The original style from ReallyBigLights (not sold anymore) and the newer, more popular Home Depot versions made by their Holiday Accents brand. Check your thread size to determine which you need if you're not sure what you have.  HOME DEPOT RBL adapters Screw-in threads are 80.5mm to 83.5mm  _____________________________________________________________________ OG RBLs from ReallyBigLights (these lights are no longer sold) Screw-in threads are 70.0mm to 74.0mm
