Such a lamp can be used as additional illumination in a car van or for lighting a tent at night.
Moreover, it is very easy to unscrew it from one place and twist it to another.
From the burned-out choke of the fluorescent lamp, I propose to make just such a 12 V light bulb from LEDs.
It is very simple to determine a blown throttle or the lamp itself. Replace the lamp on the throttle or vice versa. So we determine what we burned out.
In my case, there was a burned-out choke. I set aside the working lamp for the next replacement.
It was a pity to throw out the throttle, and the repair was not for me.
So the idea came up with how to use the throttle further.
Carefully with a knife or a flat screwdriver, open the cartridge case.
It is necessary to open slowly, so as not to break off the latches on the case.
We take out and cut the board. From the base, you should try to leave the wires as long as possible (for further soldering the wires).
Now I took the Chinese 12V LED block. For starters, I lengthened the wires, the factory ones are a bit short.
He put the wires through the lid and fixed the block with hot glue.
On each wire I pulled a piece of heat-shrink tubing to insulate.
I soldered the plus wire to the center wire of the cap about minus to the body.
He set the heat shrink with a lighter.
Carefully fold the wires and snap the case into place.
All is ready.
