight slip in my hand if it becomes wet?
The light has excellent retention when it becomes wet. The body of the light was specifically designed to have an excellent balance and feel. Particular attention was paid to the retention issues as well as creating a design that would have maximum flexibility in terms of flashlight\handgun techniques.
Using the light for administrative, navigational, or stealth purposes is generally a more time forgiving situation. Remember, the light can virtually instantaneously be brought from the lowest level to its highest level using a couple different methodologies.
Why doesn't the Gladius Flashlight start off in the lowest level of light when placed in Channel 3 (Constant On/Adjustable) - Mode 1?
The light is primarily designed to be used in confrontational situations. As these situations can unfold extremely quickly, the designers of this light ensured no matter what Channel you select, the user will always have enough light at the onset to correctly identify and potentially engage hostile threats with a sufficient level of light in a close-quarters situation.
Although this is the factory default setting can I change it?
Yes. Through a series of relatively easy to remember, yet almost impossible to duplicate by accident, the operator can change this channel so that the light starts off at the lowest level and works it’s way up. This is referred to as Mode II.
Additionally the operator can set Channel 3 up to “remember” the last level of light and return to that level upon tailcap switch activation. This is referred to as Mode III.
All Modes can be interchanged, but only one Mode can be selected at a time.
What is the procedure to change Modes when the Rotary Dial is on Channel 3?
Instructions for User Initiated Channel 3 Mode Changes:
Note the Mode changes are cycled in a set sequence:
1-2-3-1 and so on.
To change from Mode I (factory default) to Mode II, press and HOLD the tailcap button when the rotary dial is set for CONSTANT ON-OFF operation until the light blinks twice (approx. 10 seconds). Repeat the process. The next time you activate the tailcap, the light will start off in Mode II
To change to the next Mode, Mode III, initiate the same sequence.
To change from Mode III back to Mode I (factory default), initiate the sequence again.
Note: If you are a member of a team that carries the Gladius, having several different configurations of lights (different Channel 3 programming) within that team could lead to confusion. Please consider this when changing the factory default settings for this channel.
What carrying methods are available for the Gladius Flashlight?
Right now BlackHawk has several Nylon Pouches that are designed for the Gladius Flashlight. The bezel diameter is such that if you own a SureFire V70 duty flashlight holder, the Gladius Flashlight will snap right in bezel down. Night-Ops is developing its own proprietary holder.
Can you use a Lanyard with the Gladius?
Yes. There is one provided with the flashlight and there are small holes drilled in the anti-roll flanges to accept the lanyard.
Why strobe the light mode?
Strobing light is particularly difficult to look at and orient to. It will ultimately lead to lower levels of force and better officer safety in many hostile encounters. The strobe function on this light is not a toy and it should not be used as such.
Is this light going to put people into a seizure when I use it to deal with a threat?
This is an important question and the phenomenon is known as photosensitive epilepsy.
If the subject is being hostile, then any number of less lethal alternatives can be selected to handle them. All have downstream consequences if deployed at the inappropriate time or manner. The use of light is clearly at low end of any disruption protocol.
A certain percentage of the population can experience extreme reactions to strobing light; be prepared for severe disorientation and even seizures in some individuals.
Contrary to popular belief, only a small percentage of people with epilepsy are especially sensitive to flickering light patterns, such as sunlight, strobe lights or computer screen flicker. This condition is known as photosensitive epilepsy. A flickering fluorescent light, the flicker of sunlight while driving past standing trees or on water and other reflective surfaces, certain video games, or flashing strobe lights can trigger seizures in photosensitive people.

Given 2.5 million Americans have some form of epilepsy
- 5% of epileptics are subject to the phenomena of Photosensitive epilepsy (125,000)
- Most of these 125K fall into the age range of 8-20 years - This eliminates many of the potential encounters
- Most of these are the female - This further reduces the population base
- The phenomenon is strobe rate specific, color frequency specific, as well as field of view specific and other factors play into it - This further reduces the probability of an episode.
- The Gladius Flashlight is strobing at a rate below the optimal range of 15-20 for this phenomena although other sources indicate lower rates can trigger this response - This further reduces the probability of an event. The probably of it happening are much higher from the same subject watching T.V. or playing video games. Natural light sources are just as likely to trigger seizures in a photosensitive individual as artificial ones. For example, sunlight shining off water or through the leaves of trees, or rapidly flickering as a person travels past railings, can trigger seizures.
Should something occur, recommended procedures include but are not limited to:
Stay calm. Help, but don't force, the person to lie down on his or her side, preferably on a soft surface, and place something soft under the person's head. Take the person's glasses or backpack off and loosen any tight clothing near the neck. Don't restrain or hold the person.
Do not put your fingers in the mouth or worry about the tongue.
Move objects, especially sharp or hard ones, away from the person. Stay with the person or make sure another friend or trusted person stays with him or her. Talk with the person in a calm, reassuring way after the seizure is over. Observe the event and be able to describe what happened before, during, and after the seizure.
When the shaking stops put them in the "recovery" position (laying on left side); Reassure and expect them to be very confused, they will likely have been incontinent of at least urine, they may have vomited.
They may be paralyzed on one side of the body - this usually resolves (Called Todd's paralysis) but beware the first thing that happened to them is they dropped completely unprotected to the ground and could have head injuries or could have neck injuries.
Bring up a tactical medic or tactical physician, or call an EMS unit by dialing 911 in most areas.
• The Gladius™ is not a toy and should not be treated like one.
• Keep Gladius away from children.
• The illuminated LED will generate heat; do not hold bezel or lens of an activated Gladius against any portion of the human body.
• Do not stare directly into the LED; momentary blindness and/or eye damage could result.
• Use caution when using the light as it can cause momentary blindness and/or disorientation within the subject and surrounding individuals.
