In the traditional lighting concept, the higher the wattage of the lamp, the brighter the lamp. Everyone likes the lamp with high wattage. But entering the era of LED lamp, the traditional way of choosing lighting has been changed. When choosing LED lamp, we should not only pay attention to the power of the lamp, but also to the brightness of the lamp to meet the requirements, as well as the energy-saving and environmental characteristics of the LED lamp.
1. LED:Light Emitting Diode
LED is a semiconductor device that converts electrical energy into light energy. LED luminaires are characterized by low power (wattage value) and high brightness (lumen value), so you should not buy LED luminaires based on power alone.
Power is not measured by brightness, but by power consumption. When choosing an LED lamp, you should check the brightness of the LED lamp, i.e. the light output, which is measured in lumen (Lm)..
2. Lumen (Lm)
The unit of luminous flux is lumen, short for lm.
Luminous flux: The rate at which light energy is emitted by a light source or the rate at which light flows (Flow arte), which is the basic quantity that explains the ability of a light source to emit light.
Simply put, lumen (LM) = the brightness that a candle's light shows up to one meter away.
3. Data comparison
Now on the market, LED luminaires should be marked with brightness (lumen value) on the packaging, which is an important parameter to measure LED lights.
For example: LED bulbs need only 8-12W to equal the brightness of 60W incandescent bulbs (450lm), which is why LED bulbs save energy. When buying incandescent lamps, consumers generally agree that the higher the power (wattage value), the brighter the incandescent lamp. However, when you buy LED lamps now, you should change your old ideas. In fact, the brightness and parameters of 60W incandescent lamp and 60W LED lamp are completely different.
4. Summary: Wattage is not equal to brightness
Many consumers only know power when they buy LED lamps. The basic reason is that they do not know that wattage measures not brightness, but power consumption. One of the greatest advantages of LED is its high light efficiency, which means power saving, which is more energy saving and environmental protection value for users.
Wattage(W)
Higher wattage does not mean brighter, it only means more expensive electricity
Lumen (lm)
The parameter that really represents the brightness of a bulb. The higher the lumen value, the brighter the bulb
In addition, the main parameters to be noticed in the purchase of LED lamps are: rated current; Rated voltage; Luminous flux; Light effect; Light intensity; Wavelength; Parameters such as color temperature.
