Hi guys ! We are working on a project that we will release open source in a couple of months (www.luxontower.com), but we are having a problem. Right now we are using these leds with a custom PCB, but we would need surface mount RGB leds (and with flat head) that are as powerful as the leds that we are using right now. I search, but I can’t find anything that doesn’t cost like 14$/led.
Neopixels are really bright, that might be worthwhile trying. This uses those: https://www.youtube.com/watch?v=Rul0JDoE6CE
This one as well apparently: https://www.youtube.com/watch?v=KlH0vFRyuBM
If your looking for the same 6000-8000 mcd (if that’s what the ones you have really put out) it’s going to be a fairly expensive part. On the cheaper end with a standard 5050 type surface mount rgb your probably looking more in the range of about ~1000 mcd that’s about what something like a neopixel (also known as a 2812B) puts out as well. You could possible compensate for the loss in brightness with quantity but I’m not to sure that would require testing to see if it was sufficient
On other thing to consider is that something like a neopixel is not a common anode type of LED, it is a single data input LED and as such the way you address them and change colors will need to be taken into account.
