DiCUNO100pcs 5mm RGB Multicolor Fast Blinking LED Diode, Multi-Color Blinking Changing Light Emitting Diodes, 2 Pins Clear Round Lens Diffused Flicker Electronic Components Circuit Lights Kit

The media could not be loaded. Though I don't know what I'll do with all of these, I did use one in a wand that I made, and it really came out nicely. I found that two button cell batteries will power one, and I'm sure if I do more experiments with these, I can find more uses for them, and better ways to power them. All together this is one heck of a deal.

The media could not be loaded. This is one of those times the item FAR EXCEEDED expectations. I really wish my lousy video showed the colors, but for reasons I don't understand it seems to be just washed out white. Maybe they are too bright for the sensor, don't know. But these things are extremely colorful, and just a delight to watch. The speeds change, and the colors rotate satisfactorily.Although these are supposed to tolerate up to 3.4 volts (DC), I am using an 18650 battery (installed in the homemade double decker "Santa Caboose) that is charged to 4.17 volts. ( It is also running an LED light strip in the car). I tested the lights before I made the car, and they seem to tolerate the higher voltage just fine. ( I used an 18650 because of the superior power and longevity)The legs that connect to power accept solder readily, and are easy to bend to whatever configuration you need them in.I'm almost hesitant to heap too many accolades on this item, 'cause I may buy more for other projects and I don't want 'em raising prices. But heck, at $8 for 100 of these, it's was beyond a bargain !These are just some of the best things I have ever bought, fun to build, watch, and plan projects with.

These little lights are amazing in any diy project they change colors and are extremely bright, the only thing that I regret is that I didnt purchase both the fast and slow switching so now I have to put in another order

Bought these to fix a small fiber-optic xmas tree that had a burned-out motor. 15 of these guys at 12 mA each took care of the lighting. The color rotation seems to have only a brief red phase. The tree is mostly blue/green but hey it works.

The media could not be loaded. Very good product. This is just one of my Creations I made using the lights I purchased. Everyone that has seen it has had nothing but good things to say about it. I used the slow fade and was very happy. Quick shipping as well.

I bought these to drop into jack-o'-lanterns at Halloween but now one tops our workplace Charlie Brown Christmas tree. They're brighter than you'd expect and have such a low draw that a 3V button cell powers it in the pumpkin for more than a week. Just snap up a box and toss them in a drawer in the garage. You'll find a use for them.

Great price for that quantity

I used these to replace the LED in each of two mini, color-changing Christmas trees. The original trees where flickering and sputtering after a couple of season's use. The original trees used 18 ohm series resistors powered by USB (+5V). Measurements I made show that a 56 ohm resistor is necessary to keep the current draw to 20mA max specification, so I think that is why the original trees failed. I replaced the LEDs with these and the series resistor with 56 ohm and the brightness is fine and expect them to last longer, too.

this product is really awesome and my son does lots of projects using this, thank you
