Ring lights used to just be a fun type of portrait lighting style, but now are becoming more and more popular for YouTubers and vloggers who need a soft, even light on their face for a camera that sits close to them. Caleb Pike from DSLR Video Shooter is a self-proclaimed do-it-yourself enthusiast, and made this tutorial on how to make a light that is similar to a ring light, but creates a triangle shape instead of a circle.
As you might have guessed, this source of light in this DIY comes from LED strips, but Pike gets into how he mounted, wired, and installed a dimmer into the final unit. You'll need some basic tools like a soldering iron, drill, and maybe a small saw if you wanted to cut some small pieces of wood to replicate his project. Lots of other options might exist if you have access to something like a 3D printer, for example.
Powering the unit comes from a small 12V battery unit. While it might not have a ton of throw, this is pretty novel for a low-cost, battery-powered solution. In all, this cost Pike about $92.
In case you missed it, our own Fred van Leeuwen recently wrote a pair of articles about making DIY light modifiers.

Great stuff! How much amps do the lights draw at full brightness? If it really would be 2A at 12V (but I doubt that) then that translates in at least 4.8A at 5V, which most powerbanks will not supply. Depending on the quality of the powersupply you may damage your powerbank (or worse, the usb port of some other device).
