w181 Linier

A linear spotlight

At first glance, the w181 Linier resembles a linear pendant lamp. However, a closer look at its geometrically strict body reveals that there’s more to it than meets the eye.

Precisely defined light

A series of 256 deep-recessed individual optical systems, packed ultra-tight, provides a crisp directed light.

Glare-free light

Separate anti-glare compartments guarantee a comfortable, glare-free light with a low UGR (unified glare rating).

Versatile, integrated dimming

For a smoother user experience, the w181 Linier is available with integrated dimming wheels at both ends; each can be turned independently to set the desired light level, allowing for optimal adaptability.

Precise engineering

A lot of effort has been put into the precision engineering of w181 Linier’s sleek black aluminium body. For example, w181 Linier is suspended at its Bessel points to create perfect balance and stability in relation to its long, slender proportions.
