Description
The Holosun LS221 combines a visible green laser and an IR laser into a single coaxially aligned unit, simplifying zeroing and extending operational capability for both daylight and night vision use.
Whether you’re training in low light, conducting night operations with NVGs, or need rapid target acquisition in any environment, the Holosun LS221G delivers dual-spectrum capability without the complexity of separate adjustments. The coaxial design means that when you zero the visible green laser, your IR laser is automatically zeroed to the same point of impact, eliminating the need to adjust two independent systems and ensuring consistency across both visible and night vision applications.
Key Features
- Coaxial Dual Laser Design: Green visible laser and IR laser share the same optical axis, allowing synchronous windage and elevation adjustments that zero both lasers simultaneously—saving time and ensuring point-of-aim consistency across day and night operations
- Direct Green Laser Diode Technology: Utilizes a direct-emitting green laser diode instead of traditional DPSS technology, providing more stable output, better temperature performance, improved energy efficiency, and enhanced reliability in varying environmental conditions
- Extended Battery Life: Single CR123A battery provides up to 5000 hours of operation with four selectable power modes (visible low, visible high, IR low, IR high) controlled via rear-facing selector switch and included remote pressure switch
- Mil-Spec Construction: CNC-machined from 7075-T6 aluminum with MAO (Micro-Arc Oxidation) finish, IP67 waterproof rating, quick-detach Picatinny mount, and tactile 0.5 MOA click adjustments with ±60 MOA windage and elevation travel range
Why We Carry It
The Holosun LS221G represents a significant advancement in laser aiming technology through its coaxial design—a feature that addresses one of the most common frustrations among shooters who use dual-spectrum lasers. Unlike traditional dual laser systems, where visible and IR lasers must be zeroed independently (and can drift apart over time or when switching between firearms), the LS221G’s coaxial configuration means both lasers are aligned on the same axis and adjusted with a single set of controls. This allows you to zero the visible green laser during the day, then confidently switch to IR mode at night, knowing your point of impact remains consistent. The direct green laser diode technology also sets this unit apart from older DPSS-based systems, offering superior temperature stability across the full operating range of -40°F to 124°F and eliminating the power fluctuations and warm-up issues common with DPSS lasers.
Frequently Asked Questions
What’s the advantage of the coaxial design compared to separate laser adjustments?
The coaxial design means both the visible green and IR lasers share the same optical axis and are adjusted using the same windage and elevation controls. When you zero the visible laser, the IR laser is automatically zeroed to the same point of impact. This eliminates the need to separately adjust two independent laser systems and ensures consistent point-of-aim, whether you’re using visible or IR mode. Users particularly appreciate this when moving the device between different firearms, as you only need to re-zero once rather than adjusting both lasers separately.
How does the direct green laser diode compare to traditional DPSS green lasers?
Direct green laser diodes emit light directly from the semiconductor, while DPSS (Diode-Pumped Solid State) lasers use infrared light that’s converted to green through crystals. The direct diode design offers several advantages: more stable output across temperature extremes, better energy efficiency leading to longer battery life, faster response to power changes, and no warm-up period required. DPSS lasers can experience power fluctuations and beam instability when operating outside their optimal temperature range, whereas direct diode lasers maintain consistent performance from -40°F to 124°F.
Is this device compatible with night vision equipment, and what IR class is it?
Yes, the LS221G features a class 2M IR laser specifically designed for use with night vision devices and goggles. The IR laser operates at 0.1mW (low) or 0.7mW (high) output, providing a clear aiming reference through Generation 2 and Generation 3 night vision equipment. The device includes four selectable modes via the rear selector switch: visible low, visible high, IR low, and IR high, all accessible through the included remote pressure switch.
