I want a rgb led , i hope 3 watt is enough brightness, something fairly bright and narrow angle is best,
and smaller = better ~1/2"-1",
+ cheap!
...fast shipping (2week)
i just want it all!~
think i found this:
https://ca.mouser.com/ProductDetail...EpiMZZMtKo6xK7%2bVI1pEltFN%2brIPGi24lrIjqzGU=
but i wonder do i need heat sink for this one, how big?
also it always gets me with the different volt inputs, 2.4 V, 7.2 V, 3.5 V, I will need to start with 12v battery, how should I apply voltage step down per channel? at cathode i will have mosfet for microcontroller~still selecting
~have lots of these:

what is path of least resistance!?
