I am a complete novice at electronics but like to fiddle. Any way to make this 220V bulb work on 120V or can I just use the LED Panel by itself with a DC power somehow by cutting the wires to the board and adding a resistor. It has 145 LED bulbs. a series of 73 and 72 in in parallel Pics attached thanks. I tried to put the values but frankly I don't know for sure their right . I wish I could swap out a couple things to make it 110v or just add a resister or something to make it DC battery powered. Thanks for any help.

Hello,

I got this in an email from the OP:

I'm not even allowed to ask the part about powering it with DC. Which is the part i am most interested in.

When I look at the led arrangement in the "broken" AC lamp, I see that ALL leds are mounted in series.
To use that on DC you probably need more than 200 Volts DC to let it light up.

You will need to "break" it up into several strings of a couple of leds.

If you want to make a DC battery powered LED lamp take a look at Bill_Marsdens thread on leds:
