I installed them around my house and I have put a total of 13. Now my house lights up all night and you can comfortably walk around the garden at night.
I also used 4.5 watt LED bulbs (13*4.5w=58.5w) and it's like having a 60 watt old incandescent bulb on all night.
So it illuminates the whole house economically!

Very high-quality wall-mounted sconce. IP66, with thick rubber gasket, the lid is screwed with four stainless steel screws, internal clamp for power connection, securely fastened frame. Made entirely of anti-UV synthetic material. I bought it to replace very worn-out metal sconces and I am very impressed with the quality. And the cost is very reasonable.
[update] After one year, a hot summer and a harsh winter, it has no issues. The material still looks like new, nothing has passed through inside.
[update2] After 3 years, it has no issues. Flawless!
