wattage of the bulb
When we choose a lamp, we always pay attention to the wattage of the bulb. We think that the higher the wattage, the brighter the lamp. Indeed, this statement is correct for the same type of lamps, but with the popularity of energy-saving lamps and LED lamps, this statement has slowly decreased.
 
The higher the wattage, the more power is consumed and the more electricity is consumed. With the same brightness, incandescent lamps consume about 7 times more power than LED lamps. That is to say, low-power LED lamps can reach the brightness of high-power incandescent lamps, so LED lamps are more energy-saving. Under the premise of the same brightness, LED lamps have the lowest wattage, followed by energy-saving lamps, and finally incandescent lamps. Although the cost of LEDs is relatively high, they have long lifespan, are energy-saving and environmentally friendly, and are more widely used.
 
To summarize the above point of view, when judging the brightness of a light bulb, the wattage is only a reference value. You need to look at its lumen value or luminous efficiency.
