Indeed, it should be noted that not all LEDs have the same lighting power and that some of them alone can have a luminous flux equivalent to more than 500 LEDs less powerful.
The most efficient and economical light bulbs are now the LEDs, but they are not bought like a conventional incandescent bulb or even halogen. Here are some of our tips for making the right choice.
With incandescent bulbs and halogens, we speak had to deal with watts (W), since their luminous intensity depends on their power consumption. This is no longer the case with LEDs. For example, a 6W high performance LED illuminates as well as a 60W incandescent bulb or 46W halogen. The central LED information is the lumens (lm). Read more
