I’m working on an installation of lights in a spiral. I made a little app to help me calculate how many lights and how long a strip I’ll need. Maybe it’ll help someone else out there too 🙏

You enter how wide you want the spiral to be (in mm), and how far apart the LEDs are (in standard increments). It will give you back the length of strip you need, and a list of points for your mapper.
