I have been reading through the post for the last couple of days and I think I just getting more confused I found the Question sheet on the first day of reading but though it should be easy to find what I need. I know there are 3 other sticky threads that deal with LEO lights but they seem to be for the bigger lights. Thanks

0) What Region/Country/State will the light be purchased in?

_x___I will be mail-ordering or buying online, so this doesn't matter.
____I am in North America. More precisely I am in _______________.
____I am in South America. More precisely I am in _______________.
____I am in Europe. More precisely I am in _______________.
____I am in the Middle East. More precisely I am in _______________.
____I am in Africa. More precisely I am in _______________.
____I am in Asia, Japan or Micronesia. More precisely I am in _______________.
____I am in Australia. More precisely I am in _______________.

1) Price Range: An easy question, but you may change your mind after answering the rest! :-)

____I only want to pay $1-10.
____I can spend $15-30.
____I could spend $40-60.
__x__I am willing to spend $80-$150.
____I have no limit!

2) Format:

__x__I want a flashlight.
____I want a headlamp.
____I want a lantern.
____I want a portable spotlight.

3) Length:

____I don’t care.
____1-2 inches. (Keychain sized)
__x__2-6 inches. (Pocket carry)
____4-9 inches. (Holster carry)

4) Width:

____I don’t care.
__x__I prefer a long narrow light.
____I prefer a short wide light.

5) What batteries do you want to use? Alkaline batteries are easier to find and less expensive but don't pack as much stored energy and are don't work well in cold temperatures. Lithium batteries have long shelf life (10+ years, great for stored emergency lights) and are not as affected by cold but must be kept dry and are more expensive. Rechargeable start expensive, but if used frequently pay off quickly.

____I want common Alkaline batteries. (AA, AAA, C, D)
__x__I want lithium batteries. (coin cells, CR123, AAA, AA...)
__x__I want a rechargeable system. (an investment, but best for everyday use)

6) How much light do you want? Sometimes you can have too much light (trying to read up close up with a 100 lumen light is impossible).

__x__I want to read a map, or find a light switch, in a dark room. (5-10 lumens)
__x__I want to walk around a generally paved area. (15-20 lumens)
__x__I want to walk unpaved trails. (40 lumens)
__x__I want to do Caving or Search & Rescue operations. (60+ lumens)
____I want to light an entire campground or dazzle an intruder. (100+ lumens)

7) Throw vs Flood: Which do you prefer, lights that flood an area with a wide beam, or lights that "throw" with a tightly focused beam? Place an “X” on the line below.

Throw (distance)-------------------x---|----------------------Flood/close-up

8) Runtime: Not over-inflated manufacturer runtime claims (like some LED lights). but usable brightness measured from first activation to 50% with new batteries.

____20 min. (I want the brightest light for brief periods)
____60-240 min. (1-2 hours)
____240-360 min. (4-6 hours)
____360+ min. (More than 6 hours)

9) Durability: Generally the old phrase “you get what you pay for” is very accurate for flashlights.

____Not Important (A “night-stand” light.)
____Slightly Important (Walks around the neighborhood.)
__x__Very Important (Camping, Backpacking, Car Glove-box.)
__x__Critical (Police, Fire, Search & Rescue, Self-defense, Survival.)

8) Switch Type:

____I don't care.
____I want a sliding switch. (Stays on until slid back.)
__x__I want a "clickie” switch. (Stays on until pressed again.)
____I want a momentary switch. (Only stays on while held down.)

9) Switch Location:

____I don't care.
____I want a push or sliding switch on the body near the head.
__x__I want a push switch on the back end of the body.
____I want a rotating head switch.
____I want a rotating end-cap switch.
____I want a remote control.

10) Operational Modes: Check all that apply.

____A simple on-off is fine for me.
____I want 2 light levels. (Brighter/short runtime and Dimmer/long runtime.)
__x__I want multiple light levels. (some lights have 5-16 light levels.)
____I want a strobe mode. (blinks to show location.)
__x__I want a tactical strobe. (Flashes rapidly to disorient an opponent.)

11) Is it important whether the body is metal or plastic/composite?

____I don't care.
__x__I want a metal-bodied light.
____I want a plastic/composite light.

12) Special Needs: Is there anything else you want or need that hasn't been mentioned? Circle any below or write in your own comment(s).

____Red (night vision preserving) filter
____Other filter colors (Amber, Green, Blue, _________)
__x__Waterproof – how deep: _____________
__x__Non-reflective/dark finish (stealthy/hard to find)
____Polished silver or brightly colored finish (for easy locating)
____Corrosion resistant or hard-anodized finish
____“Hybrid” light (bright incandescent combined with long running LEDs)
____Built-in second (or spare) lamp or filament
____Belt/Jacket clip
____Wrist/Neck Lanyard
____Kobuton/self defense features
____Non-sparking Intrinsically Safe (IS) for use in explosive environments

I would like to add a little to this.

13) able to be mounted on rifle it comes with or after market (just a prayer quick release mount) kind of like my M3 I use on my service weapon.
14) remote switch comes with or after market

Ive looked at the M20 & M30 from Olight the Jetbeam and the Fenix but can't seem to see them side buy side in my head. Looking for some help from people that use them day to day. I want to be able to step out of my car walk up to another and shine it inside to see. Then mount it on my long gun go in a house with my K-9 and search. I like the stobe idea because I work in a college town and deal with a lot of drunk kids that need help but not hands on help to get there attention. Plus the long MAG type lights and the leash just are a pain. I probable have forgotten something but it's a start. Thank you again for your input.
