The brightness is quite good as marked 52LED. Processing not top quality finishings but relatively okay. 2 star deduction, because the light source can not be changed regardless of the version (was not in the item description visible), which means you need the complete recessed spotlights are changed when a defect (hopefully the product is then also available in a few years!). In addition, no description / installation instructions are enclosed. An expert does not need a manual however.
