Which is the best garden light source?

Most garden lights use ultra-bright white LEDs, and the time (life) for ultra-bright white LED luminous flux to reach 50% of the initial intensity at 20mA is less than 10,000h. That is to say, in many cases LED is not the best garden light source, unless it is a low-grade solar garden light with a service life of only 1-2 years, or a solar garden light below 1W. For solar garden lights above 1W, it is best to use three-color primary color high-efficiency energy-saving lamps. Some solar garden lights use 30-40 ultra-bright white LEDs with an input power of more than 2W. In this case, if a three-color primary color high-efficiency energy-saving lamp is used, the price is only 1/10 of the LED, and the luminous flux is 4 times the original. Now, 2-10W low-voltage DC three-color primary color high-efficiency energy-saving lamps have been successfully developed, and the life span can reach 6,000h. Therefore, low-power solar garden lights below 1W have the functions of adjusting the brightness and darkness and frequently switching on and off. Generally, LEDs should be used as light sources. However, when using ultra-bright white LEDs, pay attention to the luminous flux maintenance rate, otherwise it is easy to cause unnecessary quality accidents. For solar garden lights with higher power, it is more reasonable to use three-color primary color high-efficiency energy-saving lamps. Company: Shanghai CHZ Changhui Lighting Technology Co., Ltd.
