Scientific research shows that the light that we are exposed to every day is the main influencing factor on our mood, energy levels and sleep. Getting the right light at the right time is imperative for good health and wellbeing. Healthy light is a combination of the right intensity, spectrum (colour), timing and duration of light.

The installation process of your bulbs is really easy and will be detailed during your first connection to the app. All you have to do is to plug in our smart bulb as every normal one and to follow the instructions on the App.

When you purchase one or more bulbs, you also get access to our app. After a simple pairing process, all your bulbs will be connected to your account on the App. After a short questionnaire, our app determines the right light for you and automatically controls your bulbs to emit it.

If for some reason you want to manually change the settings of your bulbs (colour or intensity), you can do so directly from the App.

The different types of bulbs you can find on our website differ by their fixture (i.e., the connection between the bulb and the support). 

Here is a small guide to help you choose the right type of bulb.

E27: is the most widely used in Europe and the classic representation of a bulb. This bulb has a cylindrical fixture with a 27mm diameter and has to be screwed in at the support. You can typically find it in a range of domestic settings for lamps and feature lights.

E14: is the new general screw-in design and is the same as B27. However the fixture is a bit smaller with a diameter of 14mm. It is widely used on compact lighting systems (like a desk lamp).

B22: is almost only used in the UK. It is very similar to the E27 but differs a bit in the fixture. Here you can find two pins on the side of the bottom part of  the bulb that allow it to attach to the fixture.

GU10:  is most of the time used in the ceiling of your kitchen and in your bathroom. It is shorter than the other bulbs and has two pins on bottom.

Visible light comprises a number of different colours. The spectrum of colours in visible light can be seen in rainbows and is typically divided into red, orange, yellow, green, blue, indigo, violet.

When we talk about blue light, we are simply referring to the part of light that makes up the blue part of the spectrum. Blue light is special because our eyes have evolved to use blue light to send a message to our brain to communicate if it is daytime or nighttime.

Prior to the invention of electric lighting, the rising and setting of the sun would be the only way our brains would know the time of day which is important information for our body's master clock - our circadian rhythm. Blue light during the morning is a good way to wake up naturally while blue light at night is generally bad because it disrupts this natural cycle that evolution developed for us.

The existence of blue light in electric lights and computer screens means that we have to take steps to avoid it and why LYS is working hard to bring healthy lighting back into the home and workplace.

For now our bulbs are available in the European Union  and in the UK. 

The delivery fees are £5. It will be clearly stated just after your checkout for payment. If you buy 5 bulbs or more, we take care of the delivery cost.
