CHANZON 100 pcs 5mm RGB Multicolor Diffused LED Diode Lights Common Cathode

Please note that these RGB LEDs have three individual LED devices inside, so if you buy the clear version you will see three individual colors. The frosted version (which is what I bought) mixes the colors better. Also, be careful as to the polarity, these are Common Cathode but the seller also offers Common Anode versions, which are NOT interchangeable!

These are COMMON CATHODE RGB LEDs. Perfect for my purposes (wiring up to an Arduino and/or Ultimarc's LED controller boards), but if you're shooting for use with a common-anode based RGB light controller, or the LED-Wiz boards from groovygamegear -- you'll need to get something else. Super bright. Had this wired up to PWM control software on an Arduino, and I had to put something between me and it just to look at it. You CAN tell that the voltage/current sensitivity of the R, G, and B elements differ, but that's pretty typical with RGB LEDs. I haven't really found any affordable (aka CHEAP) RGB LEDs where the R,G,B elements were more or less balanced. It's just the nature of this beast. Considering getting these from Mouser/DigiKey would have cost upwards of $100, I'd say this was a darn good value!

I got the 5mm RGB common Cathode LED. The Green element is super bright and required a higher resistor value than R and B (to balance out colors). II designed a Printed Circuit Board to solder this LED on and I'm glad I only ordered 20 boards: The center-to-center lead spacing is incorrectly called out on the mechanical drawing as 1.0 mm when in reality it is 1.25 mm. It is not impossible to fit the parts in but it takes much longer to solder them properly. I'm going for PCB revision 1.1 now. Everything else works fine.

These have 3 colors and are bright (depending on resistors)

Have used as many as 24 at a time, and all work well. Appreciate the voltage label for each color on the bag. Only challenge is shades of yellow: the red & green together bleed red & green, i.e. look separate instead of combined (no such issues with magenta or cyan); wonder if diffused is the way to go. Good for learning the basics.

colors mix very well

Super easy to use, and bright enough that you cannot look directly at them using and Arduino and 2 18650 cells.....

Great set of RGB leds at a very affordable price.

Very good product

Preisgünstige LEDs mit guter diffuser Abstrahlung

Quick delivery and great quality LED's. Not the cheapest online but worth the extra bit.
