Does something like that exist for "relatively" small loads like 55 watt lights? I gotta good reducer, but don't want to hit it with that kind of "inrush". |

Regardless of size, both motors and incandescent light bulbs have current curves somewhat akin to a capacitor's current curve, or at least to the extent that they both draw max amps initially and then taper off over time. The 15:1 hot/cold resistance ratio I mentioned is for a 120VAC incandescent bulbs, but the difference between a 120V and a 12V incandescent bulb is the filament thickness, so the ratio should hold fairly true. However, halogen type incandescent bulbs operate at a higher temperature, so the ratio might be greater. If you are curious, measure the cold resistance of a 12V halogen bulb with and ohmmeter and then measure the Amps and Volts while it is operating and calculate the hot resistance. |
