Holosun IRIS GR4 4 Channel Laser Light Module – Green Dot, IR Pointer, 1000 Lumen LED

Holosun IRIS‑GR4 Tactical Laser Module with Green Laser, IR Pointer, IR Illuminator & White Light

Holosun IRIS‑GR4 is a compact, multi‑channel tactical laser and light module engineered for sport shooters and professional outdoor users who require combined illumination and laser guidance. The IRIS‑GR4 integrates four independent channels: an IR VCSEL illuminator, an IR laser pointer, a visible green laser, and a high‑output white LED light. All channels are optimised for reliability and ease of use, making this unit ideal for day‑to‑day training, low‑light sport applications, and professional field work across European climates.

Compared with earlier Holosun laser units, the IRIS‑GR4 is 43% lighter, 29% lower, and 28% narrower, thanks to a rugged 7075‑T‑6 aluminium housing with hard‑anodized finish. The compact profile minimises bulk on rail‑mounted systems while retaining full IPX8‑grade waterproofing and 1000G‑level impact resistance. Holosun’s updated mode selector on the rear panel and integrated three‑button remote provide fast, intuitive access to each function, with priority‑switch logic to bring the visible green laser online instantly when needed. Running on a common 18650 rechargeable cell, the IRIS‑GR4 delivers extended operating time suitable for demanding sessions, from cold‑weather durability (-20 °C to +51 °C operation, storage -40 °C to +70 °C) to intense urban‑style drills.

Optical and laser performance

The IRIS‑GR4’s visible green laser (class 3R) projects a bright, clear dot at 1 mW (low) or 5 mW (high) output, ideal for daylight‑visible aiming or quick target marking without exposing you to high‑power‑device restrictions in many European jurisdictions. Integrated IR laser pointer (class 1, 0.1 / 0.7 mW) and 60 mW VCSEL IR illuminator (class 1) work with night‑vision gear to support covert observation and low‑light guidance, while remaining eye‑safe within normal use. The white LED channel outputs 1000 lumens at 25,000 candela, delivering powerful, focused flood lighting for navigation, object identification, and area illumination in the dark.

Technology and reliability

Precision is built into the system with a dual‑axis windage/elevation turret, 0.5 MOA per click, and ±50 MOA total travel, allowing fine‑tuning of the laser point of impact once mounted on rail platforms. The housing meets IPX8 waterproofing and withstands 1000G shocks, ensuring performance after drops, bumps, and rough handling. The IRIS‑GR4’s thermal operating range of ‑20 °C to +51 °C and storage range of ‑40 °C to +70 °C make it suitable for the full spectrum of European conditions, from alpine environments to hot‑weather training grounds.
Battery and power: A standard 18650 Li‑ion cell powers all channels, simplifying logistics and supporting long‑term deployment. The module includes a rear‑mounted mode selector, built‑in activation buttons, and a three‑button remote switch cable for tactical‑style activation without touching the unit.

Practical use in Europe

For European sport shooters and professionals, the IRIS‑GR4 excels in scenarios where a single compact rail‑mounted unit must replace multiple separate devices:

• Sport shooting and training: fast green‑laser engagement drills, low‑light stage work, and IR‑aided night practice with compatible optics.
• Outdoor and field applications: navigation in darkness, temporary object marking, and low‑profile light source for non‑conflict‑oriented tasks.
  The compact 107 × 58 × 36 mm footprint and 241 g weight keep overall system balance light and ergonomic, while the wide temperature range and robust 7075‑T6 construction ensure reliability in rain, snow, or heat.

Frequently Asked Questions

What is the difference between the IR pointer and the visible green laser on the Holosun IRIS‑GR4?
The IR laser pointer (class 1, 0.1 / 0.7 mW) is designed for use with night‑vision devices and remains invisible to the naked eye, making it suitable for low‑visibility, covert‑style guidance. The visible green laser (class 3R, 1 / 5 mW) is primarily intended for daylight‑ or low‑light‑visible aiming and target marking, with a clearly visible green dot that is easy to pick up quickly in dynamic drills. Both channels are eye‑safe within their respective ranges under normal use, but the visible green laser is more suitable for sport‑shooting and training‑related applications where a visible dot is required.

How many operating channels does the Holosun IRIS‑GR4 have, and what can each one do?
The Holosun IRIS‑GR4 features four independent channels:

• A 60 mW VCSEL IR illuminator (class 1) for night‑vision‑compatible area illumination.
• An IR laser pointer (class 1, 0.1 / 0.7 mW) for covert laser‑point guidance in darkness.
• A green visible laser (class 3R, 1 / 5 mW) for quick target marking and visible‑spectrum aiming.
• A 1000‑lumen white LED light (25,000 candela) for general area illumination and close‑range tasks.
  All four channels can be activated via the rear selector switch and/or the included three‑button remote, letting you switch between IR‑only, visible‑laser‑only, or mixed‑light scenarios as needed for training and field use.

Is the Holosun IRIS‑GR4 suitable for sport shooting and professional field use in Europe?
Yes, the Holosun IRIS‑GR4 is well adapted for European sport shooting, law‑enforcement‑style training, and other professional‑oriented outdoor applications where a compact, multi‑function laser‑light module is required. The four‑channel design lets you combine IR‑aided night‑vision work, visible green‑laser drills, and high‑intensity white‑light illumination in one rugged unit. With its IPX8 rating, 1000G‑shock resistance, 0.5 MOA adjustments, and wide operating‑temperature range (-20 °C to +51 °C), the IRIS‑GR4 remains reliable in rain, cold, or heat and is suitable for use on various rail‑ready platforms in Europe.

Can the Holosun IRIS‑GR4 be powered by common batteries, and how long do they last?
The Holosun IRIS‑GR4 is powered by a standard 18650 Li‑ion rechargeable battery, which is widely available and easy to replace or recharge, making logistics simple for European users. Runtime varies by channel and intensity setting, but the efficient LED and low‑power‑laser design allow for extended operation suitable for training sessions and field deployments. For exact runtime, check the manufacturer’s notes for each mode, since IR and visible‑laser channels typically consume less power than the 1000‑lumen white‑light output.

Where can I buy the Holosun IRIS‑GR4 in the EU, and what warranty does it include?
