Ring Blade™

RING BLADE reimagines the iconic circle, presenting a luminaire that’s as razor-sharp in design as it is revolutionary. By slimming the traditional profile to an ultra-modern 3/4” while amplifying light output, it stands as a paragon of contemporary precision. Its crisp form embodies unity and precision, exuding a distinguished presence. This luminaire delivers powerful, even lighting without glare, tailored for both ambiance and task. The ceiling mount options create the illusion of being recessed, offering a seamless integration with the ceiling, as though they are a natural extension of the architecture itself. Whether standing solo or grouped in audacious arrays, RING BLADE transforms spaces with bold luminosity and dynamic form, redefining the circle’s role in the lexicon of modern design.
