Square One Halo

A square internal decorative luminaire with a halo backlight.

Improving upon the Square One, we introduced the Square One Halo to the interior lighting range. Featuring the same contemporary design, shatterproof polycarbonate shell, and cambered sides, but now flaunts a decorative halo effect backlight in a range of colours.

The Square One Halo meets demands for a flexible, attractive, energy saving luminaire, with a choice of finishes complementing a wealth of installations.

The Square One Halo provides not only the latest in lighting design technology, it cleverly combines design and practicality; the cambered profile is provided in tough shatterproof polycarbonate which is tough hard-wearing and vandal resistant.

Features

  • Wall or ceiling mounting.
  • Integral 3 hour maintained emergency option (HF).
  • Self test emergency option.
  • Tough polycarbonate body and diffuser.
  • Wire drop down pendant.
  • LED options available.
  • eMotion™ corridor function.
