I believe the machining process is what makes Surefire more expensive. I've found that my Surefire X300 (110 lumens) was just as bright as the TLR-1 C2 (135 lumens) and my LX2 (200 lumens) just as bright as the TK-11 R2 (240 lumens). I love Surefires and prefer them over any other light but you have to be willing to spend the cash. I know I can trust them so I have no problem doing it.
The TLR-1 will suit you fine if you don't want to spend all that cash on a Surefire.
