I want to have a thrower. So I thought the Maglite doesn't cost to much and there are many possibilities to upgrade the D-Cell version of the Maglite it should be good as a thrower.
So a really important question:
What is brighter and better as a thrower for the Maglite 2D, LED or incandescents bulbs?

The fact of the matter is, incans are still better for high output than LEDs. So if you want a ton of light, you're probably going to want an incan mod, unless you want to put multiple emitters in.
If you just want a small hotspot that goes a loooong way, an optic is very good, and you can use a lesser emitter. If you want a lot of light and a fairly substantial amount of throw, go for something like a ROP mod with a smooth or LOP reflector.
gunnars thread is very good for summarized all this info.
.....my take on the situation
edit: oh, and even if you mod your light, if you keep the cammed reflector you can still focus in or out.
