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 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.
A borosilicate glass diffuser with internal prisms is available as an option.
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.
Electrical Components
The control gear is mounted directly onto the body to provide optimum heat dissipation.
It is suitable for operation with the specified rating of the lamp on a 230V +3%/-10% 50Hz single phase system.
All internal wiring is Teflon® coated with protective sleeving to prevent damage by possible abrasion.
All external screws, bolts and metal parts are stainless steel or non-corrosive material.
Ignitors, where applicable, are of the superposed pulse type.
The luminaire is power factor corrected to a minimum of 0,9.
