MikeHem510 there are a few differences here to be told. We all know that the standard for LED light color is being more white in the 6000k range. The C3 will have this color temperature where as the LZR will lean toward the 4500-5000k range. We prefer the warmer temperature as it is easier n the eyes off road and produces less reflection back to the driver. Output is the next difference with the C3 being 12w (4320LM Kit) and the LZR being 20w (10,400LM Kit). Will you be disappointed in the C3, we highly doubt it as they perform well (we do not sugar coat the lumen count) and ultimately for the price you are getting an excellent light at a great value. The LZR is going to cost a bit more, but again the value is their in relation. Below is a link to a great write-up for you to review on the LZR Raptor system. The LZR is only offered in a driving pattern, although it truly has plenty of distance and fill for this position on the truck. The C3 is offered in the spot pattern, although your KC dealer can order with other combinations if you choose. Many have stated they do not mind this spot option because there are (4) lights so you get plenty of width and the stock head lights are really good on the Raptor so they cover the shorter fill. It leaves you with some options to choose based on your needs and budget.
