The LR140, 10m strip light roll is the brightest and highest output of our Ribbon Star Long Run series tape lights. With 140 LEDs per meter (42 per foot) and a constant current driving IC design, this entire 32.8ft strip can be powered from one end with consistent voltage and brightness from beginning to end. The top mounted 2835 LED chips generate less heat than older 3528 style while outputting high lumens with a longer lifespan. The CRI over 90 spec renders pure illumination of the lighting spectrum, making colors and displays more vibrant and true. A low power output of only 3.66 watts per foot and high lumen output up to 480 lumens per foot make this strip extremely efficient up to 131 lumens per watt. This light strip requires 24VDC power input, can be dimmed using low voltage PWM dimmer or dimmable power supply and can be cut and re-connected every 1.97" (5cm). See our 8mm connector options sold separately below as well as soldering guides for a more permanent connection.
