Every drop-in I've purchased included the reflector. Doesn't matter which p60 host you put the dang thing in, you get exactly the same beam. Every time. AN expensive host is a joy to hold and behold, but my $85 Pelican host throws the exact same beam as my $8 Ultrafire host when I swap the drop-ins between the two. LOL, someone mentioned the bezel of the host may change the beam. That is true, it will 'scallop' the edges if it has a crenalated bezel, but the beam is actually the same, your host just cut part of it off.
14) Be aware that claims of 1000-1400 lumens from single cell 18650 flashlights are bogus! Ebay and many Chinese web sites claim these numbers, but they are almost always off by a factor of 40-50%. The very best lights, like a TK41, can manage 800+ lumens with EIGHT AA batteries, and that thing is a hundred bucks. You are not going to get 1000 lumens out of your $25 Ebay light, but that does not mean it won't be the brightest light you ever bought. Prepared to be amazed, but not 1000 lumens worth of amazed. Remember, in comparison, your Dad's 2 x "D" cell Maglite put out about 29 lumens.
15) Many inexpensive torches have PWM. PWM stand for Pulse-width modulation, it is basically a cheap way to obtain Medium and Low modes. It isn't necessarily a bad thing, unless the PWM is very slow, in which case your eyes may detect it as "flicker" or a fast strobe. Members here detect PWM by holding a flashlight in a dark bathroom, and then waving their arms around with it in the shower. Get used to the idea, flashaholics are strange people.
