Kethvoz BT-881E Lux Light Meter is an industrial light candle meter used to measure lighting intensity in Lux / Footcandles. It widely used in interior design, research teaching, industrial inspection, LED light control, greenhouse, aquarium and indoor plants growing light balance. FYI: Light Illuminance is used to determine the brightness of a particular area. The illuminance indicates how much luminous flux falls into a defined area in lumens. The illuminance is a general measure of how much light output should be installed in a room.
