It illuminates as if it were decorative...
Anyone who wants to illuminate a spot only with these bulbs should simply not buy it.
And the other problem is that the bulbs are not 16 but 10

The lights are very nice. The problem is that they need a lot of sun (8 hours in the sun and 4 in the power) to light up for 8 continuous hours ... if there is no sun, don't expect much, but the good thing is that they have a power supply with USB. If you don't have sun, you can charge them with a cable (not provided) from old cell phones. My advice after installing them ... put them somewhere where it will be easy for you to remove them when you put them in the power. Another good thing is that it has a remote control and you can adjust the intensity, and various effects.

I received them yesterday and installed them today. So far, they seem to have nice lighting and good quality. However, I am giving them 3 stars because the bulbs are 10 and not 16 as stated in the product description.
