twist, same as 6P, the clicky switches are ridiculous expensive. lumens is relative because any p60 compatible drop-in can be used(one of if not the biggest reason they remain popular, because when newer, better LED's come out, its just a new drop-in lamp, instead of buying a whole new flashlight). It comes with the stock p60 lamp which is like 65lumen, though you could just order a drop in of whatever the newest bin cree LED is from china for like 10bucks, that'd put you close to 250lumen. On the back it says 60min runtime, which is horrid IMO, but then again thats for an incandesant bulb. You can always order rechargeable li-on batteries and a charger(rcr123's run about 7 bucks each, and a charger will run you about 12), those will also give you a small kick in brightness because of the added voltage.

I mean you can see on the package it says its brighter then a 4D maglite
