Why is LED green product?
category | Voltage(V) | Power(V) | Lumens(LM) | luminous efficiency(LM/W) | Lifespan(Hours) |
Incandescent bulb | 240 | 45 | 470 | 15 | 1000 |
Compact fluorescent lamp(CFL) | 240 | 12 | 600 | 60 | 8000 |
LED spotlight | 240 | 5 | 450-500 | >80 | >50000 |
We can conclude from the above data: Under the same voltage and the same Lumens, incandescent bulb will cost 9 times power to LED. CFL is bette than incandescent bulb, but it also cost more than 2 times power than LED. But what matters the most is that LED can work for more than 50000 hours. However, the lifespan of CFL is only 8000hours and incandescent bulb is even as low as 1000hous.
