draw 0.104 amps
A 65 Watt incandescent light bulb should draw 65W/120V = 541.67mA
The 194 bulb is ~3.8 watts, at 14 volts they draw 0.271 amps.
1/2 amp.
1 amp
draw 0.104 amps
About 0.6 amps for a 12v 21w bulb
It is drawing .06 amps.
A 65 Watt incandescent light bulb should draw 65W/120V = 541.67mA
The question isn't what you're powering with a particular gauge of wire, but what's the current draw. If the metal halide light can run on a 15 Amp breaker (from the breaker panel), fine use your metal halide in your residential application and run it on the 14 gauge wire.

Depends on the size of the LED light and the voltage applied. An example is an LED 24 volt globe light that pulls 8 watts which draw 0.333333 amps. Take an LED 120 volt light bulb draws 12 watts and will pull 0.1 amps. The same bulb at 240 volts wil draw 0.05 amps. it really depends on the watts and voltage applied. An average would be about 0.1 amps.
A 50 watt bulb designed to run on 12 volts takes 4.17 amps. A 50 watt bulb designed to run on 230 volts takes 0.217 amps.
The equation that you are looking for is I = E/R. Amps = Voltage/Resistance in ohms.
Watts = Volts x Amps x Power Factor. An incandescent light bulb is a resistive load so PF = 1. ANSWER: = 1/2 Amp
