Modular Lamp v1.4 for 12v G4 - A+++

thingiverse

This is just working progress. Here in Italy, a light bulb costs about 10 euros and every bulb has a power transformer inside. If your house has 20 bulbs then you have 20 power transformers. My idea is to create a 12-volt lighting system that works off the grid and costs less than a single bulb. On Amazon, you can buy ten packs of 3.5-watt light boxes and ten holders for less than 25 euros (less on Bangood). With ten bulbs, you can make five lamps and illuminate a 15- to 25-square-meter room with a single 12-volt 3A power supply (10 euros or less). The plastic part accounts for about two-thirds of the price in PLA. For around six euros, you'll have a fully functional light to hang on the wall - not a single light bulb. For the knob, I used an M5 bolt. Simply push nuts and bolts into the plastic and screw them together. I use a vinyl mirror sticker to increase the amount of light, but this is up to your personal preference. For the joint, I used a 32 x 5 mm circular neodymium magnet and two M5 bolts. In this way, the two pieces stay together but can rotate at the same time. More to come...
