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)



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