All-in-one Rainbow LED part

I saw some on e-Bay that cycle through r/g/b either fast or slow. I do not think they are the "fading to colour" type though, just cycle each colour.

That sort of thing has been around for at least 35 years. You could get blinking LEDs, albeit single color, back then. You could also get LEDs with a built in constant current source so you didn't need a current limiting resistor. IN both cases, the circuitry was on the same surface as the actual semiconductor that emitted the light.

They likely don't exist. At the very least, they aren't generic parts that you'd get in small quantities. They are specialty items cooked up for the end product. They decide they can sell enough, so it's worth creating a new device for it; after all, fewer parts means less inventory and soldering, so if it costs a tad more per device to have a special LED, the cost is recovered over the full life of the design.

If they are buyable parts, likely they are from Asia and won't appear in the local catalogs.

Blue LEDs haven't, at least in affordable form.

I suspected that but there is no harm in searching. The outdoor lamps are made in China, so I expect that your reply is on the money.

Do you recall what the auction called them? My recent searches have come up empty. I wonder what ppl are calling these things. That may aid my search.

Try adding the word 'lumia' to search terms. It isn't, exactly, but it's close enough, and the word will bring up interesting stuff anyway.

Super Bright LEDs stocks two versions of an RGB LED similar to this. I had a very difficult time finding them, myself. I had ordered a different variation a few years ago, and I cannot find that one now. The 'Fast' model on superbright just blinks through the colors at about 1hz, without fading between them. The 'slow' model fades in and out and changes colors about once every

4 seconds. They both work fine with 3V sources.

Do an e-Bay search on "rgb flash led"

I found 282 hits with that search

Thanks. Someone was also kind enough to tip that there are some here as well:
