last update: 21/10/2025Description
Recessed luminaire for LED lamps with passive heat dissipation system. Shaped sheet steel structural assembly, which can be fitted flush with the false ceiling using a specific adapter supplied for thicknesses of up to 12.5 mm. Die-cast aluminium universal joints; luminaire can be adjusted +/- 45° relative to the horizontal and vertical axes; mechanical aiming locks. Die-cast aluminium optical assembly. Shaped to allow heat radiation so that it is effectively carried away, guaranteeing that the performance of the lamps remains unaffected. 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.
