I know that there are several different options. My friend uses LED lights for the garden. It's quite economical, but I found an even cooler option. Here in this article https://bestlightguide.com/best-solar-landscape-lights/ describes the solar lamps. You don't need to pay for electricity in the garden. It seems to me that this is the best option. I want to replace the lighting with such lamps completely. It's economical, environmentally friendly and not expensive.
