I am very excited about the Philips LED lamp. That is the 4th version of LED bulbs that I now have in my house in use. The 6 watt LED lamps have a pleasant warm light flicker, and not hide, are somewhat lighter than its conventional predecessors and consume it only 15% of energy. The lamp emits the light uniformly in all directions and it can be heard even no operating noise. Although the LED lamp is anything but inexpensive here, so it pays for itself over a conventional light bulb with 40 watts after a good and happy 1.5 years with a duration of 2 hours per day. If now even the specified duration is reached, then this is a real energy policy. Strong buy recommendation.
