Have installed in August as a replacement for a defective 60W halogen spotlights in the carport this 10W LED spotlight. The 100W I can not confirm. Compared to the remaining 60W halogen spotlight this has a white light probably is not as bright in some. Quality makes the bottom line a good impression. The assembly less: a 4 screw holding the cover is attached behind was screwed awry and the screwdriver has inter leave a deep score in painted aluminum lid. I do not mind. The lid is clean & on the seal as well. Therefore 1 point deduction. Let's see how long it lasts
