This was a replacement for my trusty original Lumie light bought several years ago. The actual light itself is excellent BUT the controls are frustratingly complicated and fiddly. Not at all intuitive and certainly requires you to get down on your knees to view the minute display items. There isn't a one button override to switch the radio on if you happen to wake up with the light before the set time. Worst of all the display light is far too bright even at minimum setting it bathes the room in a faint blue light (which I believe is the one wavelength that the eye can pick up at low intensity. So have to have it off completely so I am getting used to not knowing what time I got out of bed for my night time wee!
