Save energy, I wanted to replace my 6 pcs. 50W low-voltage halogen spotlights in the kitchen for a long time to LED bulbs. I have already tested a number of different LED lamps, but that was so far never satisfactory because most of the light impression and the illuminance was not comparable. Because of the good reviews I've 6Stk. Osram LED Star PAR16 50 7W bought and ceiling spots rebuilt. I am absolutely positively surprised both light distribution as well as the brightness impression of converted spots with these bulbs is basically the same as above for the 50W NV halogen bulbs. The only thing that is different from the impression her, the lack of brilliance is when you look at even the bulbs on the ceiling, but that's really just a little complaining on the highest level. In the working areas there are compared to previously no smears, the light is practically identical in the opinion of me and my wife and with a connected load of 42W compared to 300W before. Class! Therefore I an absolute buy recommendation and full 5 stars.
Addendum on 09/02/2014 Based on the positive results after remodeling the kitchen, I have another 12 pcs. Of these Osram LED Star PAR16 bought 50 7W to replace the other halogen spots in the living areas. In these areas, as in the kitchen, the result is very positive, very beautiful light and virtually no concessions to the previous 50W low-voltage halogen lamps. After installing one of these lamps began after a short time, however, to flicker and was shortly afterwards completely. I hope this is an isolated incident and not a problem that the other bulbs also show yet. The old lamp I will complain first, further bulbs should be affected, I would this grudge in the review again. Therefore, a correction of 5 to 4 stars.
