My multi-emitter lights which I consider very bright are the Black Shadow Terminator, the Sky Ray King and the TrustFire X-100.
For the price: The cheapest is the SRK, followed by X-100 then the BST.
For the flood: The floodiest is the X-100, followed by the SRK then the BST.
For the throw: The farthest throwing is the BST, followed by the X-100 then the SRK.

I hope this helps.
