Key Features

Haloprism fuses the latest in LED technology with the distinguished dynamics of Holophane's durable prismatic glass optics. Combined to deliver the highest LED lumen package, longest system life and lowest maintenance high bay luminaire solution.

  • Finned luminaire design with inner and outer perimeter chamber vents, utalises conduction and convection to ensure heat is managed away from the LEDs to maintain a long system life. 
  • Ventilated driver chamber optimises cooling by natural convection of air over heat sensitive electronic components and ensures dust build-up is minimised.
  • Incorporates PrismaLED technology which delivers a wholly luminous effect that accurately controls the output of the LEDs and reduces glare. 
  • Glass refractor technology with rounded ‘light blending’ prisms on the inner surface and sharper ‘light controlling’ prisms on the outer surface help to ‘blend and shape’ the light output. 
  • Five distributions catering for a wide range of high mounting height and spacing requirements.
  • Low electrostatic ‘semi-torus’ glass optics and the vertical ventilation slots of the luminaire heat-sink work together to create a self-cleaning optical system. 
  • Glass optics proven to minimise dust and dirt accumulation over time, dramatically improve the lumen maintenance over life.
  • High quality, efficient LEDs used in conjunction with the latest in LED drivers ensures that the best lumen per watts and a long system life are achieved.
  • DALI (up to 3 x DALI addresses) and 1-10V analogue controls options available. 
  • Fully integrable into Holophane’s HOLOS system. 
  • Local control via standalone 1-10V infrared presence detector (HEL.PIR) - accessory. 
  • Plug and play controls connection.

The luminaire shall utilise PrismaLED optics consisting of twin-active, prismatic glass lenses manufactured from soda-lime glass (SiO274Ca011Na2O13) mounted with specially designed stainless steel deformable clips to hold the prismatic glass in place. The fully ventilated finned luminaire chassis is manufactured from LM20 aluminium (AlSi12Cu) to maximise heat transfer.

The luminaire, with inner & outer perimeter vents and ventilated electronic driver chamber, utilises all three heat transfer mechanisms of conduction, convection and radiation to ensure that the LEDs mounted to the aluminium backed PCB and electronic drivers are thermally managed.

The prismatic glass lenses are sealed within the main luminaire chassis with a die cut gasket that has internal wire pass holes to ensure IP65 is maintained.

Lighting Design

Holophane offer a comprehensive and professional lighting design service. Our experienced and qualified lighting designers are on hand to provide full project support ranging from simple calculation plots to full complex lighting designs.


Product Matching

Holophane’s history lies in it being the first company to give practical application to the principles of the prism as the ultimate means of light control, harnessing and redirecting the output of light source by prismatic means to provide the best in cost effective, efficient lighting.


More light, less Investment

We believe that our products are better, more cost-effective and longer-lasting. And we'd like you to put that to the test.
