The light source can not keep up with the other current LED bulbs. The color reproduction is so bad that the lamp is to use most of basements. The shade of white is much colder than specified when other lamps the same color temperature, it is anything but "warm white". The efficiency is probably not so great, a 9.5-watt LED a brand manufacturer was much much brighter in direct comparison. The lamp is very reminiscent of the beginnings of the LED light means Conclusion: absolutely no use for my Gechmack for living rooms
