Hi all, first post
Briefly, I live on a sailing boat, have been playing around with arduinos/Pi/esp for a while and some fairly basic electronics so a bit up from newbie but not too far.
I made a constant current LED anchor light and separate on/off light sense switch a while ago which has been working really well for many many nights. Now looking at a new one with PCBs from jlcpcb. So think the first one is what questions should i be asking
So the circuit below works if I've copied it over right from the perf board version. Constant current side came from here..
Some discussion about the first version here -

The rest i sort of guessed so not sure if the FET/transistor are ideal, or any of the components for that matter.
The on/off side seems a bit busier than it should be, again i just guessed and fiddled til it worked. General idea is open source, anyone can click the easyeda link, order the boards from jlcpcb and components from lcsc and build their own.
Designed in easyeda - used the auto create tracks which seems to be bit frowned upon but probably does a better job than i could. Project here - https://easyeda.com/paddyb/anchorlightmaster_copy
Sheet1 copy is the circuit in question.
Jlcpcb do a surface mount assembly service but only have a limited selection of components preloaded hence the resister networks and double capacitors .
So does that look ok - could it be better? Are there better choices of components? LEDs will be cree 503d-wan.
Any pointers about best practice, or general pointers at all gratefully received
Thanks!
