Frequently Asked Questions

Q: What is the difference between common cathode and common anode RGB LEDs?

A: In a common cathode RGB LED, all three color channels share a single negative (ground) pin, and each color is activated by applying a positive voltage to its respective pin. In a common anode LED, all channels share a positive (power) pin, and each color is activated by pulling its pin to ground. Choose the type that matches your circuit design or microcontroller logic.

Q: Can these 5mm RGB LEDs be used with an Arduino or Raspberry Pi?

A: Yes! These 5mm 4-pin diffused RGB diodes are fully compatible with Arduino, Raspberry Pi, and most microcontroller development boards. Simply pair them with appropriate current-limiting resistors (typically 100–330Ω per channel) or an RGB LED driver module for full color-mixing control.

Q: How many hours will these RGB LEDs last?

A: These LEDs carry a life rating of up to 100,000 hours under normal operating conditions (within the specified voltage and temperature range), making them an extremely durable and cost-effective choice for long-term DIY projects and commercial displays.

Q: Are these LEDs suitable for outdoor billboard or signage use?

A: Yes, these diffused RGB LEDs are designed for billboard atmosphere lighting and LED signage applications. They operate reliably across a wide temperature range (-25°C to +85°C), making them suitable for both indoor and outdoor installations when properly protected from moisture and direct exposure to the elements.
