I was so looking forward to the LED lamp, so that I can replace my halogen bulb desk lamp against these LED lighting. At first I had ever made to the article wait (after 4 weeks I have not counted on) and then I had the brackets in the desk lamp to bend so that the LED purely fit. After that was done, I could fix just about the lampshade (curved glass) through small renovations. .... Light super bright ... but then the hum of the lamp at the desk ... you'll crazy ... after a few minutes "so-so-fun" began the lamp will flash and the lights went out and an .. . Before then what is broken I have the lamp expanded nand plugged my Halogener .... Too bad .... again 100 watts instead of 10 watts ??? ??? But decent light - no hum and flash ... shame !!!!!!!!!!!
