We have replaced our 25 W halogen spotlight with these LED lights. The room is now illuminated much brighter than before, hence the statement is true "(replaces 35W)" well. Advantage of Osram LED Star compared to many other LED lamps is that they have approximately the same viewing angle (about 36 °) as halogen spotlights. The base fit well in our lampholders, even if the lights a trace "higher" are.
The housing will be in continuous operation lukewarm, the light color is slightly "warmer" than halogen and very pleasant.
