So much of energy-saving performance is better

---

How much do you save energy when you switch to LED lighting from incandescent and fluorescent lamps?


Because LED lighting is a developing technology, it is constantly evolving. Although not be generalized because energy efficiency of the fluorescent lamp also has been improved more than ever, generally as compared to incandescent bulb 1/8 ~ 1/10 mm, energy saving of about 1/2 as compared with fluorescent lamps .
