12/24 Volt Mini LED Lamp

I designed this lamp to run off my 3D printer's power supply. It has pan, tilt and height adjustments. The lamp uses 12 volt power, or with different parts it can be 24 volt. Nominal power consumption is 3.6 watts. The power can be changed by using a different resistor, but be careful of overheating. Assembling this lamp requires soldering.

The LED gets hot, so at least the lamp casing should be printed with a high temperature filament. The diffuser should be printed with transparent filament.

The pieces mostly snap or screw together, but the pegs on the side of the lamp must be glued on.

Bill of Materials

• Cree CXA1304 series LED, 9 volt: Choose an LED with your preferred color temperature. For 24 volts, use an 18 volt LED.
• 10 Ohm 2 Watt Resistor: For 24 volts, use a 39 ohm resistor. When assembled, the resistor goes inside the tube.
• Aavid Thermalloy Heat Sink 507002B00000G
• Thermal Grease: Use any suitable thermal grease.
• Power Switch: Use any suitable power switch. I have included a printable case for the linked switch.
• Wires: Use any wires of similar size.
• Power Connectors: I used these barrel jacks and this barrel plug to connect the lamp to my printer. I have included a housing that holds two of the linked jacks, the lid of it is designed to be welded on with a 3D pen or you can or you could glue it on.
