Frequently Asked Questions

An IR (Infrared) illuminator is a device that emits infrared light, which is invisible to the human eye but can be detected by night-vision equipment. It provides the necessary light source that night-vision devices can amplify to create visible images in dark environments.

IR flashlights are specifically designed handheld devices that emit infrared light for use with night-vision goggles, scopes, and cameras. They're essential for hunting, law enforcement, surveillance, and tactical applications where ambient light is insufficient.

850nm (Nanometers) infrared light:

• Emits a faint red glow visible to the human eye
• Provides maximum illumination range and brightness
• Best compatibility with all generations of night-vision devices (Gen 1, 2, and 3)
• Ideal for hunting and tactical applications

940nm infrared light:

• Completely invisible to the human eye — truly stealth operation
• Slightly reduced range compared to 850nm (approximately 10-15% less)
• Perfect for covert surveillance and law enforcement operations
• Recommended when absolute discretion is required

For most hunting and recreational applications, 850nm is recommended due to its superior range and compatibility.

Consider these key factors when selecting an IR illuminator:

• Night-Vision Generation: Gen 1 devices work well with lower-power illuminators (up to 100mW), Gen 2 benefits from medium-power (100-300mW), and Gen 3 can leverage high-power options (300mW+).
• Wavelength: Choose 850nm for maximum range or 940nm for complete stealth.
• Beam Angle: Narrow beams (15-30°) for long-range, wide beams (60-90°) for close-range coverage.
• Application: Hunting typically uses 850nm, surveillance uses 940nm.

The effective illumination range depends on several factors including ambient conditions, moon phase, and night-vision device sensitivity. As general guidelines:

• IR850 Pro: Effective range of 100-200 meters with Gen 1 devices, up to 300+ meters with Gen 2/3
• IR850 Supernova: Extended range of 150-250 meters with Gen 1, 400+ meters with Gen 2/3 devices

Both models feature adjustable focus to optimize beam pattern for your specific needs — narrow focus for distance, wider beam for closer range.

Our IR flashlights are compatible with all generations of night-vision devices:

• Gen 1: Entry-level night-vision scopes, goggles, and cameras
• Gen 2: Military and law-enforcement grade devices
• Gen 3: Advanced military-grade night-vision equipment
• Digital Night Vision: Many consumer digital night-vision cameras and scopes

Dereelight models are engineered for broad compatibility with major night-vision brands and are a popular choice for ATN, SIONYX, and similar devices.
