LED calculation: 100×0.95×0.85×0.9=72.68
Incandescent lamp calculation: 20×0.3×0.5=3
Therefore, in the same brightness, ordinary incandescent lamps are 24.23 times the power consumption of LED.
A. Life span
Incandescent lamp life is generally in 1800 hours, calculated in accordance with 10 hours of lighting per day for 180 days. The life span of LED lights is 70,000 hours, which is 7,000 days (about 20 years) according to 10 hours of lighting per day. If according to a 100 watt incandescent lamp average 5 yuan / one to calculate 10 years to change 20 bulbs (1000 yuan), a LED lamp head 15W for an average of 300 yuan. Save 700yuan and save a lot of time.
B. Power consumption
A 100W incandescent lamp consumes 0.1 degrees per hour × 0.8 yuan = 0.08 yuan.
100W incandescent = 10W LED per hour power consumption 0.01 degrees × 0.8 = 0.008 yuan.
Each hour can save 0.072 yuan × 10 hours / day × 365 days × 10 years = 2628 yuan (a bulb ten years of savings)
C. Maintenance costs
Incandescent lamps generally have a life span of 1800-3000 hours. On average, the bulb is changed once a year, and the replacement cost is 200 yuan / time for labor. The total cost for ten years is about 2,000 yuan.
As seen in points A, B, and C, the total savings of led lamp heads over 10 years of incandescent use are 700+2628+2000=5328yuan.
Environmental Protection
No ultraviolet and infrared light in the spectrum, no heat, no radiation, small glare, recyclable waste, no pollution does not contain mercury elements; cold light source, touchable, is a typical green lighting source.

Save budget: save money by one bulb:
A. Life span
The life span of energy-saving lamps is generally 1800 hours, calculated as 180 days according to 10 hours of lighting per day. The life span of LED lights is 70,000 hours, 7,000 days (20 years) according to 10 hours of lighting per day.
If you calculate an average of 8 yuan for an energy-saving lamp to change 40 bulbs in 20 years (320 yuan). An LED bulb 5W is an average of 60 yuan, saving 260yuan and a lot of time.
B. Power consumption
A 40W energy-saving lamp consumes 0.04 degrees per hour × 0.8 yuan = 0.032 yuan.
40W energy-saving lamps = 13W LED per hour power consumption 0.013 degrees × 0.8 = 0.0104 yuan.
Can save 0.0216 yuan per hour x 10 hours/day x 365 days = 78.84 yuan (one bulb savings per year)
C. Environmental protection
More environmentally friendly, no UV light is not harmful to human body.
