The LED spotlights make really bright and pleasant light. Before buying, however, it should be checked if the supplied cables are suitable for the planned installation situation. I have the radiator sunk into my patio this, what can be done because of the outside diameter of 50mm well with standard tools (Forstner bit). The springs keep the spotlight also in compliance with the installation diameter not really fixed (what with me because of the recessed installation situation but interfere less). Already at the "trial run", however it turned out that the seals used not really tight and water collects in the spotlight. Before final installation I have therefore cemented the glasses with silicone - now everything stays dry.
