SafeLight Continuous Visible Light Disinfection


Transforming hygiene with continuous visible light disinfection

SafeLight reduces germs in hygiene-sensitive environments using continuous visible light disinfection.


Conventional disinfection technologies are episodic in nature, i.e. they can be used only once in a while. This is because they are either impractical to be applied continuously, e.g. chemical sanitizers or unsafe to be used around humans, e.g. UV light. Therefore, their effects are temporary and bacteria, which can double in as little as 20 minutes, return to their original levels almost immediately after cleaning.

SafeLight’s patented visible light technology can kill bacteria, fungi and viruseswhile being completely safe to humans. Hence, it can be used continuously to supplement episodic cleaning and keep germ levels constantly low. It can be used in hospitals to prevent hospital acquired infections, in the food supply chain to minimize food spoilage and in offices and airports to reduce the risk of infection. SafeLightis currently in the process ofcommencing pilot trialswith partners in the healthcare, real estate andhospitality sectors. In the future, it also plans to expand to public transport and F&B.
