I added a 10 ohm 25W resistor to the filament string. The filament string is for 115vac and my wall outlets provide 124vac. I thought that the 124vac would be a bit too much for the filament string, hence the resistor. The filament string is now at 117vac using my wall outlet. I used such a big resistor because I had one on hand and also I like to way oversize these things.
