This color change LED incl. IR remote control is the hammer! In larger local 'electric markets' with the signal colors red, blue and blue / yellow in vain wanted something similar. "Have we not. But we have this great" Wireless "-Farbwechsel Light" (a Dutch manufacturer that only about ten times as expensive ...). Well; thanks for nothing (again). Ergo researched briefly on Amazon and this lamps found. Stronger (but well dimmable!) Than expected sits the "Bulb" on a massive heat sink, which these do not really need, because at max. 10W this light is maximized at body temperature; and then only at the base, by the way - has been fitted in all versions - unlike some other light sources that I own. Brief Summary: Anyone who wants can use the lamp as a warm-white LED; who wants to take advantage of all the features, gets a small but fine - and bright - color show in saturated RGB colors, or delivered depending on their mixing all sorts shades. In "fade" - and "Smooth" mode the light between all possible shades WITHOUT changes aprupte color change; then there's still the "Flash" mode with high contrast and color changes ticked and the strobe mode, which is the name does not do justice as the only function; because an on / off per second is no stroboscopic effect. But when ordering I did not know that this function is also programmed. Who wants a strobe light, which must be separately ordered one or use an old tube monitor it. Otherwise: strong buy recommendation.
