acrylic material provides chemical resistance while the u201c frosted u201d properties of the overmolding material provide additional light refraction to the led array 13 approximately 84 or better light transmission may be achieved a preferred embodiment light lens assembly is illustrated in fig3 12 this assembly is generally similar to the embodiment shown in fig1 2 with some improvements in particular the embodiment of fig3 12 includes an adapter ring 61 shown in detail in fig8 to 10 the adapter ring 61 permits installing the light lens assembly of the preferred embodiment into larger holes which previously accommodated prior art light fixtures thus the adapter ring 61 is used in retrofitting older spas with improved apparatus provided according to the invention in such applications the ring 61 is glued to the spa wall surface the adapter ring 61 has a central circular opening 63 sized to fit over the hub 133 of the wall fitting 115 the back surface 163 of the bezel component 123 abuts an outer ring surface 165 of the adapter ring 61 as shown in fig6 and presses the surface 165 into the spa wall 17 when the assembly is installed as particularly seen in fig1 the wall fitting 115 has a depression 168 formed at a back edge thereof which provides a glue well which is employed in gluing the wall fitting 115 to the spa wall when the wall fitting 115 is initially installed thus both gluing and bezel pressure are used to hold the assembly in.
