Tunable White Smart Bulb FAQs
What is the difference between Tunable White and standard LED bulbs?
Tunable White bulbs allow you to adjust the color temperature (CCT) from warm amber (2700K) to cool daylight (6500K) via an app. Standard LEDs have a fixed color that cannot be changed.
Can Tunable White bulbs help improve sleep quality?
Yes. By automating the shift from cool daylight in the morning to warm amber light in the evening, you support your body’s natural circadian rhythm and healthy melatonin production.
What Kelvin setting should I use for reading and focus?
For tasks requiring high focus, use a setting between 4000K (Natural White) and 5000K (Daylight). This crisp light reduces eye strain and promotes alertness during work or study.
Can I use smart tunable white bulbs with a wall dimmer?
No. Smart bulbs should be used in non-dimmable fixtures. Dimming is controlled exclusively via the Feit Electric app or voice assistants to prevent flickering and hardware damage.
How do I automate my smart bulbs to change color with the sun?
Using the Feit Electric app, you can enable 'Circadian Rhythm' schedules. These automations automatically adjust your lights' warmth and brightness based on your local sunrise and sunset.
