KC HiLites

So i have a pair of the 100w halogen Apollo series driving lights and they work really well, i wouldn't trade them for anything (other than LED's). I was just wondering if anyone has ever put the 130w halogen bulbs in them and can it work like that. Im more worried if they will fit or not. the part numbers only seem to be one off from each other so im guessing it can work. Let me know if anyone has done this to their jeep.

It depends on what the reflector is made of and the wire gauge of the electrical supply wire. A 100 watt bulb demands 8.33 amps of power @ 12vdc. A 130 watt bulb will demand 10.83 amps @ 12vdc.

If the reflector is plastic/polymer, I would check with the factory before doing it because more power creates more heat. If the reflector is metal, then you should be safe. Keep in mind that the 130 watt bulb is going to be drawing slightly more than 30% more amperage and that requires larger gauge wiring to support it.

do you know if all of the gauging for the kc apollo series are the same or not?

The last time I bought a KC product was in 1979, so I don't know what they're using or the quality. Give them a call and see what they say.

If you are going to run a supply line to a 10.83 amp load, you will need a wire gauge that can safely carry the peak load.

Using a quality 12 gauge stranded copper wire, your maximum length of run is 14.4 feet and with a 2% loss, your terminal voltage will be 13.61 volts. This is the absolute minimum size wire. If you plan to use the lights in a hot climate or for extended periods of time, go to 10 or 8 gauge.

Using a quality 10 gauge stranded copper wire, your maximum length of run is 23.0 feet and with a 2% loss, your terminal voltage will be 13.7 volts.

Using a quality 8 gauge stranded copper wire, your maximum length of run is 36.6 feet and with a 2% loss, your terminal voltage will be 13.71 volts.

thanks. im ganna have to call and see what guaging the wires are. i will definetely look that up. what equations are you using to solve for the terminal voltage
