If you want twice the "throw", then because of inverse square law for light, you will need 4x as bright as light to an object twice as far away with the same amount of light returned to your eye...
So, if a P3D-CE is around 160 lumens, you will want a light that is 640 lumens or brighter (all things being equal--which they rarely are)...
This would be based on a beam similar to the P3D-CE. Of course, you could have a light with a tighter spot which will throw farther, but at the expense of spill and a smaller spot on closer objects (i.e., a laser has great throw with very low power, but a very small spot and no spill).
Generally lights with better throw have larger diameter heads (for same lumen input).
Comes down to want you want--a cheap 1,000,000+ candle power spot light with internal lead acid battery will be bright and throw well--but with a 25-35 watt bulb, they will not last much more than 15 minutes.
There is a lot done in the incandescent forum with ROP (Roar of the Penguin)--A standard bulb overdriven in, typically, an easily modified MagLight (several body options).
Certainly a very bright and usable light, that you built yourself, to your needs, with off the self parts and/or a few parts from CPF modders/vendors (glass lens, metal reflector, NiMH AA battery holders, etc.)...
I don't think you will find many LED module "drop-ins" that will do what you want yet... There are some limited run multi-Cree lights out there (seem to be a bit pricey right now), if that is more what you are looking for.
Really depends what is interesting to you.
