The porcelain Leviton Lampholders were $2.79 each.

I bought 4 more 85 watt 6500 k CFLs ... Total of 8 in parallel.

Doing the simple calculations ... 85 watts x 8 = 680 watts

Current draw is 680 watts / 120 volts = 5.67 amps

CFLs are more complicated than incandescent ... They are said to be "Reactive loads" .....

So a " Power Factor" is used to differentiate between real power (watts) and apparent power (Volt x Amps or VA). They are identical in purely resistive loads ... when current and voltage are in phase ... the power factor is 1.0.

In AC applications ... Watts = VA x PF

CFLs are said to have a Power Factor of 0.5 to 0.9

Worst case scenario .... my 85 watt bulbs may at times, have an apparent power of 170 VA

So, in this worst case scenario ... Current draw is 8 x 170 VA / 120 volts = 11.3 amps

Well below my 20 amp breaker.
