LED with an aspherical projector can reach 1million candle power. That would penatrate deeper than a 1,000watt large plasma chamber halide is able to do, unless it also has an aspherical projector.
If you wish to learn about lights, and LEDs in perticular, I recomend this forum.

If you do searches for the word "aspherical", the pics of the throw on these LEDs is insane. Like putting a bright spot on the side of a water tower at 1 mile away insane...
The only downside is that unless you can source them from some sort of used optics wholesaler, you will be paying around $40/lens, as it's considdered a precision ground glass optic, and many have special AR coatings.
