The Supa-LED Switch Light is a small battery-powered LED light that you switch on by pressing it, the kind often called a push light or tap light. It can be stuck or screwed inside cupboards, wardrobes, caravans, tents, sheds and under stairs where there is no wiring, giving instant light where you need it. It runs on three AAA batteries, which are included in the blister pack. We could not find full specifications for this discontinued item, so light output and runtime are not listed.
