The original C7 1/2 lamp was 7 1/2 watts. The bulb was reduced to 7 watts and called C7. Current C7 candelabra base Christmas lamps have been reduced to 4 or 5 watts. The no longer produced C6 lamp produced 6 watts and the large C9 1/2 outdoor intermediate base lamp produced 9 watts. Current intermediate base lamps are called C9 lamps and produce 7 watts. The older lamps got really hot and were a major fire hazard. I don’t know if the wattage was reduced due to legal requirements or to reduce power consumption.
