Low Power Grow Light

thingiverse

This is a versatile box designed to create a small grow light, offering either a 2:1 or 5:3 ratio of red to green. Theoretically, the large version with six red LEDs should function properly with a 12V supply, but in practice, it didn't shine very brightly at all. I'm including a 12V option. Your diodes will likely vary in forward voltage, so you'll need to perform your own resistor calculations. It features a slot for a standard tiny JST connector that can be glued in place, along with a small compartment for connecting wires. I'm also providing a stand. The stand is a hastily assembled piece and isn't ideal. You may want to use putty to ensure the lights remain secure if you decide to print it. The stand requires an M3 screw to assemble. The case itself demands two M3 screws as well. You can flip the lid upside down if you prefer to place the supports in the screw holes instead of on the sides. Here's a video demonstrating how I wired up the electronic components. https://www.youtube.com/watch?v=qgkW6qDAbeQ
