Made 12V LED lamp from broken AC lamp.

Press more for description

Schematics. LM317 in current stabilisator mode. SMD 0,5W LEDs 5730 Are used.

The power of the glow is enough to illuminate a small room.

Later I made a USB version.

It is possible to power it from powerbank. Both options are suitable for use in hiking, or when the power is off at home.
