Light at the start of the day is the most effective way to reset your internal clock and the daily cycle of hormones, metabolism and sleep. The Bodyclock Spark 100 from Lumie is a Class 1 graded medical device that will introduce you to the benefits of sleeping and waking with light, so that you can experience a more regular sleep and wake pattern.

Wake up bright
Bodyclock Spark 100 gently starts to brighten 30 minutes before your alarm time, waking you naturally as it reaches full brightness. Set you preferred final light intensity and wake up to a warm glow or a bright, sunny room. An alarm and tap-control snooze add reassurance. Waking up with gradual light has been proven to boost mood, productivity and energy levels, so that you feel brighter and ready for the day ahead.

Unwind and drift off naturally
Wind down gradually with the sunset feature that lasts 30 minutes. Fading light is a signal for the body to produce melatonin ready for sleep, so the sunset makes you naturally drowsy. Realistic lighting fades through pink, orange, red then turns off or stays at a soft glow if you set the nightlight feature.
