A beautifully designed lamp to fully illuminate each key on your piano. Illuminance levels reach 300 lux on both sides. Unlike normal lamps, our exclusive optical design shines evenly across entire sheet music, both vertically and horizontally. Even in a space with uneven brightness you never have to worry about adjusting to the right light. PianoLight has a built-in ambient light sensor that automatically adjusts to the illumination level best suited to your environment.
