How to choose the right light therapy lamp?

To choose the right light therapy lamp , it is essential to follow certain principles and in particular ensure that it has all the standards and certifications required for optimal reliability, efficiency and safety.

The word “light therapy” is governed by European directive 93/42 CEE on medical devices. A light therapy lamp is therefore considered, according to this directive, as an active therapeutic device intended to act on the internal biological clock of the person using it: it is therefore a class I device. It makes it possible to effectively combat winter blues, seasonal depression or any other kind of desynchronization of the biological clock (jet lag, night work, sleep disorders, etc.). A good light therapy lamp must therefore have certain standards and certifications:


The Medical Device CE standard ensures that the manufacturer's products meet all the necessary prerequisites to be able to enter the class of medical devices having a real effect on the body.

This CE Medical Device approval is awarded by an independent organization which reviews, tests and validates all the characteristics of the products submitted to it.


Be careful, it is very common to see many irregularities, especially on the internet! Despite controls by competent organizations in all European countries, there is still an offer on the internet of products calling themselves "light therapy lamps" without having authorization. These lamps without medical approval can sometimes prove to be very dangerous: UV emissions which are particularly harmful to the eye, flickering, insufficient power requiring you to position your face less than 10 cm from the lamp, etc. To choose your lamp carefully, trust the French leader in light therapy, Dayvia, or make sure that the CE mark is on the product and on the packaging.

Unfortunately the word “light therapy” is often misused, you can even find certain bulbs on the internet that illegally use the term “light therapy bulb”. You should know that this marketing appropriation is completely abusive to the extent that no international study has proven the slightest therapeutic benefit using this type of ampoule, the prices of which are often very high.
