As this (https://www.youtube.com/watch?v=jGvMS9RyAyA) strip is underneath the loft bed of my daughter, where she can’t see it while falling asleep, I made her a small toy to take anywhwere she wants. Its battery (9V) powered and as the Pro Trinket only permits 150 mA power drainage, having the power functions in FastLED is a live saver! 
Thank you guys for FastLED!
And any suggestions for better filming these very bright LEDs are welcome! :-}
