This year for my Christmas trees I decided to use the effects from FastLed community.
The result is beautiful: pleasant and very elegant. The video does not give the real beauty of the effects.I’m using:
TimedPlaylist
TwinkleFOX which is incredible. Very impressive.
ColorWavesWithPalettes
Some other from demoreel100.
Thank to Mark! You are great!

Very Nice! What LEDs did you use?

Same question, would like to know what LEDs were used

12mm ws2811 pixel ip68. The distance between each one is about 35 cm. I put a ping pong ball as a diffuser to improve the visibility from any angle of vision. (cheap solution and good results)

Please tell me how you are running that many LEDs. If I try anything more than 100 LEDs ColorWavesWithPalettes grinds to a halt. I have 500 LEDs on my tree, 60A power supply with lots of injectors, a Particle Photon, and I’m using the same LEDs that you are using. Everything is working perfectly at 50 LEDs, but when I add more strings it starts transitioning slowly and finally just stops working. Any help here would be super appreciated. P.S. your tree looks amazing!
