Help with Offroad lights

[RodsRVF]

I want to buy some offroad lights but I need some help. Will I notice a difference between a 6" and 8" light? KC makes a 6" in 150w and their 8" is 130w, why would they not make the 8" in 150w too?
Thanks for the help.

you could call KC and ask them.. as they designed them and should know..

I believe the bigger the lights the less Watts you need as it will produce a broader beam...

The bulbs are probably interchangeable.

KC's 150 watt bulb is a sealed beam, aircraft landing light style of bulb. The 130 watt lights use halogen lamps inside. 8-inch lights are freakin' huge...
