Awesome worklight that greatly diminished shadows when working on small items because the light source is all around. The arch is assembled in reference to the pictured diagram and the plates are all labeled in accordance with the diagram. I secured my sections together with epoxy though super glue can also be used. The foundations were designed with space to run the LED strip inside them to make the 180 degree turn inside so it is hidden and you are left with a clean look. I used these COB Dimmable LED lights here>>https://www.amazon.com/gp/product/B0BFDQMFPS/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1
