He is the one who is going to be wiring the LED's that im ordering and seems to think that the voltage determines the color and such.... sooo this is what he emailed me. Any input is appreciated.

1. Does the voltage determine the color of the LED (ie; 12 volt warm , 24 volt cool white) ??
2. Is there a wiring diagram that comes with the lights?
3. At 12 volts is it still 50 watt, or is that max wattage at 24 volts?

im not an electircian, so im not entirely sure what he is asking.

2. Is there a wiring diagram that comes with the lights? Mine didn't but there's only two wires pretty easy to figure out
3. At 12 volts is it still 50 watt, or is that max wattage at 24 volts? At 12 volts its still 50 watts

1. No. That is determined by the color temp of the LED chip.
2. No. You wire them in parallel so they all get the same voltage. Depending on where you order they can help.
3. the 50 watt lights require 50 watts to run. At 12 Vdc it will pull approx 4 amp of current from your battery. At 24v dc each will pull approx 2 amp of current. P=IV


The LED driver controls the voltage range for the input energy. A lot of the lights can run between something like 9 and 30 volts input, as long a the source can provide enough current at that voltage. If you run them on a 12 system, they will start to dim when the voltage drops below about 12v because the batteries will be spent and won't supply enough current either. If you run them on a 24v system, same thing.

The main difference is at 24 v only half the current is used, so the wiring going from battery to lights can be a lighter gauge for the same losses.

EDIT: there are some reports of people getting longer run times with two batteries in a 24V system versus the same batteries used for 12V system. If this is the case it could be the case that the batteries can be run down further on a 24 v system (harder on the battery life) or it could be that the drivers are more efficient at 24 v.

The color temp is the warm white (3000k) or cool white (6500k) indicator.

Basically what glassbow said but I am going to expand. The LED chips that are used are tuned to a specific color. They actually run from 30-34V. Now the Driver that is referred to is actually a DC to DC boost, constant voltage power supply. These drivers can accept usually between 12 and 30V. they then output a constant voltage specific to the chip that is being used.

you may get slightly better run time at 24V due to driver efficiency, but it will be negligible.
