Abstract: An electrical assembly adapted for use with a luminaire includes a housing formed of metal and having an interior surface defining a cavity therein. The electrical assembly further includes an unimpregnated ballast which is oriented within the cavity and which has coil leads projecting therefrom, the ballast encapsulated within a thickened mixture of curable thermoset polymer resin and finely divided inorganic particulate. the finely divided inorganic particulate and the thermosettable polymer resin is preferably provided in, respectively, a 3:1 ratio by weight.

Abstract: An apparatus (10) for maintaining an electrical component (22) in a substantially fixed position relative to a base (24) in an electrical assembly, the apparatus (10) being electrically isolated. The apparatus (10) includes a component retention portion (12) adapted for contact with the component (22), a base retention portion (14) adapted for attachment to the base (24), and a variable portion (16) between the component retention portion (12) and the base retention portion (14), the variable portion (16) being adjustable to the size of the component (22).
