Frequently Asked Questions

Q: What colors are available for these 5mm flat top LED bulbs?

A: These F5 5mm flat top LEDs are available in nine colors: Warm White, White, Red, Green, Blue, Yellow, Orange, UV, and Pink. Simply select your preferred color when adding to cart.

Q: What resistor should I use with these 5mm LED bulbs?

A: The appropriate resistor value depends on your supply voltage. For a common 5V supply with Red/Yellow/Orange LEDs (forward voltage ~2.1V at 20mA), a 150Ω resistor works well. For White/Blue/Green/UV/Pink LEDs (forward voltage ~3.1V at 20mA) from a 5V supply, use approximately 100Ω. Always calculate using Ohm's Law: R = (Vsupply – Vforward) / Idesired.

Q: Are these LEDs compatible with Arduino and breadboard projects?

A: Yes! The standard 5mm through-hole lead spacing is perfectly compatible with standard breadboards, Arduino boards, and PCBs, making them ideal for prototyping and DIY electronics builds.

Q: How do I identify the anode and cathode on these LED bulbs?

A: The anode (positive terminal) is the longer leg, and the cathode (negative terminal) is the shorter leg. Connecting with correct polarity is essential for proper operation.
