I have an old 2D maglite and I want to make it into a nice light. I've looked at the ROP build and studied it a good bit but i'm just not sure that it is for me . The thought of having to replace burned out bulbs and the fact that I can't run down to the store to get them I have to order them turns me off of the whole ROP mod. I don't think I want to go incan, I think I want to do a LED build. I've seen a couple of posts about people putting p7's and p4's in mags, but I don't know how bright they are. Really I need a good run down on LED's, how much they cost, what bin I want, where to get them, how bright they are, and how many volts they need to be good. I have a couple of instant messaging handles I would love to talk to someone who is knowledgable in LEDs and can steer me in the right direction.
