A lighting apparatus for installation in a lamp housing incorporates LED assemblies arranged between front and back plates at spaced apart locations. Each LED assembly has a high-power LED mounted to the back plate and oriented to emit light toward the front plate, an annular spacer having a bore therethrough, and an optical lens positioned to receive light emitted by the LED and to direct the light toward the front plate. The spacer is positioned such that at least a portion of the LED protrudes into an upper end of the bore, and a portion of the lens protrudes into a lower end of the bore and is loosely received therein to permit limited relative movement between the lens and the spacer.
