DIY Portable Ring Light

Step 1: Step 1

I started with the plastic top from some blank CDs

Step 2:

Divide the surface into quadrants. I used a lens hood that came with my lens to trace out the hole for the lens. Put about 10 LEDs per quadrant

Drill out the holes and cut out the middle

Step 4: Step 4

Paint it. Make sure you use a spray paint that works with a soft plastic

LEDs in all the holes
