/483S First fix sleeve

First fix sleeve is polypropylene, with a finned top to fix into various surfaces.

/483N or /483N-2 Concrete housing

Must be used when specifying the 700mA fitting. The aluminium housing is used as a

heat sink which keeps the LED fitting cool through the thermal transfer of the heat

within the housing to the surrounding concrete. The housings are big enough for IP rated

connections to be made inside the housing and a second gland is available for cabling

onto the next luminaire.
