Although I found the design with the spiral a bit strange - they were to Glücjk anyway - it makes a very pleasant light. In a short time - less than 2 minutes - this Eneriesparlampe has reached its full capacity. But acuh the initial power is indeed thieves, but sufficient. For me, this lamp is currently an almost 30 sqm living room lights out. The light is hardly reduced by the actual lamp. The other energy-saving lamps, which I had already tried, have managed it not so good. Also the price is less than EUR 10.00 pretty good. With 12 watts of power consumption and light output She's really good.
Update - 27.01.2012 Meanwhile, I have the energy saving light bulb for more than 12 months in use. Still super power. I guess she was now used more than 500 hours! So it must be with a good quality product.
