Here's an unusual light. 380mm long x 24mm.
'E'9 marked, compact strip light with reverse function. Could also be used as an interior light
Pre-wired with three, 400mm fly leads. Supplied with a removable white silicone gasket / rear cover for weatherproofing. And here's the clever bit. Its slightly concave by just a few millimetres so that, as you screw them in place it'll seal in the middle first then at the ends as you tighten the screws. Nice. Fits in a cut out 347 x 18mm with 360mm hole centres.
