The total luminous flux or the entire light-output is showed in lumen. This size is the only comparison measurement to compare better to worse light sources. If you ask for the energy efficiency, then the ratio of lumens per watt is important. Look for the specified Data of the LED module, not only to the specified LED which is used. La eficiencia lumínica de un módulo LED se puede reducir considerablemente, debido a las lentes, reflectores de controladores LED ineficientes.

The candela value is only important when you speak about the brightness in the center of the emitted light beam and not about the efficient lighting of a complete area. An example of this is a punctual highlighting of goods in supermarkets.
