Construction Details The luminaire consists of a lamp compartment separated for thermal reasons from the control gear compartment and is designed to operate up to 100W high-pressure sodium (BEKALUX), or up to 400W high-pressure sodium lamps (BEKASUN).

SABS Marks The luminaire bears the SANS 475 performance mark and the SANS 60598-2-3 safety mark. Luminaire spigot entries comply with SANS 1088 - Table 1. Side entry - ø42mm x 125mm long

Ingress Protection The luminaire has a degree of protection that complies with SANS 60598-2-3: Lamp compartment: IP 65 Control gear compartment: IP 43 (BEKALUX) IP 23 (BEKASUN)

Lamp Compartment The housing is robustly constructed, weatherproof, hailproof, corrosion proof and vandal resistant. It is manufactured from filled ultra-violet stabilised engineering polymer and is grey in colour. The high-impact, non-discolouring acrylic diffuser bowl has no external prisms and is held to the housing by three stainless steel clips. 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 anodised aluminium and are not subject to accidental misalignment. The lampholder complies with VC 8011, is rated to withstand 240˚C/5kV and prevents possible loosening of the lamp caused by vibrations.

Control Gear Compartment It is covered by a hinged, non-corrosive lid which allows access to the control gear and spigot mounting. Access to the gear compartment is gained from underneath by loosening one captive stainless steel screw. The gear compartment is manufactured from high- pressure die-cast aluminium to ensure excellent heat dissipation and optimum strength (BEKASUN only). 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 and bear the relevant SABS mark. All internal wiring is Teflon® coated with protective sleeving to prevent damage by possible abrasion. All screws, bolts and metal parts are stainless steel or non-corrosive material. Mains connections are by means of a suitable screw terminal block with a wire clamping contact. Ignitors, where applicable, are of the superposed pulse type. The luminaire is power factor corrected to a minimum of 0,9.
