These single-color LED light modules provide consistent illumination for channel letters, sign lighting, under-cabinet lighting, store window lighting, and display case lighting. Modules are available in packs of 25 or 100, stranded together upon purchase. Strands are wired together with 4.05" spacing between each module (up to 25 modules per strand). The 20-gauge wire is polarity sensitive; black striped wire is positive, and white wire is negative. Each LED module has 3 LEDs and emits up to 57 lumens. LEDs emit a wide 120° beam pattern that is best suited for illuminating up to 9" wide channel letters that are as shallow as 3". The narrow PVC module is injection molded with a 0.15" screw hole for mounting in extreme cold or heat. Double-sided 3M adhesive foam tape is also included for secure mounting. The waterproof module has 12V DC operation and is designed to last 40,000 hours.
