3mm 紅色 LED（100 顆裝）

I've been using these red LEDs for a few projects and the brightness is consistent across all 100, which is rare for budget packs. They fit perfectly into standard breadboards and light up clearly for status indicators. Exactly what I needed for a simple power-on display.

Tore into the bag expecting a few duds but every single one of the 100 lit up first try. The 3mm size is perfect for my display board and the colored package gives a nice clean red glow.

The red glow is exactly what I needed for a status indicator on my DIY power supply, and the colored lens makes them easy to see even in bright light. All 100 arrived intact, and they fit snugly into a standard breadboard without any loose pins.
