Description

The Glistenis is a 30mm diameter glass lens that narrows the beam angle of compatible downlight fittings to 20, creating a tightly focused spot of light. The lens sits in the downlight aperture and uses optical refraction to concentrate the light output into a narrower cone than the fitting’s standard beam angle, which typically ranges between 40 and 60 depending on the fixture.

Designed for accent lighting, the 20 beam angle suits applications where concentrated light is needed on a specific object or surface: artwork in galleries, retail display shelving, architectural details, feature walls, or worktop task zones in kitchens. The narrower beam reduces spill light into surrounding areas, creating higher contrast between lit and unlit zones and giving more control over where light falls in a room.

The 30mm diameter fits the majority of recessed downlight housings that accept interchangeable lenses or reflectors. The gl
