What is the general brightness of LED bulbs?
A typical 40-watt incandescent bulb has a luminous efficiency of about 10 lumens per watt, so it can emit 400 lumens of light. At 220 volts, a 40-watt incandescent lamp has a luminous flux of 340 lumens.
Then let’s take an LED-P38 spotlight from Himax to illustrate the brightness and power saving of LED spotlights. LED-P38 spotlight: light flux (Lm): 500LM/450LM. Power: 7W, input voltage: AC90-265V, you can look at it, the light energy of LED-P38 spotlight is 500LM, which is suitable for ordinary incandescent lamps, while incandescent lamps need 40W power to reach, and led spotlights only Need 7W. According to the data, the power saving and photoelectric conversion rate of led spotlights is high.
