LED Wall Lamp Extenders

I use the battery powered LED wall lamps. Like the ones they sell on Temu. The wall mount that comes with the lamp is fine if you are illuminating a picture, but if you want to illuminate a shadow box or wall case, the base is too short. I made this extender to properly orient the lamp to illuminate my cases. I have a short and long extender. I find the two lengths suitable for my needs so far, but feel free to adjust as needed.
