Apogee offers two types of quantum sensors. The Full-spectrum Quantum Sensors feature an improved detector that provides accurate measurements under all light sources, including LEDs, right out of the box. The Original Quantum Sensor is less expensive and great for measuring all light sources except certain LED colors, where post-measurement correction factors need to be applied to achieve accurate readings.
