DIY LED Lamp – 30 LEDs (12 V)

This is a DIY 3D-printed LED lamp designed for makers who enjoy combining printing with basic electronics. The lamp uses 30 individual LEDs, powered by a 12 V power supply, and requires manual soldering.

The LEDs are wired in groups of 3, with one 220 Ω resistor per group, ensuring stable operation and even brightness. The internal design keeps the LEDs well aligned, producing a clean and uniform light output.
