Low voltage garden lighting, looking for just the lighting element and wire

My front garden has the Hampton Bay low voltage lighting.

My wife recently bought a stone Japanese lantern, and I thought it would be cool to have it light up with the garden lights.

Hampton Bay, really Home Depot, doesn’t sell just the lighting element, at least not from what I can see.

Anyone have an idea of where I can get just the low voltage LED light that I can connect to the low voltage wire running through my garden? I’d like to avoid spending money on the entire fixture that I’m just going to break open and take the light out of.
