This high quality 5 foot Link Cable may be used with our full line of exhibit lights. The shorter 5 foot length of this cable makes it ideally suited for linking lights together (i.e. linking a Secondary Light to a Primary Light or another Secondary Light). Other than its shorter length, this Link Cable is identical to the longer 10 foot Power Cable. As such, it also can be used to link a Primary Light to its power source or simply to extend the length of another cable (Power or Link Cable).
