For Your Information: * Lux is a measure of illuminance, the total amount of light that falls on a particular surface. And it can be the result of multiple light bulbs and even daylight mixed in. * Lumens is a measure of luminous flux, the total amount of light emitted in all directions. * The closer to the light source, the higher the lux reading. This is due to the dispersion of light as one moves away from the light source. ?Calibrated Luxometer?Strictly calibrated based on standard light with 2856K color temperature.155g lightweight and 173 x 52 x 30 mm compact design, you can always feel freely to take Kethvoz light meter with you anywhere to find the proper light level anytime. ?270° Rotable Light Sensor?Designed with rotating lux sensor, candela reader KE-881D supports 270° rotatable light measurement.
