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. Bir LED modülünün ışık verimliliği büyük ölçüde azaltılabilir, lensler yüzünden, verimsiz LED sürücülerin reflektörleri.
