So, I have a 3-DCell Maglight and a...1 AA? Maglight, both incandecent and have always been pretty impressed with them, until I discovered good LED lights. I'm planning on putting a simple $15 LED module in my 3D, just to make it brighter and give me better battery life for emergencies (we have earthquakes here...and darkness in the winter). My 3 1/2 year old has taken over the AA and I don't want to blind him, so I'll leave it be.
When I stumbled onto this weird world of hi-end flashlights, I picked up the Fenix I mentioned above. It's smaller than my mini-mag and crazy (blindingly) bright. Much brighter and clearer than my 3-D Maglight and has a strobe function, should I ever need to disorient an attacker or open a fun house on a budget. I've gotten in the habit of carrying it most of the time at night and it's amazing how often I use it. They're about $65, but somehow I picked one up for $30.
The Surefire thing is such a cult that I found an old 6P on eBay that had some problems and picked it up cheap. I've just about got all the problems worked out of it and it's been fun learning to understand how they work.
I registered on candlepower forums and taking lessons learned from here, did plenty of searching and reading before posting any questions. Very nice people and good responses. Someone asked for my address and mailed me a part without wanting anything in return. They also advised me to call Surefire with my problems. I balked, but then did. This is a 15-20 year old flashlight with a non-stock LED unit in it. I called their customer service number and a guy in California answsered on the 2nd ring. i was honest with him about what I had and didn't ask him for anything, but was I on the right path? He gave me some advice on cleaning and then mailed me a new ($42) tailcap under warranty even though he said "I doubt that it's the problem". Wow! American company with on-shore customer service, standing behind their product to extremes! I understand why people are loyal to them. It's working now and I've got so many spare parts that I've almost got a 2nd Surefire. I'll keep my eye on eBay and CPF until the one piece I'm missing shows up. Plan on having an every day carry light, somethign in my bass bag and lights stashed the cars, basement and bedrooms.
Haven't dropped big dough yet, but I can see that there are people who do. Some need to (cops, corrections officiers, people in rural Minnisota, etc), some are just chasing a hobby. Way deeper than I'll go, but it's been a nice diversion.
