The soundscience halo 6 LED bias lighting kit™makes it easy to outfit your monitor with professional backlighting. Bias lighting adds a subtle white backlight to your monitor, reducing eye fatigue & increasing perceived image clarity. The color & brightness of the LEDs are carefully calibrated to achieve the optimal viewing experience & increase your monitor’s perceived contrast ratio – making blacks blacker & colors more vibrant. Simply attach the LED strip to the back of your monitor & insert the USB (Universal Serial Bus) plug into an open USB (Universal Serial Bus) port on your computer or powered USB (Universal Serial Bus) hub. The soundscience halo 6 LED bias lighting kit™ complements any monitor up to 24” in size.
