Do you want something pocketable? Handheld? Fit into a back pack?
Incandescent? L.E.D.? H.I.D.?
How long is too long?
How much weight is too heavy?
Do you need it to be waterproof?
What applications will you use it for? (photography, camping, fishing, hiking, indoors?).
How far do you want it to throw? 200, 300, 400+ meters?
How big of an area do you want to illuminate?
You're simply not going to find one universal light that is everything you want it to be, thats why's theres so many flashlights out there.
Sounds like you might like an HID light. A 24W or 35W HID handheld flashlight is about the size of a 2D and 4D Maglite respectively. They are usually very bright (1,500 to 4,000 lumens), rechargeable, and last roughly an hour or so. The downside to an HID is that the bulb is somewhat sensitive and shouldn't be handled too roughly. Some HID lights need 5-20 seconds to reach full brightness, sort of a warm up time. Not all are completely waterproof or "dunkable" either.
Then there are larger HID lights that are bulky and heavy, imagine something the size of a small car battery (not necessarily the weight) with a top handle on it. However, these are considerably brighter and with awesome throw.
The DEFT flashlight can really throw a beam
very far, but its a tight beam and will only illuminate a small area in the distance. See link below for DEFT

Another, less expensive option (with less throw obviously) is the Tiablo A9
with the aspherical head. This a fairly small light and will throw well, but will only really light up a 3 meter by 3 meter area at 200 meters. Same concept as the DEFT.
I'll post a link to a cpf post with some comparitive beamshots outdoors with a good amount of flashlights. Most of the lights are LED but there are some incans and HID's on there. Be advised, the links are VERY pic heavy and require a good computer and modem speed for loading.

BTW, in my experience with some of these high quality flashlights, you can always sell a light that you purchase but don't really care for or use much. Usually you can get around what you paid for, sometimes maybe even more. You can always sell what you buy and don't like on the cpf marketplace.
Good luck!
