While Vitae can fit any light fixture with an ordinary E27 Edison screw, it is most suited for more localised eye-level light sources like desk and nightstand lamps or floor lamps. If this is not an option, we feel Vitae’s bright white phase performs the best in ceiling light, however, the orange phase in a ceiling light also is suitable for bathrooms during the evening and night.

We recommend Vitae for desk, bedside and nightstand lamps in bedrooms and kids’ rooms as well as sofa reading lights and night-time lights in the bathroom and the toilet. In the evening it is advisable to use lights that shine below eye-level, just like the firelight does.

This varies greatly for each individual as it heavily depends on how much your circadian rhythm is desynchronised. Normally positive results can be observed after one week’s use. It is very important to note that 90 minutes before sleep to be precise, 9 and a half hours before waking up in the morning, no blue or green wavelengths should be hitting your retina (i.e. specifically wavelengths below the 550 nm threshold). Vitae’s orange phase will not have a beneficial effect for your sleep and melatonin secretion at night if other full-spectrum lights that emit blue or green wavelengths are used concurrently such as:

• full-spectrum white or warm-white LED lights
• RGB LED lights that that mix blue and red to create light we perceive as orange
• undimmed incandescent light bulbs
• fluorescent light bulbs
• computer screens and mobile phones without red screen enabled (Apple’s Night Shift is unfortunately not sufficient as it still allows for blue light emission – see how to turn the red filter on your iPhone)
• TV screens

For instance, if you use Vitae 90 minutes before sleep in your bedroom only, the full-spectrum white or warm-white light in your other rooms in the evening and during the night will still keep on inhibiting your melatonin secretion. The same happens if you watch TV or use your smartphone or computer without a red filter prior to sleep. As a result, you will not benefit from Vitae’s orange phase, which is devoid of blue and green wavelengths below the 550 nm threshold. In cases when you can’t avoid such blue-rich lights (e.g. when travelling or for an urgent work email before sleep), use blue-blocking red glasses.

Yes, it is – Vitae is optimised for desk, bedside and nightstand lamps in bedrooms and kids’ rooms as well as sofa reading lights and night-time lights in the bathroom and the toilet.

We believe in simplicity. App-controlled lights are always in the stand-by mode a never properly turned off, thus emitting electromagnetic radiation and using energy at all times. Also, such remote control requires the use of a phone which without a red screen inhibits melatonin secretion at night. Vitae is simply controlled manually with your light’s switch. When turned off, it truly is off and does not emit any light.

90 minutes before sleep (to be precise, 9 and a half hours before waking up in the morning), no blue or green wavelengths should be hitting your retina (i.e. specifically wavelengths below the 550 nm threshold). Our eyes have been evolving for millions of years under the influence of the sunlight – as a result, our circadian rhythm, our inner biologic clock, is synchronised through it. Sunlight emits all visible wavelengths (i.e. colours) during the day, but as evening and sunset approach, the short blue and green wavelengths are filtered out thanks to the Earth’s atmosphere. Therefore, the light at sunset appears warm and red. The missing blue and green wavelengths are a signal to our body that the night is approaching and melatonin secretion should begin. Melatonin will be secreted into our blood after roughly 90 minutes since the last moment blue or green wavelengths hit our retinas. Consequently, it is very important not to hinder or delay this secretion in the evening or during the night. Melatonin is a very important hormone that plays a crucial role in sleep, metabolism and works an antioxidant against varied diseases such as cardiovascular diseases and cancer.

Unfortunately, there will be no such model as Vitae’s heat exchange surface does not allow for this. Vitae needs perfect cooling – with an E14 screw, the chip inside would overheat quickly.

To test if your lights are flicker-free you just need a smartphone. Approach a light you would like to test and view it through the phone’s camera – if you spot vertical lines running through the light, it is very likely such light causes flicker and eye strain. The second option is to shoot a video of the light with the slow mode turned on.

Apps like F.lux often only limit blue and green wavelengths emitted by screens, but they don’t eradicate them completely. Consequently, 90 minutes before sleep (precisely nine and a half hours before waking up in the morning), we recommend you wear our red glasses in case you need to work late on your phone or computer (of course, using electronic devices before sleep should not be the norm). It is not necessary to wear red glasses if the free native red screen colour filter is used on your Apple devices or if you use the Iris app:

• For how to set a red screen colour filter on your Apple devices see instruction videos on our YouTube channel. Links: red screen filter how-to for iPhone/iPad and for MacBook/iMac.
• Iris app is a cross-platform app that can fully eliminate blue and green wavelengths. Available for desktop computers, tablets and smartphones –  Android, Mac, Windows and Linux systems are supported.
