What lamp is the most energy-saving now? LED lights are too expensive. Are there any new products that can be replaced?

Undoubtedly, LED lamp is the most energy-saving and incandescent lamp is the cheapest, but the light efficiency of LED is about 10 times that of incandescent lamp, which means that the traditional 60-watt light bulb only needs 10 watt LED, which obviously saves electricity. The life of LED is more than 100 times that of incandescent lamp, that is to say, only the incandescent bulb LED with 100 will be broken, so it is most cost-effective to consider LED comprehensively. In addition, LED has not been popularized on a large scale (mainly because people like you will find the unit price expensive for the first time). It is the latest technology, and there is no more advanced lighting technology than it.
