    to have the optimal performance of lighting regarding corals both lux and par meters are needed.
    lux ( horsepower ) behind par ( product ) based off cri ( torque ).

    cri (quality of the light)
    par (product -> type of the light)
    lux (power of the light)

    ;D

    cri is easy to find out when you have the wavelight
    lux is usually written on the info of the bulb
    par ... need measurement ::)
