What is the main difference between 940nm and 850nm IR light?

940nm IR light is completely invisible to the human eye, making it ideal for covert applications. 850nm IR light produces a very faint red glow that can be seen by the naked eye, especially in the dark.

What type of power supply do I need for this 5-meter reel?

You need a power supply that matches your selected voltage (12VDC or 24VDC) and is rated for at least 80 Watts to safely power the full 5-meter strip.

Achieve superior covert illumination with SuperLightingLED FSLSR-240-2835-940NM, a professional-grade 940nm IR LED strip light engineered for maximum performance. Unlike standard IR strips, this model features an ultra-dense layout of 240 SMD2835 LEDs per meter, delivering exceptionally high and uniform radiant intensity. This design eliminates dark spots and shadows, creating a seamless field of invisible infrared light perfect for high-resolution night vision security cameras, advanced machine vision systems, and scientific sensing applications. The 940nm wavelength is completely invisible to the human eye, ensuring discreet operation for any surveillance task. Choose from multiple waterproof ratings, PCB widths, and operating voltages to configure the ideal high-power IR LED solution for your project's specific demands.

Key Features

Ultra-High LED Density

Features 240 LEDs/m for a completely seamless, shadow-free beam of infrared light, eliminating hotspots seen in lower-density strips.

Covert 940nm Wavelength

Emits infrared light that is completely invisible to the human eye, making it ideal for discreet surveillance and security applications.

High Radiant Emittance

Utilizes powerful SMD2835 chips to deliver maximum radiant power, significantly enhancing the range and clarity of night vision cameras.

Fully Customizable

Can be cut at marked intervals (every 3 LEDs for 12V, 6 LEDs for 24V) for precise length adjustments to fit any installation.

Technical Highlights

This is the densest single-row LED IR 940nm strip in our catalog.
Adjacent LEDs are spaced only 4.17mm apart for flawless uniformity.
Due to high power consumption and the resulting heat generation, we recommend soldering and hardwiring the 940nm LEDs instead of using a DC adapter.
We also offer a red adhesive backing to improve heat dissipation.

Application Scenarios

Covert Security & Surveillance Enhance the night vision capabilities of security cameras without emitting any visible light. The 940nm wavelength provides powerful, invisible illumination for discreet monitoring of residential properties, commercial warehouses, and sensitive areas.

Machine Vision & Industrial Automation Provide a consistent and intense infrared light source for automated inspection systems, object sorting, and quality control. The high-density, uniform output ensures reliable performance for industrial sensors and cameras.

Night Vision Photography & Videography Create a powerful, portable IR floodlight for capturing clear images and videos in complete darkness. Ideal for wildlife observation, nocturnal research, and specialized cinematic effects where visible light is undesirable.

How to Install & Use This LED Strip

Ensure the power is off before starting the installation.
Clean the mounting surface thoroughly to remove dust and oils for optimal adhesion.
Measure and cut the strip at the designated copper cut lines if a shorter length is needed.
Peel the protective layer off the adhesive backing and firmly press the strip onto the clean surface.
Connect the 2-pin connector to a compatible 12V or 24V DC power supply. Ensure the voltage matches your strip.
Turn on the power to test. Note: The light is invisible to the naked eye; use a camera or night vision device to verify operation.

⚠ Precautions

Always use a power supply that matches the strip's voltage (12V or 24V) and can handle at least 80W.
While the strip is flexible, avoid sharp bends or folding it back on itself to prevent damage to the circuit.
For long-term reliability, consider installing the strip in an aluminum channel for better heat dissipation.
Ensure you select the correct waterproof IP rating for your installation environment (e.g., IP67/IP68 for outdoor use).
Be aware of how voltage drop works on longer runs to ensure consistent power.

Frequently Asked Questions

Q: Why is a high density of 240 LEDs/m important for an IR strip?

A:The high density eliminates dark spots between LEDs, providing a solid, uniform field of infrared light. This ensures that security cameras have even illumination across their entire field of view for clearer images.

Q: Can I see the light from this strip at all?

A:No. The 940nm wavelength is outside the visible spectrum of the human eye. You will need a digital camera, smartphone camera, or night vision device to see the illumination it provides.

Q: Is this IR LED strip suitable for outdoor installation?

A:Yes, but you must select the Waterproof IP67 or Underwater IP68 option during purchase. The standard IP20 version is for indoor, dry locations only.

Q: How does this single-row strip compare to a dual-row IR strip?

A:This single-row strip offers a more focused and narrower beam, ideal for targeted illumination or fitting into tight spaces. A dual-row strip provides wider coverage and higher total power output for illuminating larger areas.
