Osram LED Star PAR16 7W 50 (replaces 50W) GU10, extra warm tone (827), reflector shape 50 mm, 230 V, 36 Beam 910355Habe me buy these bulbs from advertising. Had in my living room 200W (50W x 4) halogen spotlight inside. In these current prices I dared not, this to turn longer. In the transitional period, these replaced even partially my radiator. Now finally have the 50W halos reasonable substitute by LEDs and now that they are especially affordable, I replaced them October 2013. Old out, new unwrapped, used, fit 1A pure. But if a few grams heavier, but never mind. In the evening when it finally got dark, I turned it on. All lit up in a pleasant warm white. The is only minimally different from the Halos - are an alternative. Negative lot to me that the viewing angle is really like spots. Well, realigned lamps, but I can live with that the ceiling is no longer fully illuminated, but the selected corners in the room. But for pretty much 65 minutes began a lamp flashing. This should not stop too. Then went to sleep. The next morning I turned on the lamp and let it burn. After again the same time (about 1 hour) the same problem, the same bulb was blinking. I switched off the lamp, waited a few minutes, and then unscrew the broken. And I realized that it was hot, the other 3 lights only lukewarm. Have exchanged the same day without these problems to the dealer, used the new and turned the evening and waited. All lights, as it should be. Now everything seems to be ok. With the lights, so the manufacturer saves (7 W to 50 W) to get a whole lot of power, without feeling guilty. Just hope that the service life is also as indicated. If what give new, so I will post it here.
