Re: Newbie Q
There is no ranking list. It's largely subjective and CPFers will argue until they're blue in the face over which manufacturer they think is best.
I don't think that's quite true if "price is no object"
Here's my poll results (via the "information subjectively absorbed" polling method) from a few months on CPF. Obviously, there's popular brands that are missing from my lists, but you get the idea.
Durability rankings
1) HDS (Ra), Malkoff, SureFire, Streamlight
2) Maglite (besides bulb issues), Fenix TK series
3) EagleTac (barely above 4, and my personal experience isn't that good)
4) Quark, the rest of Fenix stuff, more expensive iTP stuff, O-light, Zebralight, etc (think $50-$100 stuff)
5) Romisen, cheaper iTP
6) DX/KD/Ebay no names
Efficiency/feature/value rankings
1) Quark, Fenix, EagleTac, Zebralight
2) Everyone else
3) Surefire, Coast
Regardless of my poll numbers, if you spend a fair chunk of change in whatever genre you are interested in, you'll get a damn fine light.
$50 for an EDC single cell light
$100 for a hand filling utility light
$150 for a high powered thrower
$300 for heart of the sun spotlight.
As mentioned above, budget and personal preference will dictate your choices, because there are just so many damn good lights available now.
