Some one was asking about how much current certain bulbs drew. I checked out several different bulbs with a current probe. Within the accuracy of my probe and using a battery with 6.3 volts, here are the results.
C.P = candle power
Current = actual measured current draw
Design = design current per G.E. lamp spec. book.
Bulb = bulb number
Old or new is era or modern manufacture.
C.P. | 21 | 21 |
Current | 2.9 | 2.8 |
Design | 2.69 | 2.69 |
Bulb | Old | 1110 |
C.P. | 3 | |
Current | 1.4 | |
Design | 0.63 | |
Bulb | New | 63 |
C.P. | 21 | |
Current | 3.4 | |
Design | 2.63 | |
Bulb | New | 1129 |
C.P. | 50 | 32 |
Current | 5.7 | 4.2 |
Design | 6.18 | 3.87 |
Bulb | New | 1188 |
C.P. | 32 | 32 |
Current | 5.2 | 4.9 |
Design | 4.66 | 4.49 |
Bulb | Old | 2331 |
C.P. | 50 | 32 |
Current | 8 | 5.1 |
Design | 6.53 | 4.23 |
Bulb | Old | 2530 |
C.P. | 32 | 32 |
Current | 4 | 4.1 |
Design | 3.87 | 3.87 |
Bulb | New | 1000 |
Thanks Tom, I was that someone.
Thanks Tom, now, one may figure out what bulbs are good to use, not to go over the wattage capacity of their charging system, either it be the standard Ford generator or other.
Current is measured in Amps. DC voltage of 6.3 is used to simulate fully charged battery
Using the equation : Volts X Amps = Watts
Ford generators questionably can handle 100 watts, but I'm told it shouldn't exceed 80 watts for generator longevity.
Which brings up a variance to the chart. The battery voltage isn't what is running the lights unless the car is parked and the engine off. Charging circuit voltage is higher when the engine is running. Wouldn't that increase the current draw and thus watts?

Thanks Tom, I should have used my Tek scope and probe to do the same thing. As always your ahead of us amateur folks. :-)
Sorry for typo. Should have been you're rather than your. Brain freeze; waiting for the thaw.:-)
A list I made up a while back.
