high cri led lamp

(1/1)

daniel444:
just posting my lamp design
uses a bridgelux 93cri  3500k cob led
Chinese boost driver 52v max
unprotected 18650 batteries in series
physical switch 16Amp , no parasitic drain
voltmeter to monitor battery voltage  , the protected batteries dont fit in these smd battery holders , and i dont like buying them so the voltage needs to be monitored
3mm x 50mm aluminum flat bar
it runs 5 to 10watts
bent the aluminum  with a blowtorch otherwise it is not a smooth bend, it requires clamping in a holder , can be bent by hand without blowtorch
hardwood base

i wish they made a boost driver that has built in dimming potentiometer , and a selectable battery cut off voltage
