Light output

The light output indicates how many lumens a lamp produces per watt and is therefore indicated in lumens per watt (abbreviated with LM/W).
It is related to the luminous flux, which is measured in lumen, as well as with the power consumption in watts.

To put it simply, the light output stands for the efficiency of a lamp. The higher the value, the more efficiently a lamp converts the energy obtained in visible light.
Typical values ​​of the light output include:

• All use light lamp 12 LM/W
• Halogen lamp 18 LM/W
• Energy -saving lamp 66 LM/W
• Fluorescent lamp 104 LM/W
• LEDs 134 LM/W

The lamps can therefore be compared very well with the light output. Here it also becomes clear why incandescent lamps were banned due to their poor energy balance.

With a single watts of power, it only manages to generate 12 lumens, whereas an LED lamp with the same watt number generates a total of 134 lumens.

LEDs are therefore one of the most energy -saving and efficient lights.
