This warm-white glowy letter employs COB (Chip On Board) LEDs typically found in Edison-like bulbs, creating a bright, warm glow. The design uses numerous micro LED diodes bonded on a sturdy metal backing, all protected by a silicone coating.
Although LEDs are only on one side, the thin PCB substrate achieves a slight glow through the back. These LEDs are parallel wired, needing just 3V to light up. For optimal performance, pair them with a resistor to cap the current at 100mA. Not flexible, but they deliver a uniform glow comparable to tungsten filaments.
Lightweight and versatile, they can be glued, sewn, or tied to various surfaces, making them ideal for crafting words or patterns. They are easy to PWM dim and powered by simply connecting to both ends. If there’s no light upon connection, reverse polarity as a solution.
Compatible with Arcade Button Quick-Connect Wire Pairs or soldering directly to the tabs, these LEDs offer a user-friendly experience while achieving sophisticated lighting effects.
