Converting 120VAC to 60VDC: Tips and Tricks for Your LED Light

[jerromyjon]

I have this 6 element LED light I found on the road which when I took it apart to connect a vacuum cleaner cord I googled the number printed on the aluminum (assuming) circuit board for which I found specs saying 60vdc max at 45W. I currently use it as a portable drop light connected to 18vdc battery shown using a rigged-up 120vdc receptacle because it was easy... what I am curious about is what would happen if I plugged it into a 120vac outlet. Would it being diodes cause it to work as 60vdc or is there an easy way to adapt 120 vac to 60 vdc? I'd hate to burn it out by plugging it in and see what happens. Thanks in advance if anyone has any ideas!

It's easy to get 53V dc, if 120V is the RMS (not amplitude) of your AC:

L1 must be "big enough";
if you directly, or via some serial resistor, feed LEDs, then it's probably better without C1 and R1.

Sorry, what you are discussing is dangerous. It's very bad practice to use AC Mains power without isolation. Thread is closed.
