How about Ke Mei light bulbs?

Ke Mei bulbs have higher light efficiency, so they save more electricity.

Led has higher light efficiency, so it saves more electricity. However, at present, most low-end led lighting lamps have the following phenomena: LEDs are mostly point light sources or point light source arrays. As the main floodlighting lamps, the vision is not as comfortable as fluorescent lamps. However, the price of high-end lamps such as high-end lamp beads and diffuse scattering plates is high, so their cost performance is reduced. Moreover, once the led lamp is damaged, the maintenance technology is high, so the maintenance cost is also high. Personally, I feel that led lamp is more suitable as background light for a long time. Kitchen, bathroom and foyer with low lighting requirements in a small space can also be used.
