Garden Light LED's WL83AP “well light adapter plate” allows the installer to turn an ordinary S2 into a Par36 sized light. This can then be used in our standard halogen line of WL1047, WL1048, and WL1049 PVC well light fixtures. After attaching the S2 to the adapter plate using the screws supplied with the standard S2, The assembly can be “snapped” into the PVC well light fixtures just like a normal Par36 halogen bulb. This is great for upgrades also, Instead of replacing burned out par36 bulbs; a S2 with adapter plate can be put in its place upgrading an old power hungry halogen system to LED!
