A lower Kelvin rating means the light is warmer, with more red and orange tones, while the higher the rating means the light is cooler with a blue tone. The two standard colors for white LED bulbs today are warm white (2700K) and daylight (5000K). Warm white gives off a nice cozy, calming and inviting ambivalence while daylight give off a more lively and invigorating light similar to the sun.While any bias light is better than no bias light during your Netflix and chill, not all are created equal when it comes to making the picture pop. If you want your TV to really shine, you’ll want the color temperature of the bias light to match the color temperature your TV or monitor manufacturer uses to back-light the display. Most TVs and monitors fall somewhere between 6000K and 6500K, so your best bet is to get one in that range.If you’re bias light is too warm, say 2700K, your TV will look out of place and the colors will look muddy. If you choose a cooler bias light, 7000K or more for example, the whites on your TV will look boring and gray.The original Luminoodle Bias Lighting is equipped with high quality, 6500K LED’s that provide up to 275 lumens of ambient light.
