The traditional concept of lighting is that the higher the wattage of the lamp, the brighter the lamp and everyone prefers high wattage lamps. But entering the era of LED light fixtures has changed this traditional way of choosing lighting fixtures. When choosing LED light fixtures, you should not only focus on the power of the fixture, but also on whether the brightness of the fixture meets the requirements.
LED, Light Emitting Diode, efficiently converts electrical energy into light. LED lamps are characterised by low power (wattage) and high brightness (lumen value), so the choice to buy LED lamps should not be based on power alone.
Lumen, a physical unit describing luminous flux, is physically interpreted as the total emitted luminous flux produced by one candle (cd, Candela, a unit of luminous intensity equivalent to the luminous intensity of an ordinary candle) in one stereoscopic angle.
LED lamps on the market nowadays are marked with a brightness (lumen value), which is an important parameter for measuring LED lamps. The following table is for your reference.
LED ceiling light only need 8 to 12W to be equivalent to the brightness of a 60W incandescent bulb (450lm), which is why LED lights are energy efficient. So for LED lamps, it is important to focus not only on the power of the lamp but also on the lumen value of the lamp.
The lumen value of a light fixture divided by the wattage of the fixture is the luminous efficiency of the fixture: lumens per watt (LM/W). The higher the value, the brighter the different lamps are for the same power consumption, i.e. the lower the power input of a lamp with high luminous efficiency for the same brightness, the more energy efficient it is.
One of the main advantages of LED lighting is its high luminous efficiency, which means that it saves electricity, which is of more energy-saving and environmental value to the user. Wattage measures not brightness, but power consumption. When choosing an LED light fixture, you should check the brightness of the LED light fixture, i.e. the light output, which is measured in lumen (Lm). So don't ignore the true unit of brightness, lumen, when buying LED light because of the limited wattage.
