The DL42-R77 is a compact LED-downlight specifically designed to be integrated into B0 or B15 fire approved ceilings. The use of fire resistant materials combined with a unique heat sink makes this downlight to the perfect choice for B15 ceilings. With the use of the DL42-R77 there is no need for any additional heat caps on the opposite side of the ceiling to keep the B15 approval. The installation of the luminaire is easy with self-tapping screws.
