EV SUN fixtures do two jobs at once. They light a room the way good lighting should — and for as long as they are lit, copper-ion resonance technology works on the air and surfaces around them.
Copper-ion resonance technology is built into the luminaire itself. There is no separate unit to install, no cartridge to replace and no consumable to reorder.
The effect runs whenever the fixture is lit — it needs no switch, timer or user action of its own. Because lights are typically on for much of the day, protection accumulates over those same hours.
Unlike UV-C systems, EV SUN emits no ultraviolet light. Rooms stay in use while it works, which is why it suits homes, clinics and classrooms.
Independent testing measured how bacterial counts fall under continuous EV SUN light — first under controlled laboratory conditions, then in occupied clinical and education environments.
Beyond the laboratory, airborne bacterial and fungal counts were measured before and after installation in occupied real-world environments.
A specialist outpatient centre in Singapore, sampled across a full 24-hour cycle.
An occupied hospital ICU, monitored across staged exposure intervals.
An active children's room, sampled before and during operation.
Resonance frequency technology runs through the whole catalogue — from recessed downlights and utility fittings to the Lumora and Aura decorative ranges.
Complete third-party test documentation — methods, organisms, exposure conditions and results — is available to architects, consultants and procurement teams on request.
Figures shown are drawn from independent third-party test reports commissioned for EV SUN lighting. Results reflect the specific samples, distances and exposure durations tested. Performance in any given space will vary with room size, air movement, cleaning regime, humidity and fixture placement. EV SUN lighting supports environmental hygiene alongside normal cleaning practice; it is not a medical device and is not a substitute for cleaning, ventilation or infection-control procedures.
