Just out of curiosity, I took my ring path light to the garage (took the batteries out) and tested it with a 12 volt 7 amp battery and the ring path light did come on (after about a 2 second delay). Again, I am not worried about the warranty, but it would be nice if you could wire it so that all the features worked and you could eliminate the batteries. Ring, if you listening, design the same light but make it work with the Ring Transformer.
