Product Information

Dual Row 940nm, 850nm infrared LED strip light with 600 pcs high bright 5050SMD LED chips, 15mm wide PCB board, suitable for High bright IR LED lighting project. 

The 940nm, 850nm IR LED strips emit the light that is virtually invisible to the naked eye, these IR LED lights can be dimmed the brightness via using the LED dimmer controller. 

DC12V input, every 6 LEDs can be cut (50mm/2"); DC24V input, every 12 LEDs can be cut (100mm/4"), easy to cut and won't damage the LED strip light. With 3M adhesive backing tape, you can install the lights anywhere you need.

Widely used for many commercial applications, such as IR night vision, infrared photography surveillance lighting, and infrared automatic inspection and detection light. 

We offer LRS-200-12 or LRS-200-24 power supply in the kit for sample testing (come with AC plug).

Industrial-grade IR output - Perfect for long-range night vision

We integrated the 940nm version of this dual-row strip into a machine vision project for a manufacturing line. The light uniformity is excellent; the double-row configuration ensures there are no dark spots or "banding" in the high-speed camera captures. Since 940nm is completely invisible to the human eye, it allows us to monitor the process 24/7 without creating light pollution in the workspace. The build quality of the PCB is surprisingly robust, easily handling the high current required for 144W. The adhesive is strong, but given the weight and heat of a dual-row strip, I recommend using mounting clips for permanent installs. This is a professional-grade component that delivers exactly what the specifications promise. Highly satisfied with the performance and the fast shipping!

LED Strip Light Guide

Common questions about this type of product, answered against this model’s own options. For full figures see the specification above or the spec sheet for this model.

What voltage does this LED strip light run on?
This model is offered in 24VDC · 12VDC. Lower voltage means a shorter run per feed: at 12 V feed power roughly every 5 m, at 24 V roughly every 10 m. Longer runs get power injected at both ends. Connecting to the power supply
Which waterproof rating should I choose?
Available on this model: Underwater IP68 - Adhesive Back · Waterproof IP67 - Adhesive Back · Surface Glued IP65 - Adhesive Back · Non-Waterproof IP20 - Adhesive Back. IP20 is for dry indoor use, IP65 handles splashes, IP67 suits outdoor and wet areas, IP68 is for continuous submersion. Choosing a waterproof rating
Can I cut it to length?
Yes. Cut only on the marked cut lines between the copper pads — the cut interval for this model is on its spec sheet. Rejoin with solder or a solderless connector. Cutting LED strip lights · we can also cut to length and fit your connector before shipping: custom LED strip light assembly.
What size power supply do I need?
Take the watts per metre from the specification above, multiply by the length you are running, then add about 25% headroom. Power calculation guide · Choosing a power supply
