last update: 21/10/2025Description
Recessed luminaire for LED lamps with active heat dissipation system. Shaped sheet steel structural assembly. Painted metal perimeter contact frame. Die-cast aluminium universal joints, set back from the installation surface to optimise visual comfort, allow the luminaire to be adjusted +/- 30° relative to the horizontal and vertical axes. Die-cast aluminium optical unit. Forced heat dissipation using a fan with magnetic anti-friction operation guaranteeing lasting efficiency and maximum quietness, so that lamp performance remains unchanged. The fan has an anti-dust protection system and thermal breaker for safety. PMMA emission optic. Textured PMMA additional optic screen - flood beam angle. Supplied with DALI dimmable electronic control gear connected to the luminaire. Warm white high efficiency LEDs.
