(100 Pcs) MCIGICM 5mm LED Light Diodes, LED Circuit Assorted Kit for Science Project Experiment (Multi-Colored - 5 Color)

A good value. The colors are great.

I got all 100 LED's1 x Red did not work, it died DOA.4 x Yellow LED died because I burnt them out, I didn't have resistors at the time but after getting resistors and testing they seemed to work just fine.I suspect the red was my fault to for not having the correct resistance in place.Overall I'm happy with the product at this price point it was worth it.

Lights were great but the blue and white ones, lots didn’t work and had to throw out.

I have looked for many LEDs for my mechanical kits. These are affordable and work well. Some of the LEDs didn't work, which is fine for me. Their colors are great, the brightness is acceptable, and they're easy to operate.Recommend them.

At the end of the electricity unit my students had to create a light up. Card This was affordable and all work properly!

These were exactly what I was needing. I was happy with the brightness. I was sending about 18 mA through the LEDs and the yellow LEDs were too bright to look at for my eyes. Good value for the money.

I have had several so far that either doesn't light up at all or is extremely dim to the point they are useless

I purchased these for a child’s science fair project. They worked fine although I was not aware that the yellow ones were a lower voltage. Overall they got the job done.
