LED lights x 3 with RCU

As posted I want to modify one of the lights to power LED string or rice lights and if it works out I can offer this as a lighting option with remote control for the night lights.

As posted this is what I got from the market for $10.



















Pulled one light apart, unsoldered the battery wires and held up to the desk lamp to get some idea of the PCB component and track layout. Interesting that the five LED's are in parallel with the IC switching the negative through the usual current limiting resistor. Cut the track on the LED side of that resistor and connected a length of six string LED's

Lights off..



Turn on lights with remote control.

The question now is how much current can I pull from that IC which has no identification on the package. Enough for now I'll take some more measurements tomorrow and see how it pans out. I need to get that lab power supply.
