Lumie Bodyclock Spark 100 SAD Wake-up Light Alarm- FAQs
Does the Lumie Bodyclock help with SAD?
Yes. The gradual sunrise simulation helps regulate your circadian rhythm, making dark mornings easier and providing support for winter blues and Seasonal Affective Disorder (SAD).
Does the Lumie Bodyclock actually wake you up?
Yes. It slowly brightens over 30 minutes to mimic a natural sunrise, helping you wake gently and feel more refreshed.
What exactly is the Lumie Bodyclock Spark 100?
The Spark 100 is a wake-up light with a 30-minute sunrise and sunset simulation, adjustable brightness, and auto-dimming display for a natural sleep–wake routine.
How is the Spark 100 different from other Lumie sunrise alarms?
The Spark 100 uses warm white, orange, and red LEDs to mimic sunrise/sunset colors. Other models (like the Sunrise Alarm) add nature sounds and more brightness/customization options.
Is a Lumie Bodyclock worth buying?
Yes. Users report better sleep quality, easier waking, and a more relaxing bedtime routine thanks to the natural light transitions.
Does the Spark 100 have sound alarms?
Yes. It includes a simple audible alarm alongside the sunrise light for reliable waking.
Can using my phone replace a Lumie wake-up light?
Not effectively. Phone screens emit blue light that disrupts sleep, especially when used before bed. Lumie lights avoid this and follow natural light cues.
Are Lumie products safe to use?
Yes. Lumie devices meet safety standards. Very old units may have had adapter issues, but current models use safe, updated components.
How long should I use a SAD light each day?
Most people benefit from 30–60 minutes daily. Longer sessions are also safe if comfortable.
Are there any side effects of bright-light therapy?
Some sensitive users may feel mild eye strain or headaches. If this happens, sit farther away or take breaks.

you’ll wake with a gradual sunrise and any other sunrise options you have set. See also Alarm time and sunrise options, page 5.
