Cheap grow lights are great – they’re energy efficient, ubiquitous, and the design pattern of the aluminum-backed PCB for dissipating heat is well chosen. However, unshielded high-output LED’s are a real pain on the eyes.
I bought a set of these grow lights to give the plants in my bedroom a little boost since their window faces a shaded courtyard in the center of my building. Rather than invest in something more expensive or put up with hot pinpoints of light stabbing my eyes every day, I designed a cheap printed diffuser to make the system more hospitable.
You can download the design files and read the build instructions on Thingiverse.
As a bonus, they also provide some great Miami Vice lighting, just in case I wanted to film my own episode of ContraPoints.
