Hello everyone,
I recently started a project out of pure boredom. Its one of those 100w budget lights diy.
Everything went fine, until I completed it and did some measurements.
The scheme is super simple:
12v (5Ah) lead battery (salvaged from ups) ->10A fuse -> 20A Switch -> "150W" chinese booster that changes voltage from 12V-34V -> LED COB forward voltage 34V, forward current 3A
(there is also separate circuit powering fan to cool this thing down)
When powered everything works perfectly, untill I checked the current.
Battery to booster is almost 15A! (I too have questions about the fuse)
Booster to LED is almost 4,5A!
I tried several batteries, the more voltage it has, the more current this thing draws.
Tried 2 boosters with same result.
Note that the boosters max input is 10A (manufacturers stats)
Why does this thing draws so much?
Sorry for stupid questions, but Iam by no means an electrician, just an enthusiast.
Thanks for any imput
