The rough gem  is the same device as the Gem But in a rugged, watertight enclosure for use in exposed locations - or where no pre-existing light fitting is available.

Both types produce a wide-angle beam (90 degrees) suitable for floodlighting at close range. Typical applications include interior dome lights, foot-well illumination, luggage and engine bay lighting. In particular the ruggedised version is also ideal for 'filling-in' gaps in underbody lighting such as around the insides of wheel-arches. It will also find plenty of uses on Motorbikes.

The Plug'n'play version can pick up its power directly from any suitable light fitting but also comes with a detachable cable that can be used to provide power and/or data for linking to ICELED controllers. The rough gem has a fixed cable for supplying power and optional data.
