Specifications

LIGHT EMITTING DIODE (LED) AND HIGH INTENSITY DISCHARGE (HID) BULKHEAD LUMINAIRE DESIGNED FOR INDUSTRIAL, PERIMETER AND SECURITY LIGHTING APPLICATIONS WHERE HIGH LUMEN OUTPUT IS REQUIRED.

The luminaire shall consist of a high-pressure die-cast aluminium body with non- discolouring prismatic high-impact acrylic diffuser bowl and shall be designed to operate 42W LED, 80/125W mercury vapour and 70/100/150W high-pressure sodium/metal halide lamps.

The luminaire shall bear the SANS 60598-2-1 safety mark.

The luminaire shall have a degree of protection that complies with SANS 60598-2-1:

Lamp compartment: IP 66

The IP rating shall be certified by an SABS test report.

The LED luminaire shall be designed with high efficient LEDs, 4000K at a colour rendering index ˃70, and a minimum 50 000 hours lifetime (L70). It shall have an operating temperature (Ta) rating of -20°C to +40°C. It shall be designed to retrofit 70W and 100W high pressure sodium and mercury vapour installations.

The body shall be manufactured from high-pressure die-cast aluminium. It shall be 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 shall be 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 shall be available for architectural applications. The body can be semi-recessed or surface mounted. It shall be available for Zone 2, 21 and 22 applications.

The diffuser bowl shall be manufactured from non-discolouring injection moulded high- impact acrylic. The prisms shall be restricted to the inside of the bowl and shall be 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 shall be held to the body by four stainless steel M6 Allen head captive screws located outside the sealed lamp compartment.

A high-purity, single-piece, die-formed aluminium reflector shall be mounted on the reflector back plate. An internal eyelid shall be available as an option when the luminaire is mounted in a vertical position against buildings, providing effective perimeter lighting.

The control gear shall be mounted directly onto the body to provide optimum heat dissipation. It shall be suitable for operation with the specified rating of the lamp on a 230V +3%/-10% 50Hz single phase system. All internal wiring shall be Teflon® coated with protective sleeving to prevent damage by possible abrasion.
