The somewhat heavy LED bulb lights up in a pleasant, warm tone. The brightness corresponds to the previously used 60W light bulb. Like all been related to me by LEDs products CHANGE THE WORLD is serving very well. The size is similar to the conventional light bulb (st neck a little thicker) and can be virtually anywhere where previously E27 standard bulbs were inside, screw. On the downside, the lamp LED does not immediately respond when I turn, but a quarter to half a second need to start - but then with full luminosity! A good buy for the reasons long-life LED technology and significantly reduced power consumption pays off well.
