Dragon lamp different base

I made my own Base, because the original used lamp was not available anymore.
So i made the base for these lamps : https://tinyurl.com/2e75fshz
just drop the bottom part of the lamp and insert it to the base.

As these lamps run with 4,5-5v, i decided to add a cable gland, that i can dispense with
the batteries and connect an USB cable
