CONSTRUCTION DETAILS The luminaire consists of a high-pressure die-cast

aluminium body with non-discolouring prismatic high-

impact acrylic diffuser and is designed to operate LEDs

of 42W,80/125W mercury vapour and 70/100/150W high-

pressure sodium/metal halide lamps.

SABS MARKS The luminaire bears the SANS 60598-2-1 safety mark.

INGRESS PROTECTION The luminaire has a degree of protection that complies

with SANS 60598-2-1:

Lamp compartment: IP 66

The IP rating is certified by an SABS test report.

BODY The body is manufactured from high-pressure die-cast

aluminium.

It is supplied with three mounting holes, but can also

be supplied with no holes in the body, using mounting

lugs instead, on request.

Electrical cable entry is via a compression type gland at

the rear of the luminaire, but other entries can be

provided on request.

A high-pressure die-cast aluminium decorative skirt

assembly is available for architectural applications.

The body can be semi-recessed or surface mounted.

DIFFUSER The diffuser is manufactured from non-discolouring

injection moulded high-impact acrylic.

The prisms are restricted to the inside of the diffuser

and are carefully formed to work in conjunction with

the reflector to provide a spacing to mounting height

ratio of up to 8:1, whilst controlling excessive glare.

The frame assembly is held to the body by four

stainless steel M6 Allen head captive screws located

outside the sealed lamp compartment.

REFLECTOR SYSTEM A high-purity, single-piece, die-formed aluminium

reflector is mounted on the reflector back plate.

An internal eyelid is available as an option when the

luminaire is mounted in a vertical position against

buildings, providing effective perimeter lighting.
