100pcs 5mm F5 LED Bulbs – Red Green Blue White Yellow DIY

100-Pack 5mm Super Flux LED Bulbs for DIY Projects & Decorative Lighting

Light up your next DIY build with this versatile 100-piece pack of 5mm dome-lens LED bulbs. Available in Red, Green, Blue, White, and Yellow, these super-bright flux diodes are engineered for makers, hobbyists, and electronics enthusiasts who demand reliable, long-lasting illumination. With a water-clear lens and a wide 110–120° viewing angle, these LEDs deliver vivid, uniform light for every project. Made in Mainland China.

Key Features

• Wide 110–120° Viewing Angle – Broad spread of illumination ideal for displays, signage, and accent lighting.
• Super-Bright Output – Luminous intensity up to 3,000 mcd for vivid, eye-catching results.
• Water-Clear Lens – Maximises light transmission and true colour rendering.
• Durable Spiral LED Chip – Long-lasting performance across thousands of hours of use.
• Easy Polarity ID – Clear anode/cathode markings make installation fast and straightforward.
• Low Operating Voltage – Runs at approximately 1.9–3.4 V, 20 mA, making it compatible with most microcontrollers and DIY circuits.
• CCC Certified – Meets mandatory safety standards for electronic components.

Specifications

Applications

• Arduino, Raspberry Pi & breadboard circuits
• Billboard and advertisement sign lighting
• Architectural and interior accent lighting
• Holiday, event, and exhibition decorative displays
• Emergency and security indicator lights

Frequently Asked Questions

Q: What colours are available for these 5mm LED bulbs?

A: These 5mm flux LEDs are available in Red, Green, Blue, White, Yellow, and Warm White. Each pack contains 100 LEDs in your chosen colour, perfect for colour-coded DIY projects or single-colour decorative lighting displays.

Q: What resistor should I use with these 5mm LEDs on a 5V Arduino?

A: For a 5V supply and a forward voltage of approximately 2.0–3.4 V (varies by colour) at 20 mA, a 100–150 Ω resistor is typically suitable. Always calculate: R = (Supply V – LED Forward V) ÷ 0.020 A, and choose the nearest standard resistor value above the result.

Q: Are these LEDs compatible with breadboards and standard PCB designs?

A: Yes. The standard 5mm through-hole leads fit perfectly into breadboard tie points and standard PCB holes spaced at 2.54 mm, making them ideal for prototyping, Arduino projects, and custom circuit boards.

Q: What is the difference between these dome-lens LEDs and piranha (super-flux) LEDs?

A: Standard 5mm dome-lens LEDs have two leads and a rounded top, offering a focused or wide beam depending on lens design. Piranha (super-flux) LEDs have four leads and a flat top, offering an even wider viewing angle and higher brightness. This pack includes 5mm dome-lens styles that combine the ease of two-lead installation with a broad 110–120° viewing angle.
