I've gained the mentioned GU10 60LED bulbs as part of a realignment of the home lighting in our house. The lamps are used as a replacement to 35W halogen high-voltage reflectors. Ever since the first time I've seen the lamps, I am thrilled. A brightness that rivals the 35W high-voltage bulbs in nothing. On the contrary, a bright and clear light (lighter than the halogen lamps, but still to be defined as Warm White and pleasant for the living room). The power savings is, of course (as in the usual LED technology) tremendously. If you have these bulbs once experienced "live" can only conclude that the LED technology is finally mature and suitable for everyday use. The price is unbeatable in my opinion. I even compared the so-called "no-name products" in the construction markets locally with this product and which are partly more expensive by 2 to 2.5 times. I'll replace the bulbs now wherever it is possible. I can only say: Those looking for a replacement for halogen lamps, which is no way around this product. From me there is an absolute buy recommendation.
