Frequently Asked Questions

Q: What is the difference between the 5mm Straw Hat LED and a standard 5mm LED?

A: The Straw Hat LED features a wider, flatter lens that produces a broad 120° viewing angle, spreading light more evenly across a surface. Standard 5mm LEDs typically have a narrower 15–30° beam angle. The Straw Hat design is ideal for backlighting, signage, and decorative applications where wide, uniform coverage is more important than a focused spot of light.

Q: Do I need a resistor with these 5mm LED diodes?

A: Yes — always use a current-limiting resistor when connecting these LEDs to a power supply or microcontroller. Operating voltage is 1.8–3.4 V and the rated current is 20 mA. For a 5V supply, a 100–150Ω resistor is typically sufficient; for a 12V supply, use approximately 470–560Ω. This protects the diodes and maximizes their 20,000-hour lifespan.

Q: Can I use these LEDs with an Arduino or Raspberry Pi?

A: Absolutely. These 5mm F5 Straw Hat diodes operate at 3.3 V–3.4 V / 20 mA, making them fully compatible with Arduino and Raspberry Pi GPIO pins (both 3.3 V and 5 V logic). Simply add an appropriate resistor in series with each LED on the signal pin, and you're ready to code your lighting effects.

Q: How many colors are available, and are they sold separately?

A: These diodes are available in 9 colors: Warm White, White, Red, Green, Blue, Yellow, Orange, UV Purple, and Pink. Each listing allows you to select your preferred color, and packs come in quantities of 100 or 200 pieces of the chosen color.
