GE introduced direct current C-7 and C-9 sets a year or so ago.  The C-7 lamps are 2.75 watts each.  Does anyone know what voltage they are?  The bulbs are cone-shaped exactly like the original ceramic C-7s long out of production.  I'd like to put these bulbs in older sets but I am afraid they are lower voltage.  There is zero information about these lamps on the net.

Thanks!

Alex the lamps are about 83.5 volts and they run on diodes, so no they are not interchangeable with traditional Christmas light sets. I have a GE Watt-Miser C-9 string with all clear lamps in use up front right now, and the lamps flicker slightly because they run on half cycle DC. Weird for sure.
