A set of the 6" HID KCs has 600,000 candlepwer at a cost of $850, but the slimline 6" KCs have 300,000 candlepower at $175. Soooooo at that rate you could pick up almost 5 sets of slim light (4.86 sets), that would be 10 slimlights putting out 3,000,000 candel power. Other than the pure redicoulousness of running 10 lights, does that math work out? I dont know how to compare candlepower. Would 2 sets of Slimlights be close to the actual light output of one set of HIDs? it would be 600,000 candlepower to 600,000 candlepower, and a savings of $500 over the HIDs. I know the amp draw is way different, just wondering about the actual light output.
