Abstract
A ballast can be mechanically and thermally isolated from the mounting plate which acts as a heat sink by securing a pair of L-shaped channels to the bottom of the ballast with the depending leg of each channel being disposed in intimate sliding engagement with the flat surface of a respective C-shaped channel member which is secured to the mounting plate. Vibration damping washers are disposed between the L-shaped channel member and the C-shaped channel member to prevent vibrations from being transmitted from the ballast to the base while still permitting heat dissipation through the superimposed sliding surfaces of the channels.
