IL611 5mm Diffused RGB Controllable LED, Common Cathode (Pack of 12)

These LEDs have great colors and brightness. Easy to use, pretty good tolerance. All of mine worked exceptionally well and each color works. I am using these with an Arduino board. I tested them all with a color mixer sketch (of my own). All the mixed colors showed well, except the purple. The purple showed, but was hard to see without holding a piece of white paper behind it. Still, the LED works very well.

I've only used one so far but it has worked perfectly for my needs. I created a cable out of an old Ethernet cable and a 10 pin connector and wired the led so I could connect it to a serial port on a motherboard in a Windows PC. The LED itself is a perfect replacement for the power led in the computer case. I'm using Windows 7 with Windows Media Center and when I have a recording in progress, this led turns red. I'm also able to program it to turn other colors for different reasons. Using software called LEDsDriver by Slick Solutions and EventGhost for different events.

Decent assortment of small LED lamps.

I bought a set of these to wire up to a set of six Raspberry Pis (a 'Bramble'/cluster), and I'm using them to indicate server status using different colors. You can use PWM to set any color you'd like, or even to fade LEDs if you'd like. I also have one wired up to an Arduino for a temperature indication project as well. They all worked great, didn't include any resistors (like the picture shows), even though the printed card with the LEDs said resistors were included. No big deal; I have a box of spare resistors :) Wiring these up, make sure you have a resistor on each color leg—so 3 resistors per LED!

Really love the brightness these LEDs have. This item is for the common cathode one. Didn't know the difference between common cathode vs common anode so I had to read about them. I'm a beginner so I still don't know that much about the specifics but it was really easy to set up for my project. I also bought the common anode LEDs and for my needs I like to use them. Also read up that the common anode are overall the preferred ones to use. Bought my other LEDs from Microtivity and I love them. All LEDs that I received worked perfectly.

Work as expected. Includes a small card with the forward voltages of each of the three colors. Very bright. I only wish it was slightly more diffused as with the high brightness comes visibility of the junction of each of the three colors at times, particularly when attempting to simulate yellow and orange.

These LED's are very well documented and are very easy to use (comes with documentation). But you can get 50 of these for less money. If you are new to using LED s these are documented well and right for you, but if used them before its a waste of your money

They came packaged exactly like in the picture. All worked, but I popped one fairly quickly. They served their purpose perfectly. Just make sure you know you want the 5mm diffused. If you are not familiar with LEDs, viewing angles play into the "relative brightness" (how bright it is when you stare at it). The diffusion makes the angle wider and actually makes looking straight at these LEDs running at full juice somewhat bothersome to my eyes. If you are looking for LEDs to incorporate into something you will often be looking at, I would recommend surfing for some clear cap ones.
