Light as Nature Intended

Meet Vitae, The All Day Bulb


At noon, the sun's rays have the shortest path through the atmosphere, providing a blue-rich light that sharpens focus.


As the sun nears the horizon, its rays have to travel a longer path through the atmosphere, filtering more blue light, making the light warmer.


After nightfall, the absence of blue light signals the onset of rest time. Vitae lets you follow these natural light cues to enhance your life.

Blue Light Blocking


  • DEN covers places where you spend time the whole day, and is the most versatile.

Best option for new customers.

  • EEN concentrates more on spots where you won't work like living rooms.
  • ENN is best for bedrooms where you don't do much more other than prepare for sleep.

During a full moon, the typical lunar illuminance is around 0.05 to 0.1 lux, but under exceptional conditions like a supermoon, it can go up to 0.26 to 0.30 lux.

But even such a tiny input drives the monthly cycles of the whole natural world, like animal behavior, plant growth, human sleep and behavior.

For comparison your phone on minimum brightness still shines somewhere around 0.44 lux from about 20cm distance.

So your body likely experiences a supermoon on steroids every single day before you go to sleep.

Only recommended in small bathrooms (up to 5m²)

Vitae is made for localised task lamps. It should never shine right into your eye.. use of non translucent lamp shades is recommended.

However, with around 5 Vitae bulbs, you can get adequate lighting for a room ca 20m².

We believe in simplicity.

If app operated, vitae would no longer be night safe, since it would require you use your phone and thus possibly exposing you to blue light.

Benefits of the manual approach:

  • Decreases screen time
  • Easy use for small children and elderly people
  • No WiFi dependancy
  • Energy efficiency - no standby energy consumption
  • Reliability

Vitae won't save you from other light sources. The night safe mode was tailored to emit light invisible to the retinal ganglion cells which react to blue wavelengths and signal daytime. For optimal results, use Vitae's first mode 90min before sleep and as the only light source.

Rooted in Innovation

Our bulbs are born from dedicated research and development. Each bulb carries a legacy of ingenuity, delivering a unique lighting experience to honor your circadian rhythm.
