The Lumie Bodyclock Active 250 rouses you with a simulated sunrise. Light sleepers might find themselves jolted awake, as the light increases in steps rather than fading up gradually, but those who snooze more heavily are likely to find the experience more effective. Optional nature sounds can stop you oversleeping, though the short looping samples aren’t very relaxing. The sunset mode works well though, and encourages you to settle down at night rather than spending time checking Twitter on your phone. There are more sophisticated wake-up lights, but the Bodyclock Active 250 is well worth considering if you sleep heavily, particularly if you can find a good deal on it.
The Lumie Bodyclock Active 250 is a wake-up light and alarm clock that aims to rouse you gently with a simulated sunrise that increases in brightness over a period of time, with pre-programmed nature sounds to ease you into wakefulness. How well it works will depend on how heavily you sleep.
Heavy sleepers will be able to snooze through the earliest stages of the sunrise and be woken gently as the brightness increases, but the illumination increases in steps rather than gently fading up, so those who sleep more lightly may find themselves startled awake by it. Similarly, the sounds (including a running river and birdsong) are very short, and loop after just a few seconds, which can become irritating rather than relaxing.
