Buck Wiring

[girdles]

Can anyone tell me what side of this Buck the power goes in and what side led connects to please?

Thanks in advance.

hi dean

id say the input from the batteries would be the ones with + - on them nxt to the PWM input pads, the other pads by the inductor would go to the LED.
it seems other buck drivers have the inductor on the output line, so i think this should be correct.

also i think the K and A stand for cathode and annode, which would be the LED neg and pos


decided what to do with that HID yet?

Hello John
hope your well and diving.
HID got busted at Scapa, being replaced by 4 x xpg r5 leds from led tech.
Thanks for the info on the Buck.

See you soon maybe on one of beavers hard boat dives.

im good thanks dean, getting a few dives in here and there, mostly at chepstow. Im taking things easy these days.

what optics are you trying for the xpg's

Got ledil 9 degree optics the led pcb is meant to be 1480 lumens, it dont seem as bright as 10 watt HID

all depends on how its focussed i think, wider beams will look less bright then a pure spot.

This is it, Crude but works.
I get the MEG head back this week, I will dive it, then decide if theres too much spill compared to the HID.
