Yes, a 5-light Pro6 system is the ideal setup on a RZR. The G6 lights on the Pro6 draw 20W a piece, so the total only comes out to be 100W. Essentially, it's about half the wattage of a comparable ~30" light bar and almost double the output. Final specs will be out in March.
The Pro6 is going to retail for under the $1000 mark for a full RZR system with all necessary hardware and wiring. Keep an eye out for more information soon...
Here are some more pics of it..
