I have already tested many LEDs. This is with regard to good color rendering, balanced color spectrum and illumination by far the best I've seen so far. Meets almost 50W, but compared to halogen has a slightly higher color temperature and no Rückleuchtung / side scatter. For the living room, bedroom and bathroom I sit on mixed operation for the useful range (gear, laundry, cellar, etc.) (LED alone would be too "cold"), absolutely ok.
