12 Volt 5Mm Pre Wired Led Light Emitting Diodes,Micro Led Lights Diodes for Model Assortment Kit,12V Mini Single Led Bulbs(Red*10,Green*10,Orange*10,Blue*10,White*10)

I tested each and every one of these with a 12V power supply. Every one works and is the correct color (there are 5 bags of 10, each bag marked with the LED color). To the one-star reviewers who complained that not a single one lit up when tested with a 1.5V AA battery.... all I can say is "it's better to keep quiet and be thought a fool, than to open one's mouth and remove all doubt". Your LEDs were probably perfectly fine, as mine are - but you didn't provide enough voltage to light them up. LEDs are nonlinear devices and the closer the blue you get the higher the voltage needed to wake them up. A red or yellow LED might glow faintly with a 1.5V battery (you'll have to turn off the room lights to see), but green, blue or white (which is similar to blue electronically) won't do a thing at that low voltage. You're better off testing with a 3V coin cell, or better yet a 12V source (which is what these are designed for). So don't be swayed by the one-star reviewers who don't know what they're talking about. These LEDs work fine.

Bright LEDs with a great variety of colors. Appreciate that the diodes are already heat shrunk in line with the LED. Holders were tough to fit into the plastic project box I had but I think that was more the hole on the box was the incorrect size. Overall great value for high quality LEDs

I bought these for my son’s school project. The work great! Easy to work with for a beginner because each LED light has resister attached to it. If you have proper power supply circuit works well. All LED’s light up in a bright vibrant way. I am really happy about this product.

Great for homeschool tech projects! My son loves learning how these work!

Works great

A great set of LEDs for our grand kids projects

Good led so far. They are normal brightness. The red is a little dim and the yellow is actually amber. But they worked for me

Then light are just right size love them and the right size I needed and at a very good price and nice and Brite

easy to use , no need for a resistor

Me encanta el modelismo y es lo adecuado para mi. Funcionan al 💯👍
