First great joy over the bright light (600 lumens), which perfectly corresponds to a 50 to 60 watt bulb. Also nice that while only 8 watts consumed. The manufacturer promises a lifespan of 50 000 hours. Unfortunately, the lamp was broken after an hour. She was free-standing screwed, so that no heat accumulation could occur. Due to the short burn time I can not therefore recommend! The quality assurance by the manufacturer, apparently leaves much to be desired.
