Why I give 5 stars for this LED light: Super light, very pleasant light color, light can be rotated in different positions, thereby the viewing angle, no humming and no bing-bing-bing more changes until they are concerned, price / performance, Verpackung.Meine came easily to lediert, the lights were still healing. What I do not like: Bundled with the light guide confused more than it benefits. Here's my suggestion for those who are a bit Technically gifted, as the lamps are installed on Lightest: The people completely disconnect. Most have the caps at the end of the fluorescent tube, it is enough one on each side, which does not matter thin cable. On the other hand the gleiche.Auf the side on which the warning label is attached, the neutral conductor (blue wire), on the other hand, the conductor (black cable) is reconnecting. Remove the starter and purchase as no blind starter now. With terminals (Wago or screw terminals) and two short cables to connect to the stream, once the left and right, installation ready. The end pieces of the new lights are twisted slightly, align, hold at the end pieces between thumb and forefinger and screw. READY
