The circuit can be made so that three boards turn on and the other the remaining four, if you want I can do it; I never saw serial wiring in this type of lamps, since what you say happens, one burns and all goes out,
If the line is 110 volts you must make the connections for the 110 volt lamps, if it is 220 v, for that voltage.
Imagine that you have 110 volts in the line (that is if you are from Venezuela, or Mexico), then three lamps in series would be 36 volts, and the row of four lamps should be 27 volts, you see that such a thing is not possible.
