This is a very big ferris wheel in Russian.There are two different led pixel lights used on this ferris wheel. 

On these arms are the big led pixels, and the middle disc is the small one.
In addition to the difference in size, these two led pixels are also different in the way of installation.
led pixel 1:100PCS/string, the middle with 100mm wire connected, each string with a pair of male/female waterproof connector; 
Moreover, the pixel light is fixed on the aluminum profile and does not require additional clip for installation.
led pixel 2: Each led pixel has a pair of male and female connector separately, you need connect each pixel light through the male/female connector; 
And this led pixel needs to go through the front hole, and then each  led pixel is secured with a clip.

Since this project is in Russia, all the products need to be used in low temperatures and outdoor environments.
The power supply is Mean Well waterproof HLG series;
Each LED pixel with glue covered;
The Controller is also putted in a waterproof box;
Connector and extension cables are also waterproof for outdoor use.
