Performance through Technology - Taking high bay lighting to new levels of lumen output with superior light control. 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.

For over 120 years Holophane has enjoyed an enviable reputation throughout the world for expertise, quality and innovation in Lighting. Form the earliest days, when the company pioneered its famous glass refractor, the Holophane name has been ever present as a leader in the field of luminaire and lighting design. Haloprism™ is a continuation of this proud tradition.

The luminaire shall utilise PrismaLED optics consisting of three, 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.
