The Vortex 31 Series is a compact LED downlight with an 80mm bezel and 70 mm cut-out, designed for architectural applications where low-glare, high-quality lighting is essential.
It features a 36° faceted reflector, a die-cast bezel, and an injection-molded low-glare baffle. This luminaire has a lifespan of over 50,000 hours and includes options for dimming, DALI, emergency modes, and Bluetooth Casambi wireless control. Available in 3000 K or 4000 K colour temperatures, it is flicker-free in compliance with IEE PAR1789.
The Vortex 31 Series is an integral LED downlight engineered for seamless ceiling integration in commercial and retrofit applications.
Combining a low-glare 36° faceted reflector with IEEE PART 789 2015 flicker-free compliance, this professional-grade luminaire delivers reliable illumination for offices, retail spaces, and hospitality venues. Backed by a 5-year warranty and >50,000-hour lifespan, it offers a cost-effective LED downlight replacement solution.
