Frequently Asked Questions

Q: What colors are available for these 3mm flat top LED light beads?

A: These LEDs are available in Warm White, White, Red, Blue, Green, Yellow, Orange, Pink, UV, and a Mixed pack (Red, White, Blue, Green, Yellow). Simply select your preferred color at the time of purchase.

Q: What voltage and current do I need to power these 3mm LEDs?

A: These LEDs operate with a forward voltage of 1.8–3.4V and a recommended forward current of 20mA. Always use a current-limiting resistor in your circuit to prevent damage and ensure optimal brightness.

Q: Are these LEDs suitable for outdoor decoration projects?

A: Yes — these flat top LEDs are widely used in outdoor signage, billboard displays, and building decoration lighting. For outdoor use, ensure your enclosure or project provides adequate protection from moisture and direct weather exposure, as the LEDs themselves are not individually weatherproofed.

Q: What is the difference between the 500-piece and 1,000-piece packs?

A: Both packs contain the same high-quality 3mm flat top LED light beads. The 1,000-piece pack simply offers greater quantity, making it ideal for larger projects, bulk DIY builds, or stocking up for multiple applications at a better value per unit.
