I bought first 1 lamp for testing and was immediately impressed. The white light is actually nice and warm white (comes now not quite up to the light color of a conventional light bulb out, but it is pleasantly warm and never cold white or even bluish light) - the luminosity corresponds entirely to my feeling of a conventional light bulb with 50 to 60 watts - the dimming function (4 steps, not continuously) using the remote control is working properly (by the way for all other colors!)
Have now 8 more lamps purchased and installed in different rooms of the apartment (the nursery, bedroom, bathroom is more, living room and 3x in milk glass tubes over the dining table and 2x in Wall Spots couch / TV area). The white light is in all the rooms pleasantly light, the remote control extremely comfortable (eg in the bedroom, when lying in bed) and as we mostly "globes" (the lamp is located in the center of a complete sphere of transparent plastic mesh or wire mesh) use there is also a great design and atmosphere in colored light.
The colors are the way the evening and at night strong, and in no way too weak (the day of course not make much sense) and in addition to the fixed 15 colors (plus white) can be by remote control also choose automatic Switching Modes (especially the slow, smooth transition from one color the next is very stylish) - especially with the wall spots can be in the evening a fine ambience spells (although I must admit that the lamps are much too large for the spots and we have the milk glass funnel not even screwed because the lamp yet anyway several centimeters was jut about it - but you get used to it and one can also buy larger spots)
It is important that you look at when purchasing the lamps also considered equal, in which lights you want to use this. There is quite a difference whether you simply can hang down only with a cheap umbrella from the ceiling lamps, that you can add globes, used as spots etc. Especially pleasantly surprised I was in the use of 3 lamps in each 3 frosted glass tubes of the blanket hanging over our table - x3 white light naturally has a good lighting power (in the evening then also dimmable) and the colors look through the frosted glass extremely beautiful and stylish (the light radiates less from the environment, but the frosted glass is self-catchers).
Especially cool is also the possibility that you can use all the lights with a remote control - which is not only practical, but it is also, as in our living room (1x lamp in ball hanging from the ceiling, 2x wall spots and 3x milk glass tubes about the dining table) playfully combine: the lamps in the milk glass tubes I have currently for example, 3 different colors (cyan, magenta and yellow) are set, the wall spots allowed to run through continuously, and hanging from the ceiling single lamp is easy to Weißlichtein- and off if one's light needs. Each lamp on and off, change color, dim, select color changing programs individually: everything goes with a remote control! (Coverage also works well, but also depends on how much the lamp is installed or not)
The disadvantages of the product are certainly the comparatively high weight and volume (longer and wider than conventional bulbs) - because of the weight lamps therefore always really firmly mounted on the ceiling and think because of the dimensions necessarily advance that the lamp fits in into the light !! (Had to disassemble for example one of our globes umständlichst or remove the retaining ring from the lamp body by force, because the lamp is not purely fit in the ball opening).
Buy, experimenting and then reorder better first lamp 1. Also be careful that not accidentally the Version 1 is purchased (is slightly cheaper) or "used" the product as supplied wrong on the Market Place (happened to me with a lamp, but was Amazon promptly in the course of a telephone conversation on Saturday night! ! replaced free - super) - Version 1 has a cold, bluish white light, the colors are not as nice and the dimming via remote control does not work either.
If the lamps last at least a couple of years (assume that the electronics adopted well before the predicted life of the LEDs themselves) they are the NGC. classic light bulbs high price more than worth it.
Thus a very strong buy recommendation on my part!
