## Description

Product description Night Vision Hunting Support System: UF-2002D Infrared Illumination Equipment Compatibility: The UF-2002D is a hunting illuminator designed specifically for users equipped with night vision devices such as rifle scopes, binoculars, goggles, or spotting scopes. Lens Advantages: The 44mm Fresnel lens delivers high light transmission and uniform illumination. Its short focal length design enables illumination distances far exceeding standard lenses. Infrared Technology: Utilizes the most advanced Vcsel IR LED and the latest chip technology with a maximum range exceeding 1000 meters and a lifespan of 50,000 hours, featuring high efficiency and low heat generation. The difference between 850nm and 940nm lies in their performance characteristics 850nm offers a longer illumination range, higher brightness, and superior night vision capabilities, while 940nm provides reduced detail, shorter range, and lower visibility, resulting in better concealment. BE AWARE that not all infrared cameras & night vision scopes will pick up 940nm light. Check that the camera equipment you are using is compatible before you buy. Hunter's Ultimate Gear: UF-2002D Infrared Night vision Flashlight Smart Dimming Design: The 2002D dimmer switch features rotary control for stepless brightness adjustment (5%-90%). Quick-Change LED System: Features unique LED pill modules that can be swapped without tools (additional modules sold separately). Infrared illuminator Applications IR flashlights are primarily used for covert observation and locating prey. Their infrared light does not disturb animals and clearly displays the contours of heat sources. Examples: Coyotes, wild boars, deer, small mammals (hares), etc. 1605N T38 IR850nm Light 1605N T38 IR940nm Light 1605 T50 IR850nm Light 1605 IR850nm Light 1605 IR940nm Light 1605 T75 IR940nm Light

Review: UPDATED - Bad start, bad unit? - Updated: any adjustment to the intensity causes it to turn off, sometimes it just turns on for a few seconds. Not reliable. Original: Not a good start... Fresh batteries and it will not work. Has a red led that shows near intensity adjustment that illuminated for a few seconds Verified included battery and others i have. Will not appear on NVG (rated for 850 &940 IR)
Review: Don't bother! - Seemed like a good product. Worked well on the first charge. After that, the battery never took another charge. I tried to contact the seller to inquire about a replacement battery, but all I got was the bum's shuffle. I had to chat with an AI circle chat that blamed everything on desertcart. When I contacted desertcart, they checked out what I shared with them and made good on the return. Thanks desertcart! Next chapter: seller reached out and asked if I would try the light again with a different battery at no charge to me. I agreed and received a new light at no cost. First charge held strong for 3+ continuous hours plus another 3 a bit dimmer......not bad. Second charge performed the same. The light itself is a nice product. Out of the 4 brands I bought, this was the best light. I promised to reconsider my review. I didn't check to see if it's easier to contact the seller, but if it is, they deserve a 5 star! Nice recovery!

### ⭐ This is useless.
*by C***. on June 13, 2025*

It was barely visible even with a new 18650 battery. Save your money and don't bother with this one, my NVGs are in the 60,000 sensitivity and could barely pick up this light.
