Lumens are a measurement of how much light is generated – or brightness – each lumen emits approximately the same amount of light as one candle. Kelvin represents the "color" (which is based on the temperature) of the light. Bioluz LEDs are manufactured so that our 2700K (2700 Kelvin) bulbs are nearly identical in color to incandescent bulbs. Our 3000K bulbs are designed to match halogen bulbs. We’ve found that bulbs which are 4-5000K generate a bluish tint on objects (like at a hospital or office building) and are not as comforting in a home. Many brands sell and market higher Kelvin bulbs with lower lumens to make them "appear" brighter. Bioluz LED manufactures the correct color bulbs with exceptionally bright, energy efficient LEDs, so you get the color and brightness you're accustomed to without the harsh effect of higher color temperatures.
