This is the body of the ring light, the brightness will be controlled with a potentiometer which you can see in the images below, I do worry that I may not be able to drop the PCB in but if that's the case then I can make some modifications, I didn't have space for screw holes in the LED ring so I will have to use a friction fit or rely on the translucent diffuser/lens to hold it in place. This is just the first version though so I don't expect it to work smoothly, ill definitely need to cut, file, and melt some areas.

When I get a PCB assembled I will look at the output, interested to see if the compact design increases the frequency and produces a cleaner wave.
