Sleep and Light
Light triggers a hormonal response in our bodies to prepare for sleep. Dimming, warm light leads to melatonin production in the hour before sleep.
Melatonin levels decline gradually over the life-span and may be related to lowered sleep efficacy, very often associated with age, as well as to deterioration of many circadian rhythms.
Adults above age 55 are not likely to buy smart lights that can change color and brightness to aid with sleep, yet have a greater need for it.
Stupid Smart Lamp
A bedside or end-table lamp that can automatically fade color and brightness into the evening. Allow manual control to maintain familiarity with mental models. No smart home integration or set-up process.
