Technical Data
last update: 21/10/2025Description
Multi-lamp standard lamp luminaire. LED lamps with active heat dissipation system. Entirely aluminium frame; die-cast aluminium universal joints; can be adjusted +/- 45° relative to the horizontal and vertical axes; two extruded aluminium supporting rods with (+/- 45°) adjustable joints coupling to frame; lever-operated mechanical locks. Aluminium and steel base housing electronic control gear units and control switches. Die-cast aluminium optical units. Forced heat dissipation using fans with magnetic anti-friction operation guaranteeing lasting efficiency and maximum quietness, so that the performance of the lamps remains unchanged. The fans have an anti-dust protection system and thermal breaker for safety. PMMA emission optics; spot beam angle. Warm white high efficiency LEDs; CRI (Ra) > 90.
