We recently got a request to make LED sequins with bright UV LEDs for costuming projects using UV-reactive paints and textiles. Also known as 'blacklight' paint or fabric, these dyes glow fluorescent when exposed to UV light.

However, not all UV LEDs will work! UV ranges from 100nm to 450nm, and some frequencies are used for curing or disinfection. For light effects, 365nm is the 'peak' frequency to look for. Let’s find a ~365nm SMT UV LED we can pick and place onto a small PCB for easy sewing. ✨🧵
