Oscillator Powering 6 Modified Led bulbs

Well, you can use any resistors in series, if you have some say 56 or 82 or 120 Ohm, not critical.

I have a question about using this type of power supply shown below.  The rating is 20 amps. The power supply has TWIN DC terminals.  Does that indicate I can only draw 10 amps off one dc terminal and 10 amps off the other dc terminal??  Or can I draw 20 amps off only one of the terminals?

No answers from the seller so far.

Well if you can see three  COM and three V+ labels above the terminal strip like on this power supply I chose at random:

then it means you can draw 20A from any one COM and one V+, ok?   The three COM terminals next to each other are the same negative polarity and the three V+ terminals are the same positive polarity outputs.  The expalanation for having 3 of them each is to increase connect surface area. No restriction for 10A or whatever.

Thanks for the explanation.  I have one on order and did not want to damage it later on.

Hello Skywatcher,

Will your circuit drive 7w 220V led bulbs or was it specifically designed for 40w led bulbs? Am thinking that having several multiples of 7w 220V led bulbs is better suited to my replication of your circuit.
