How much is the power consumption of incandescent lamp? What about energy saving lamp? Other differences can also be put forward. Please choose the higher one


Incandescent lamp, 25W, 45W, 60W, 100W, energy-saving lamp, 9W, 11W, energy-saving lamp, as the name suggests, save energy, that is, save electricity! 25W incandescent lamp takes one hour, 9W energy-saving lamp can use about 3 hours! Energy-saving lamp in the process of using the corresponding less heat! Ordinary white incandescent lamp effect is about 10 lumens per watt



A 60 watt bulb consumes 10 degrees of electricity per month. Using energy-saving bulbs can save 80% of the original electricity consumption. What is the monthly electricity consumption of an energy-saving lamp?


10000w / 60W = 166.6h, 11W energy saving lamp is equivalent to 60W bulb, that is, saving 49w, 11W * 166.6h = 1.83 degrees
The monthly power consumption of an energy saving lamp is 1.83 degrees



How many times the power consumption of an incandescent lamp is that of an energy-saving lamp


Under the same illumination, the power consumption of incandescent lamps is about 4-5 times that of energy-saving lamps
