WULF FIIR 850nm IR Illuminator Torch – 38mm Ultra Wide Beam
The WULF FIIR 850nm IR Illuminator Torch with 38mm Ultra Wide Beam is designed to enhance the performance of compatible digital night vision riflescopes and observation equipment. Featuring a powerful 850nm infrared LED and adjustable beam focus, it provides additional illumination for clearer observation in low-light and complete darkness.
Its 38mm aspheric lens produces a clean, wide infrared beam, making it particularly useful for scanning open ground, woodland edges and larger areas where a narrow spotlight may restrict visibility. The adjustable focus allows users to switch between a broad flood beam and a more concentrated spot beam to suit the viewing distance and conditions.
The torch is also compatible with the HIKMICRO IR Torch Bracket, making it a practical accessory for users looking to upgrade the infrared illumination on a compatible HIKMICRO ALPEX digital night vision setup.

850nm Infrared Illumination
The WULF FIIR uses an 850nm infrared LED to provide illumination for digital night vision equipment.
Unlike a conventional visible-light torch, an IR illuminator emits infrared light that can be detected by compatible digital night vision sensors. This allows the device to produce a usable image when natural light is insufficient.
850nm illumination is popular because it generally provides stronger effective illumination than 940nm alternatives when used with the same class of digital night vision equipment.
However, an 850nm illuminator can produce a faint visible red glow at the emitter. Users prioritising minimum visible glow may prefer a suitable 940nm alternative.
The FIIR is intended for digital night vision equipment. It does not improve the performance of a thermal imaging sensor, which detects heat rather than reflected infrared light.
38mm Ultra Wide Beam & Adjustable Focus
The 38mm aspheric lens is designed to produce a clean infrared beam with useful coverage across the viewing area.
The adjustable focus provides flexibility for different observation distances and field conditions.
Flood Beam
A wider beam illuminates a larger area, helping users scan fields, woodland edges and nearby surroundings without constantly repositioning the torch.
Spot Beam
A narrower, more concentrated beam directs illumination towards a smaller area, which can improve effective illumination at greater distances.
The ability to adjust between these settings helps users match the torch's beam to the field of view of their digital night vision device.
Actual illumination range will depend on the digital sensor, atmospheric conditions, beam setting and surrounding environment.
HIKMICRO IR Torch Bracket Compatibility
The WULF FIIR 850nm 38mm Illuminator is compatible with the HIKMICRO IR Torch Bracket (HM-IRB-A), allowing it to be mounted alongside suitable HIKMICRO digital night vision riflescopes.
The torch has a nominal 25mm mounting body, matching the 25mm torch clamp used by the HIKMICRO bracket.
| Compatible bracket | HIKMICRO IR Torch Bracket (HM-IRB-A) |
| Torch mounting diameter | 25mm nominal |
| Bracket torch clamp | 25mm |
| Bracket scope tube fitting | 30mm |
| Suitable application | Compatible HIKMICRO ALPEX setups |
The bracket provides a convenient way to attach an external IR illuminator to a compatible 30mm scope tube.
Before purchasing, check that your riflescope has a suitable 30mm mounting section and that there is adequate clearance around the torch, objective lens and other accessories.
The HIKMICRO IR Torch Bracket is a separate accessory and is not included with the WULF FIIR torch unless specifically offered as part of a bundle.

Battery & Power Information
The WULF FIIR is a battery-powered infrared illuminator designed for use with compatible digital night vision equipment.
The exact battery type, battery inclusion and charger inclusion should be confirmed against the WULF packaging or supplier specification for SKU WU4008 before being advertised.
This is particularly important because infrared illuminators may be sold either as standalone torches or in packages containing rechargeable batteries and charging accessories.
Always use the battery type recommended by WULF and follow the manufacturer's charging and operating instructions.
850nm vs 940nm IR Illuminators
Choosing between 850nm and 940nm infrared illumination depends on the user's priorities and the performance of their digital night vision equipment.
| Feature | 850nm | 940nm |
|---|---|---|
| Effective illumination | Generally stronger | Generally lower |
| Visible emitter glow | Faint red glow possible | Less noticeable |
| Longer-range viewing | Often preferred | Depends on sensor sensitivity |
| Discreet observation | Moderate | Often preferred |
Choose 850nm when effective illumination and viewing distance are the main priorities.
Choose 940nm when reducing the visible glow from the illuminator is more important.
Actual results depend on the night vision sensor, lens, illumination power and operating conditions.
38mm vs 50mm IR Illuminators
The WULF FIIR range includes different lens sizes and wavelengths to suit different observation requirements.
38mm Ultra Wide Beam
A practical option for users who want broad illumination and flexibility when scanning an area. The 38mm lens is well suited to matching a wider field of view on compatible digital night vision equipment.
50mm Illuminators
Larger-lens alternatives may be better suited to users who prioritise concentrating illumination over longer distances, depending on the particular model and its beam adjustment range.
The best choice depends on your digital night vision device, typical observation distances and preferred balance between wide-area coverage and concentrated illumination.
