Nightstick NSP-4400B REACT Dual-Light LED Headlamp 650 Lumens

The Nightstick NSP-4400B REACT Dual-Light Headlamp delivers hands-free illumination with instant switching between flood and spot beam patterns. This professional-grade headlamp combines motion-activated controls with dual LED technology for tactical, industrial, and emergency applications.

What Makes This Different

The REACT technology sets this headlamp apart from standard models by allowing users to activate the light with simple head movements, eliminating the need to remove gloves or fumble for buttons in critical situations. The dual-light design provides both a focused spot beam for distance work and a wide flood beam for close-up tasks. Battery life extends up to 30 hours on low settings, significantly outperforming most tactical headlamps in its class.

Key Features

• REACT motion-activated switching - turn on/off with head movement
• Dual LED system: 650-lumen spot beam and 200-lumen flood light
• Multiple output modes: high, medium, low, and strobe functions
• Water-resistant IPX4 rating for all-weather reliability
• Adjustable elastic head strap with non-slip silicone strips
• 90-degree tilting light head for precise beam positioning
• Powered by 3 AAA batteries (included) with low battery indicator

Field testing demonstrates consistent performance across temperature ranges from -20°F to 120°F. The spot beam reaches effective distances of 200 meters, while the flood pattern covers a 120-degree spread for close-quarters work. Law enforcement, emergency responders, and industrial workers rely on the hands-free operation during equipment inspections, evidence collection, and maintenance tasks where manual light control proves impractical.
