For example, a 10-watt LED spotlight may output 800-1000 lumens, while a traditional halogen lamp of the same power can only output about 400-500 lumens. In other words, LED lamps are more energy-efficient and have higher light output than traditional light sources.

The beam angle of LED spotlights is generally between 10 degrees and 60 degrees. The beam angle design within this range can meet various concentrated lighting needs. Narrow beam LED spotlights have very small beam angles, usually between 10 degrees and 20 degrees, and are suitable for concentrated lighting at a long distance.

Luminous efficacy (lm/W) = Luminous flux (lm) ÷ Power (W) For example, if the luminous flux of an LED bulb is 800 lumens and the power is 8 watts, its luminous efficacy is: Luminous efficacy = 800 lm ÷ 8 W = 100 lm/W

Integrated driver power supply: Many modern LED track lights use an integrated driver power supply design, that is, the driver power supply is integrated into the lamp head or lamp body, so that consumers do not need an additional transformer or external power supply when installing and using.

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.

Unlike recessed downlights, the installation method of flat downlights usually does not require the light fixture to be embedded in the ceiling, but to be installed directly on the ceiling surface. This design makes the flat-bottom downlight easy to install and maintain, and is suitable for simpler space designs.

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.

If the circuit board or driver chip inside the LED lamp is exposed to the outside and is affected by moisture, dust or other contaminants, it may cause short circuit or damage to the electrical components. Failure of the driver circuit may cause excessive or unstable current, thus burning out the LED light source.

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
