This discreet round recessed emergency spot downlight is provided with auto-test (self-test) to reduce the time required for monthly and annual testing. The diameter of the ONTEC C is just 90mm including the bezel and comes with a clamshell driver narrow enough to fit through the suggested 70mm diameter cut-out. With non-maintained LED lamps providing an emergency output of 167 lumens, it allows for spacing between fittings in open areas of 8.5m at 3m heights or 11.5m at 5m heights.
