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)

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

Happy I got them

Awesome

Excelent

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.

good value

Great for custom light projects small or big, work great for custom colors on rc cars

Good LEDs for the price. The holders aren't sized or constructed to hold the LEDs in very well. Once the LED is inserted into the holder, trying to compress the legs together and insert into a pre-drilled hole is near impossible & the LED doesn't stay locked in anyway.
