Lumi already have a 200, we bought this 250 because we gave the 200 to our daughter. It is found that the 200 is better because of defects 250 more cheap finish (plastic instead of glass globe), too bright even lighting mode adaptation to luminosity, poor radio reception, ergonomics complicated (we struggled to find how to have white noise to sleep to the point that we almost return !!). We can not use the benefits of 250 compared to 200: radio (it only picks NOTHING) and time autimotique radio signal (puisq'on does not pick up radio ...). In short, the positive is recommended 200. Point 250: Rather design, but it's subjective ...
