Circalux Night-Light Survey
Hello! We are working hard to create a smart night-light product that is circadian friendly and user-responsive.

What is circadian-friendly: a light that is still white, but minimizes blue in its color spectrum. Blue light has the biggest effect on depressing melatonin level at night. Melatonin is a hormone, naturally elevated in our body in the dark/during sleep. It guides our sleep-wake rhythm, and many other biological processes!

Having developed the light using proven scientific principles, we hope to bring healthy illumination for night-time tasks.

The idea was born out of the need to have a better, more patient-friendly night-time illumination for caregivers in hospital rooms (notorious for poor sleep and vulnerable to light disruption). However, we think it would be just as useful for people who need to wake often during the night (parents of young infants, frequent bathroom trips, etc.) and would like light to automatically brighten their path.

Your answer
Are you the overnight caregiver for someone? *
Do you use night-lights in your home/apartment? *
If you use night-lights at home, in which rooms do you use them?
If you have children, what are their age ranges? *
How often do you get out of bed at night (for any reason)? *
Do you turn on the overhead lights when you check on your child or walk around the house at night?
Would you be interested in affordable circadian-friendly lighting options for your home? *
How important/essential would this feature be to you: Accurate distance activation, where at 8 feet away (room's length) the light illuminates and brightens as you get closer, but you would need to wear a fob/transmitter. *
Would prefer an on/off/intensity knob
Absolutely, handsfree is a priority
Alternative to wearing a fob/transmitter: having a bluetooth phone app that can trigger the lights based on distance, but sacrificing some performance accuracy.
Wouldn't sacrifice accurate performance
Greatly preferred
How important/essential would this feature be to you: If the light turned with loud sounds, such as your morning alarm going off. *
not at all important
Would add great value to product experience
How much would you spend for a circadian-friendly lighting device? *
Would you buy a Circalight, as described on
