Construction Details The luminaire consists of a separate lamp, control gear and spigot compartment. The control gear housing is separated from the lamp housing for thermal reasons. It is designed to operate 250/400W mercury vapour and 150/250/400W high-pressure sodium/metal halide lamps.

SABS Marks The luminaire bears the SANS 475 mark and the SANS 605982-3 safety mark. Luminaire spigot entries comply with SANS 1088 - Table 1. Side entry - ø42mm x 125mm.

Ingress Protection The luminaire has a degree of protection that complies with SANS 60598-2-3. Lamp compartment: IP 66 Gear compartment: IP 66 The IP ratings are certified by SABS test reports.

Lamp Compartment The housing is robustly constructed, weatherproof, hail proof, corrosion proof and vandal resistant. It is manufactured from filled ultraviolet stabilized engineering polymer and is grey in colour. An exterior lip is provided on the lamp housing to avoid direct rain water contact with the gasket, thus ensuring that no moisture is sucked into the diffuser when the luminaire is switched off and cools down. The non-discolouring high-impact acrylic diffuser bowl has no external prisms and is held to the housing by three stainless steel clips. (Five in the 400W version.) It remains attached to the housing when hinged open. The gasket sealing the lamp compartment is made of silicon sponge rubber and is fitted into a tongue-and- groove arrangement. Reflectors are manufactured from 99.98% super pure deep anodized aluminium and are not subject to accidental misalignment. The lamp holder complies with VC 8011, is rated to withstand 240˚C/5kV and prevents possible loosening of the lamp caused by vibrations.

Gear Compartment The control gear compartment is manufactured from highpressure die-cast aluminium to ensure excellent heat dissipation and optimum strength. It is covered by a hinged, non-corrosive lid which fits into a silicon sponge gasket in the body, into a tongue- and-groove arrangement. The IP 66 ingress protection rating ensures that all control gear components are protected against the ingress of dust and moisture, thus preventing corrosion and premature failure. The control gear is mounted on a removable gear tray and is suitable for operation with the specified rating of the lamp on a 230V +3%/-10% 50Hz single phase system. All control gear components are removable. Ignitors, where applicable, are of the superposed pulse type. The luminaire is power factor corrected to a minimum of 0,9.

Spigot Compartment The separate spigot compartment houses the screw terminal block and wire clamp. No access to the control gear compartment is required for installation, thus possible damage to the control gear is avoided. An optional down facing miniature daylight switch can be fitted into this compartment, giving it protection against UV and ensuring extended service.
