EVOLVA FUTURE TECHNOLOGY T20 IR 850nm IR Light Illuminator Infrared Led Flashlight 38mm Lens IR Torch for Long Rang Night Vision Scope Hunting (Battery and Charger Package)

I have both the Evolva T20 and T38 and recommend them highly and you won't go wrong with either. Compared to an Armasight XLR 850 which costs 2-3 times as much these are not as polished or of the same build quality as the Armasight but these units are just as bright and illuminate almost as well. Excellent Bang for the Buck.The T20 and T38 are basically the same size and both appear to have the same 38mm front lens, Same IR LED Chip, and function the same (Cycle the power button Once to turn on, twice rapidly to switch from Low, Medium and High settings, with the Illuminator Flashing when the battery is Low). Both can also be rail mounted using a standard 1" scope ring.Comments are for Both T20 and T38 unless otherwise notedPRO's:- Extremely Bright Illumination- This light will make a Gen I NV Device look impressive!- Long Range- When focused it can throw a beam 200+ yards (it made my Gen 1 1x Monocular very usable at 75+ yards)- Wide Angle Suitable for 40 degree FOV monoculars.- Tactical Look & Grip (T38 Only)- Works very well even when using / focusing with one hand Much better for hand held use than the T20.CON's:- Can be Too Bright*- When used with Gen II or especially Gen III it can be almost too bright even on the Lowest Setting (wish it had a 4th Lower setting like the Armasight)- Lens assembly is loose* - This is Not a big issue but if Mounted with a Scope and focused for distance between the fully in and fully extended positions the lens barrel has a significant amount of play in it which will allow the beam to shift, with the fully extended position being slightly beyond the tightest focus of the beam (which may or may not be an issue depending on your use)- Does not appear to be Water Tight - Should be water resistant, but with the lens wiggle when extended I suspect this could be an issue.- Uses rechargeable 18650 Battery - To get best use of the unit you will need to order spare batteries and charger (I'm listing this as a negative but the truth is that I've not seen any illuminator of this type that doesn't use the 18650's).Other Notes:- *Although these are very comparable to the Higher end ($$$) illuminators the Armasight 850 has no wiggle in the lens (ie rock solid beam), and has a 4th lower power setting and a rotary tail switch making it more flexible (especially for Gen III) and user friendly. I'm not selling the Armasight, just pointing out what the extra $80-$100 gets you.- Beam Differences between the T20 and T38 - The T20 does have a more uniform beam due to the reflector in the lens assembly, however the same reflector also makes the light more readily visible from the side (light scatter).- Rat Tail Caps / Switches - End caps are not interchangeable between the units, so if you need rat tails they will not interchange between the two. Additionally the Rat Tails have two switches built into them. One that mimics the function of the standard tail cap switch, and a second momentary type switch so you be passive and use the light momentarily.- Hard Mounting - Both the T20 and T38 can be rail mounted using a standard 1" scope ring with the maximum diameter of the lens assembly being approx 42-44mm.- Visible Light - For those who are new to Night Vision or Not Familiar with InfraRed light. "IR" is light between approx. 800nm and 1mm wavelength. What this means for Non Science geeks is that most IR illuminators, which operate at approx. 850nm will be visible to the naked eye as a very deep red light which is Normal. This is largely due to the fact that LED's give off light over a range of frequencies with an 850nm LED producing light from approx. 700nm to 950nm with most of the light centered at 850nm, which is an Optimal frequency for most Night Vision image tubes. Incidentally Thermal Imaging devices also see in the IR spectrum but at the opposite end as standard night vision which includes thermal / heat radiation.

Did not work at all. Fully charged batteries, then turned it on. There was a very faint red glow when I peered down the lens, but no light was coming out. I returned it to Amazon.

This is my first IR torch, it works great and I am not disappointed in it's performance. It is just what I was expecting and more. I converted a 12mp point and shoot camera by taking the IR filter out and using this light it is impressive how far and how tight the beam can be adjusted. It is not like a normal light where the beam looks washed out at a distance, this thing holds a nice tight square pattern beam if adjusted for range. It also can be adjust for nice flood/area beam. I plan to eventually use it with an IR scope and I think it will work great. If anything changes with how i feel about this light I will update this review.

I purchased this to use with my ATN 4k and it is nowhere near as good as the factory ATN light. I now use it with my gen 3 NVG goggles and its OK but if I want a cleaner image I use the atn light. I would return and buy a better product but unfortunately I waited too long.

Paired it up with the ATN X-Sight 4K Pro scope and it's amazing what you can see out in the dark. Great for pesting jobs and hog hunting.

Very weak. Does not have more than 20 feet range.

I use this with my ir camcorder and it works perfectly

Received on time. Charged the battery in a couple of hours. Used it last night on hog hunt. Total run time was about 2 hours total out of 3 hour hunt. Easy adjustment on wide and narrow beam. Worked well at about 50 yards. Weak out much further, even on zoom. Happy overall especially with this light weight unit.
