Holosun LS420G Multi‑Function Laser & Light Module – Green and IR with 600 lm White Light
The Holosun LS420G is a multi‑function laser‑and‑light tactical module designed for sport shooters, hunters, and outdoor professionals who need integrated visible and infrared aiming plus illumination in one compact unit. This advanced module combines a high‑visibility green laser (620 nm), an infrared laser pointer, an IR illuminator, and a 600‑lumen LED white light, all coaxially aligned into a single robust housing. The result is a streamlined aiming and lighting system that lets you maintain a single zero while switching between modes, making it ideal for dynamic close‑and‑medium‑range scenarios, low‑light training, and night‑oriented work in European conditions.
Key Advantages
- Dual‑wavelength aiming: A bright 620 nm green laser for daylight and low‑light use, paired with an 830 nm IR laser that works with night‑vision devices, giving you flexible aiming options day or night.
- Coaxial IR illuminator: The 830 nm IR flashlight integrates with the IR laser, with adjustable focus from 95 to 210 mrad, so you can smoothly scale the beam angle for target identification or wider area illumination.
- Integrated 600‑lumen LED light: A 6000 K‑temperature white‑light LED (up to 600 lumen output) supports room clearing, path lighting, and short‑range work, while remaining eye‑safe when used as intended.
- Rugged, IP67‑rated housing: The body is machined from 7075‑T6 aircraft‑grade aluminium with an anodised, MAO‑coated finish, rated IP67 for dust‑ and moisture‑resistance and able to withstand 1000 G shock, ensuring reliable performance in wet, dusty, or cold‑weather environments.
- Multiple power options: The LS420G runs on two CR123A cells or a single 18650 rechargeable battery, with a covert charging port and a remote‑switch cable included, increasing field endurance and reducing the need for frequent battery swaps.
- Quick‑release mounting and micro‑dot compatibility: The unit mounts directly to a Weaver/Picatinny rail with a quick‑detach base, while its top allows co‑mounting a Holosun Micro‑style red‑dot sight, creating a compact, multi‑layer aiming system in a small footprint.
- Long operational life: Powered from two CR123A cells, the LS420G delivers up to about 5000 hours of cumulative use depending on mode, which is ideal for extended training blocks, multi‑stage competitions, or field deployments without frequent battery changes.

Frequently Asked Questions
What is the main advantage of the Holosun LS420G over a standalone laser or light?
The LS420G unifies a visible green laser, an IR laser pointer, an IR illuminator, and a 600‑lumen white‑light LED into one precisely aligned module. This means you only need one zero to work in all modes, while still having broad flexibility: visible laser for close‑range aiming and signaling, IR for covert night‑vision‑assisted work, and white light for clearing or general illumination.
How precise is the adjustment on the LS420G?
The module is fitted with tactile windage and elevation dials offering 0.5 MOA per click, with a full ±50 MOA travel range on both axes. This allows fine‑tuning to match your zero across different distances or optics, including any micro‑red‑dot that sits on top of the module.
Is the LS420G safe to use with common night‑vision devices?
Yes: the 830 nm IR laser and IR illuminator are class‑rated to work with standard night‑vision systems and are designed to be eye‑safe at prescribed distances when used correctly. The white‑light LED is also built to be eye‑safe, making this module suitable for low‑light drills and night‑oriented field use.
How long will the batteries last in practical use?
When powered by two CR123A cells, the LS420G can provide up to roughly 5000 hours of total operation, depending on brightness level, IR‑vs‑visible usage, and environmental conditions. Using an 18650 cell and a 4‑pin in‑device charging port further extends field endurance with rechargeable power.
Why does the LS420G use 7075‑T6 aluminium, and how does that help in the field?
7075‑T6 is an aerospace‑grade alloy known for its strength‑to‑weight ratio and resistance to harsh conditions. In the LS420G this material, paired with an MAO‑coated finish and IP67‑rated sealing, lets the module resist shocks, extremes of temperature, and moisture, which is especially useful for European‑climate sport‑shooting, hunting, and outdoor‑professional applications.
Can I mount a red‑dot sight directly on top of the LS420G?
Yes: the LS420G features a top‑mounting platform specifically designed for Holosun Micro‑style red‑dot sights (e.g., EPS/Micro‑red‑dot pattern). This turns the module into a complete multi‑layer aiming system with a collimator sight resting directly above the laser‑and‑light package, saving rail space and maintaining a clean, compact profile.
How is the LS420G mounted, and how easy is it to remove in the field?
The module uses a Weaver/Picatinny quick‑detach base, so you can clamp it firmly onto a rail and still remove or reposition it quickly when needed. The integrated far‑contact‑switch cable included in the set lets you place a remote switch on the grip, giving you fingertip control over laser and light modes without having to touch the unit itself.
If you are looking for a compact, multi‑mode laser‑and‑light module that combines visible and IR aiming with a bright white‑light source, consider the Holosun LS420G.
