Astra 3 can accommodate 250W/40OW HPS, 250W/40OW MBI and 250W MBF lamps. Astra 3 is suitable for illuminating streets, roads, highways and car parks. Suggested moun¬ting height: 6-12 meters for 250W and 9-16 meters for 40OW
ELECTRICAL: The control gear box is provided with a 3-way terminal block. High temperature silicon insulated conductors are used throughout. Electrical connections are made quickly via a plug and socket system.
MECHANICAL: Astra 3 has been designed for ease of installation and maintenance. Both post top and side entry is possible by reversing the mounting bracket. The canopy and lamp compartment are hinged to the body and are fixed by a stainless steel screw. The canopy hinges up to the body to access to the gear compartment. The quick release gear tray can be removed for maintenance without disturbing the lamp or lamp holder. Once in position the bowl or glass cannot be accidentally detached as a screw driver is required to release them. After lamp insertion, -~e bowl or glass is hinged and fixed into its sealed position by means of two stainless steel clips. Hinging down the bowl (opening the lamps compartment) is equally simple, just by removing the two clips and bowl hinges down.
