Path Lighting - Top Dog Scotty Mini Twinnovator vs Mini All-Star™ Twinnovator vs Mini Round Wash Pat

The mini Round Wash light description says up to 13 ft of forward light. I have a long (approx 50 ft) narrow (10' to 12' depth) back yard with pavers (fenced in) - I would like to like light the pavers from both directions - what is the approximately forward lighting of the Top Dob Mini and the Mini All Star w/ 2700 K bulbs of the three different "W's". I'm trying to estimate the appropriate light and the need for another in the middle or two others. Thank you. I let my dogs out after dark and recently had a diamond back rattlesnake (coiled and ready to strike) on the pavers - the dogs saw it first and barked fortunately before I let them go out on their own

 

A photo (or even a sketch of your yard would be helpful). Landscape lighting is a visual medium and it might help people better understand what you're trying to accomplish and how best to accomplish it.
