I wanted a lamp to light up a room when the power goes out that will run off of my battery box I made for ham radio, I could have done an inverter and a 110v lamp but that is inefficient so I went with 12v LED strip lights and a buck converter to drop the 14v down to 12v.
If you connect the LEDs straight to the battery the 14v is too much for them and they get hot and start to dim.
I added a half height mini version as well.
I printed the base out of ASA but anything works and I printed the cover out of clear PLA but clear PETG would also work.
I printed with supports, I printed the cover in the upright orientation so that the outside would turn out perfect even though it wastes plastic on supports, it was worth it to me.
If printing upright use a brim too.
I soldered all the +s together and all the -s together then soldered them to the output of the buck converter, I then hooked the - of the powerpole to the buck converter, the + of the powerpole to the switch and then from the switch to the buck converter.
