100Pcs 5mm Green LED Diode F5 LED 3V 20mA Diffused Round LED Indicator Light for Arduino DIY, Breadboard, Scientific Experiments

This set of green LEDs is a great value. At 5mm with diffused lenses, they give off a nice, even glow that isn’t too harsh but is still plenty bright for indicators, small lighting projects, or DIY hobby builds. The color is vibrant, and they all tested consistent with no bad units so far. They run well at the rated 3V/20mA, and I’ve paired them with different resistors depending on my projects without any issues. The legs are sturdy and solder easily to PCBs or breadboards, which makes them beginner-friendly as well. Having 100 in a pack means I don’t have to worry about running out anytime soon. For the price, you really can’t beat the reliability, brightness, and quantity. Highly recommended for makers, electronics projects, or anyone needing a bulk supply of indicator LEDs

I bought the OWOFYDR 100-piece 5mm red diffused LED diodes and they’ve been a solid buy. The LEDs are bright and uniform — no weird dim ones or odd colors mixed in. The diffused lens gives a smooth glow instead of harsh pinpoint light, which is exactly what I wanted. The lead wires are long enough to work with breadboards or soldering without needing extenders. Each LED holds up in basic circuits; I didn’t see any burnouts or poor performers among the pack. The voltage and current specs matched what was listed (around 2 V, 20 mA). Packaging was simple but practical — loose in a sealed bag with labeling — it’s not fancy but it works. For projects like Arduino builds, indicator lights, custom lighting, or DIY displays, this is a great value pack of reliable red LEDs. Five stars.

These LEDs work great and do slowly change colors fading from one to the next. I used these in some battery powered tea lights to change from the white light to multi colored for a project. I can't really think of much to say about them besides they are exactly what is written on the page. They're nice and bright with one cr2032 battery but not really bright enough to see very well outside in the sun, they're better suited for indoor projects. Definitely worth the money.

Work great in a paper circuit card for Thanksgiving.

An easy LED replacement for our string lights!

Very bright, good color, correct size

The OWOFYDR 100pcs Red Diffused 5mm LED Diodes are designed for various electronic applications, from indicator lights to DIY circuit projects. These frosted round LEDs operate at 2V and 20mA, making them efficient and easy to integrate. Tested across different projects, including indicator panels and basic circuits, these LEDs deliver consistent and visually appealing performance. Pros: ✅ Bright and Even Illumination: The frosted lens diffuses light evenly, reducing glare and providing a smooth, uniform glow. ✅ Energy Efficient: Low operating voltage (2V) and current (20mA) ensure minimal power consumption. ✅ Dimmable Functionality: Compatible with dimming circuits, allowing for adjustable brightness levels. ✅ Durable and Long-Lasting: Reliable performance over extended use without noticeable degradation. ✅ Versatile Quantity: The 100-piece pack provides great value and is ideal for large-scale projects or stocking up for future needs. Cons: ❌ Fragile Leads: The thin leads require gentle handling during soldering to prevent bending or breakage. ❌ No Polarity Marking: Lack of clear marking on the LED body makes it slightly challenging to determine the anode and cathode for beginners. Performance and Usability: These LEDs performed reliably across a range of circuits, producing bright red light suitable for both indicators and aesthetic applications. The frosted lens significantly improves diffusion, avoiding harsh hotspots. Soldering was straightforward, though the thin leads necessitated extra care. Dimming functionality worked smoothly with pulse-width modulation (PWM) circuits, providing precise control over brightness. Comparison: Compared to other 5mm red LEDs, these diffused variants stand out for their smooth light distribution, making them superior for applications where uniform illumination is essential. While premium options may offer thicker leads for easier handling, this product strikes an excellent balance between quality and affordability. Who Is This For?: This LED pack is perfect for hobbyists, students, and professionals looking for efficient and versatile lighting components. It’s especially suited for projects requiring diffused lighting, such as control panels, prototypes, or decorative displays. Conclusion: The OWOFYDR 5mm Red Diffused LEDs are a dependable and affordable choice for a wide range of electronics applications. Despite minor handling challenges with the leads, their energy efficiency, even illumination, and dimmable functionality make them a valuable addition to any electronics toolkit.

Very good LEDs. I used them to add flair to my marine speakers. I drilled and installed these into the speaker covers. Make sure you completely seal/cover the exposed legs and solder joints with silicone or epoxy.

they are red LEDs. they emit red light just grand

a) They work fine. b) The 3mm LED's are about the same brightness as a 5mm LED.

Nice and bright

Product showed up on time and intact, they work and look awesome

Very good
