Adapter ring that turns an MR11 into an MR13. Works with various fixtures. Tested on older sailboat mast lights from Forespar(?).

MR13 LEDs are hard to find! This ring converts an LED MR11 bulb into something that closely resembles the dimensions of an MR13.

Pay close attention to the dimensions in the image and verify that the ring will fit your opening.

Not for use with halogen.
