Ruby luminaire is in the form of a caterpillar of a good 40cm long with a weight accordingly as the spheres forming the body are painted wood matt colors look great. The head is composed of a light bulb with a metal structure to slide over. The downside was indeed to find a strict equivalent to the original bulb under penalty of being unable to replace the metal structure forming the eyes and antennae. But that's a detail.
Also note: Do not worry about the advertised power of the bulb. It lights a lot, maybe too much if the child is still very young. This is actually equivalent to a 60W bulb if I remember correctly. In any case, your room will not be dark with this caterpillar.
Finally, a minor complaint can be made on the cache because it is much too small to hold excess cable as I has a height of 2m50 ceiling. I had to cut the cable to have a good parallel cache wireless ceiling full of one side or the other. Again nothing major but it will be certain to lose less time.
Finally, Ruby is a beautiful luminaire sold at excellent quality / price. I can only recommend it provided you have a hook supporting the considerable weight of this very pretty caterpillar.
