Pegasus is the only model with a physical glyph ring โ it needs all three strips:
Total: 116 LEDs โ 1.2m minimum. Buy a bit more (~1.5m, as sold on the listing above) so you can route around the strip's factory solder joint โ it must not land inside the glyph ring, which needs perfectly even spacing.
