Lighting Knowledge

a.Power comparison table for LED bulb, compact fluorescent lamp, and incandescent lamp

	LED Bulb	Compact fluorescent lamp	Incandescent lamp
Rated power	7W	10W	100W
Luminous flux	560LM	513LM	565LM
Luminous efficacy	80LM/W	64.8LM/W	9.8LM/W
Service life	50,000hrs	5,000-7,000hrs	1,500hrs
Environment friendly(No HG)	Yes	No	No

2)Energy saving comparison for LED bulb, compact fluorescent lamp, and incandescent lamp

	LED Bulb	Compact fluorescent lamp	Incandescent lamp	Remark
With the same luminous flux	7W	10W	100W	1. Suppose that 10hrs for each lamp each day use 2. 0.16usd/kwh
Power consumption per hour	0.003kwh	0.007kwh	0.045kwh
50,000hrs Power consumption	150kwh	350kwh	2250kwh
50,000hrs Energy charge	24usd	56usd	360usd
Service life	50,000hrs	5,000hrs	1,500hrs
Change times in 3000hrs	1	10	33
Purchase cost	9usd	1.5usd	0.5usd
Total cost	33usd	57.5usd	360usd

3)Efficiency comparison for LED lights, compact fluorescent lamp, incandescent lamp and other light sources

	LED light	CFL/FL	Incandescent lamp	High pressure sodium lamp
Luminous efficacy	130lm/w	60lm/w	20lm/w	100lm/w
Power supply efficiency	95%	65%	/	50%
Lighting efficiency	85%	60%	60%	55%
Light fixture efficiency	90%	60%	60%	51%
Service life	50,000 Hr	1,800Hr	1,800Hr	6,000Hr

Then the actual efficiency of each lighting fixture is calculated out as below:
LED light: 130lm/w*95%*85%*90%=94.48lm/w
CFL/FL: 60lm/w*65%*60%*60%=14.04lm/w
Incandescent lamp: 20lm/w* 60%* 60%=7.2lm/w
High Pressure Sodium Lamp:100lm/w* 50%* 55%* 51%=14lm/w

It can be seen that, the actual efficiency of LED light is 6.7 times that of CFL/FL, 13 times that of incandescent lamp,6.7 times that of high pressure sodium lamp.
