I have been four of these lamps in use. For quite some time light up three in transition and since today also in the bedside lamp in the nursery. The color rendering of the lamps is very pleasant and the brightness is the power guzzlers in every way! The light color "warm white" really deserves this lamp from Philips! The specified switching frequency of 50,000 on / off switching operations is also quite high. If I do that with the LG E27 LED comparisons that are comparable in terms of color reproduction and brightness, there are indicated only 15,000. The dimming I have not tested. I know, however, from my optician who also used these lamps that this will work properly.
Those looking for disadvantages, which it naturally finds. The beam directly below the lamp is of course not as great as with the conventional. Due to very high gear, where the lamps are used, but this is of no consequence. As a reading light in the bedside lamp the light color is also very pleasant
I highly recommend these bulbs. Despite the higher purchase price, it is preferable "noname" lamps definitely. I use LED lights for many, many years and have previously always bought cheap. But one learns that Philips are worth the money ...
Whether or LED bulbs, I buy everything now from Philips and am very satisfied!
