The light source is indeed almost as bright as a normal 300W halogen bulb in my estimation, but only exactly 6 months, and held less than 500h. The 2000h average burn time I do not think so, especially since I'm not the only one with this experience (or the dispersion is extremely high). The Leuchtstab change is too costly to 2x a year to do this, so I'll look around me now prefer an alternative.
