I've Never Used a Philips Hulits Watch for Sleep Tracking

Sleep cycle uses lights to wake you up from a deep sleep. The alarm on the watch doesn't make any noise, so it can be used without waking your spouse. But i've found that not because it's linked to a specific light bulb. If she's getting up a little bit earlier, it doesn't realli bother me. Or if i'm getting up alte bit earlier,it doesn't really bother her. Anyways, not really a big deal.
