Although the LED chip itself requires direct current to work properly, most home and commercial power systems provide alternating current. Therefore, when the LED lighting downlight is working, it needs to convert the alternating current into direct current through a power driver module.

Lumens are not directly equivalent to the intensity of lighting, but rather a measure of the amount of light emitted by a light source. In simple terms, lumens describe how much light a light source "emitted", but do not necessarily reflect the "brightness" of the light.

Generally speaking, when the LED bulb reaches the specified life span (such as 25,000 hours or 50,000 hours), its brightness will drop to about 70% of the initial brightness, and the LED bulb needs to be replaced at this time.

In the market, whether a lighting downlight is LED can be judged from the following aspects: 1. The appearance and design of the light source 2. The brightness and light effect of the lamp 3. The response time of the switch 4. The heat generation 5. The service life of the lamp 6. The color and light color of the lamp
