Delto LED ceiling light with direct light beam The Delto LED ceiling light is made of aluminium. Its modern, round form follows clear, soft lines without frills or unnecessary embellishments. This light is all about targeted, clear lighting without compromise. The fact that the GU10 socket is recessed into the luminaire tube means that the light beam is directed from the outer walls and emitted directly downwards. The light is thus guided and shines glare-free. With Delto, spots are set that combine to create clear lighting. The "dim to warm" function allows the light to be dimmed and its light colour changed using a light switch (not included). This means that the more you dimm, the warmer the light colour becomes. So cosy hours are guaranteed here.
