1) How would you prefer to purchase the light?

____I would like to purchase the light in person from a brick and mortar store. I am located in ______________.
_X__This will be mail-order or Online (location doesn't matter).


2) Budget: An easy question, but you may change your mind after answering the rest! :)

__x_I don't know yet
____Up to $25.
____Up to $50.
____Up to $100.
____Up to $200.
____Up to $300.
____Essentially unlimited.

____I am not sure, please help me decide.
__x_I want a flashlight (hand held/self contained).
____I want a self-contained headlamp.
____I want a headlamp with an external pack/power source.
____I want a mounted light (typically for a bicycle or vehicle)
____I want a lantern/area light.
____I want a portable spotlight (it may have an external power source).
____Other ____________________________________________


4) Size:

__x_MICRO - Keychain size.
__x_TINY - Every day carry (2-4 inches).
____SMALL - Every day carry (4-7 inches).
____MEDIUM - Holster/belt ring carry. (>7 inches)
____LARGE - Big enough to need its own travel case.
____I don't know/I don't care.


5) Emitter/Light source:

__x_LED (known for efficiency, longevity, and compactness)
__x_Incandescent (known for superior color rendition)
____HID (known for max output, but often at the expense of size)
____I don't know.


6) Manufacturer:

____I want to buy a light from a large/traditional manufacturer that is ready to go out of the box.
____I would like a light from a specialty manufacturer (Possibly limited run/Custom).
____I am interested in assembling my own components. (for example a "host" or flashlight body from one manufacturer, and a "drop-in" emitter from another source).


7) What power source do you want to use?

____I intend to use "Primary"/Disposable Alkaline batteries based on the usual AAA/AA/C/D sized cells common to most stores.
_x__I intend to use "Primary"/Disposable Lithium batteries based on the usual AAA/AA/C/D and CR123 sized cells common to most stores (often a cold weather or long storage choice).
____I intend to use Rechargeable cells (NiMH or NiCD) based on the usual AAA/AA/C/D sized cells common to most stores.
____I intend to use Rechargeable cells based on less common formats (18500 or 18650 Li-Ion, RCR123, et-al).
____I want a light with an integrated rechargeable battery pack.
____I don't know/I need more information on power sources.

7a) If you have selected a rechargeable option
____I want a light that plugs directly into the wall (literally with prongs built into the light)
____I want a light that has a recharging adapter (your typical "wall wart")
____I want a light that snaps into a cradle (usually mounted on a wall)
____I want a separate/stand-alone charger (this involves removing the batteries to charge)
____I don't care


8) How much genuine out the front (OTF) light do you want/need? Sometimes you can have too much light (trying to read up close up with a 100 lumen light is not a happy experience).

__x_I want to navigate a dark room or read a map (1-10 lumens).
__x_I want an indoor "blackout" light (15-50 lumens)
__x_I want to confidently walk around an unlit/unpaved rural area (60-150 lumens).
____I want to illuminate my entire backyard or a campsite (150-300 lumens).
____I want to illuminate an entire field, the neighbor's front yard several houses down, impress my friends and neighbors, etc. (300-700 lumens).
____I want search and rescue type illumination (800+ lumens).

__x_SPECIAL NOTE: Burst/Turbo mode Category - There are several lights that will run at a super bright maximum for a very limited period (usually 5-10 minutes) and then will "step-down" to a lower level for thermal control. Check here if this is acceptable.


9) Flood vs Throw: Flood covers an area, Throw reaches out to a distance.

____All Flood: I am doing "arms length" tasks like reading and campsite cooking.
____Wide Flood: I want a defined flood area for semi-close tasks like after-dark campsite tasks or working on a car.
____Narrow Flood: I want a sharply defined flood area that will project some distance for tasks like trail walking.
____Wide Throw: I want a beam with a noticeable hot-center for distance throw and a significant amount of "side-spill". Good for rough trail hiking, search and rescue, and general distance work.
____Narrow Throw: I want a beam with a very tight "hot center" and minimal "side-spill". Good for distance viewing, fog, and looking through dense undergrowth.
____Turbohead: I want a far-distance projector with a sharply focused spot of light and minimal or zero side-spill. Good for extreme distance and impressing your friends.

9a) Distance: How far away will you typically need to see with this light (check all that apply)
__x_Less than 1 yard/meter (reading, other close work)
__x_Less than 5 yards/meters (looking for something inside a dark shed/garage/basement)
__x_5-20 yards/meters (check out a noise in the backyard)
____30-50 yards/meters (I have a big backyard)
____50-150 yards/meters (I live in a very rural area/farm with wide open spaces)
____150+ yards (I am searching from a helicopter)

10) Runtime: Not over-inflated manufacturer runtime claims, but usable brightness measured from first activation to 50% with new batteries (Measured on maximum continuous output).

____Up to 30 minutes (I want the brightest [and potentially smallest] light for brief periods)
____30-60 minutes (I have plenty of batteries just ready to be changed)
____90-120 minutes (Runtime is moderately important, but still not critical)
_x__3 hours + (I critically need this light to run on max for extended periods in between battery changes/charges).




11) Durability/Usage: 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).
____Critical (Police, Fire, Search & Rescue, Caving, Survival).
____I don't know.


12) Switch Size, Type, and location (choose all that apply):

_x__Any size switch will do.
____I need a BIG switch (I'll be using gloves or have very large hands or coordination issues).
____I want a forward clicky (Helpful for momentary activation and signaling).
____I want a reverse clicky (For use with multi-mode/level lights).
____I want a momentary switch (Predominantly for use with signaling and short bursts of momentary light only).
____I want a twisty switch (Tighten the head/tailcap to activate, and the light will stay on until the head/tailcap is loosened).
____I want a body mounted switch (near the head, like on a Maglite).
____I want a tail mounted switch (found on the majority of today's high end lights).
____I want a remote switch (usually found on high-end bicycle headlights)
____I don't care.
____I don't know.
____Other, please specify____________________.


13) User Interface (UI) and mode selection. Select all that apply.

__x_A simple on-off with only one output level is fine for me.
__x_I want 2 light levels. (Brighter/short runtime and Dimmer/long runtime.)
____I want multiple light levels. (Some lights have 5-16 light levels.)
____I want a programmable light.
____I want a selector ring.
____I want a strobe mode. (Oscillating pattern to confuse/blind aka "Police Mode")
____I want SOS mode. (blinks in ...---... emergency pattern)
____I want a beacon mode. (Regular flashes at full power to show location.)
____I don't care.
____I don't know.


14)Material/Finish/Coating

____Plastic/composite body (this may limit your choices significantly).
____Anodized Aluminum – either type II or III (Hard Anodized) (Aluminum, specifically HA, is the most common material/finish for today's higher end flashlights).
____Stainless steel (durable, but much heavier than aluminum)
____Titanium (durable and nearly as lightweight as aluminum, but can be moderately to significantly more expensive).
_x__I don't care.
____I don't know.
____Other, please specify____________.

15) Water resistance

____Non-sparking, Intrinsically Safe (IS) for use in explosive environments


Hey guys,

Long time since I've come to this website or thought about flashlights. My roommate in college was a big flashaholic and introduced me to the hobby, I remember being amazed at the original Sundrop; I didn't know that a LED light could have such a beautiful, warm tint. It has been a few years since I've had an EDC and I'm hoping for some advice. My previous lights were an old Arc-AAA as well as a SS LD01. I'm ideally looking for something I could keep on a keychain though a small penlight style would work fine as well. Useful for basic tasks or walks. The last utility I was hoping to get was to find a light to use for pupil/throat exams (perhaps advice as to some sort of diffuser so I don't blind people or a light with variable output?). Don't think there will be anything out there that might check all these boxes but figured it was worth a shot. Something I've looked into is the Sapphire GS but wanted to know if there was anything you would recommend. Thanks for the help in advance!

I gave my daughter a Nitecore MT06MD a few months ago. She's a pediatrician and uses the light for throat exams but not sure about pupil check. (I'll have to ask her on that one). One criteria you should demand is that the LED has a high color rendering index (CRI). These show skin color realistically. Cool white emitters are terrible at this. I would also suggest that the light always turns on in low. The MT06MD checks these boxes-High CRI (93) Nichia emitter and always comes on in low. It runs on two commonly available AAA batteries. Hope this helps!

Maratac has a 1xAAA that I like pretty well, Nichia high CRI, twisty interface (med, low, high). For more runtime, there are a lot of 2xAA medical lights. Go for a high CRI one like the nitecore mt06md, which I think you can get with a pupil gauge. For a more pocket friendly option with more runtime than a 1xAAA, a big step up in quality and price is the Zebralight SC 53c.

I agree on the MT06MD. It is available in plain black anodizing, or with a pupil size chart along the shaft for reference. Also, and I just found this out when investigating the MT06MD when it came out, it is certified safe for blue light. We all know that UV will harm one's eyes with enough exposure. And we know that right past visible blue in the spectrum is ultraviolet. Apparently, a lot of lights, especially in the cool white/daylight tint will also produce enough UV to damage an eye being examined. Since this is so, there is a certification that can be obtained to certify that the light in question only produces safe amounts of UV, and the MT06MD is so certified.

Doctors, nurses and EMTs will find the MT06MD ideal for pupil examination and injury diagnosis thanks to the diffused beam and high CRI rating (>90) of the Nichia 219B. Not only will this penlight reveal color more accurately, but the output has an RG0 rating to eliminate blue-light hazards. The MT06MD isn't only for medical professionals, either. Operating on 2 easily sourced AAA batteries and offering a run time of up to 35 hours, the MT06MD works great for household chores - especially work in close quarters where a flood of light is essential.

If 180 lumens and a throw of 60 yds doesn't meet your other needs, then I would suggest the Nitecore EA11. It is a single 14500/AA cell light. Using an AA cell (alkaline, lithium primary, or NiMH) it won't be any brighter than the MT06MD, but with a 14500 Li-Ion cell it will do 900 lumens with a throw of 200 yds.

If the MT06 had been available back in the day when I was wearing a suit to work I would have been more than happy to have it as my EDC. It is that classy. And the EA11 is my goto EDC when my Microstream just doesn't cut it. Small enough to get lost in a jeans pocket or ride comfortably in its holster on a belt, and with a 1 lumen moonlight mode, it is just right as an all around EDC.

I forgot to add - if you really want a key chain light, the 2017 Tip CRI would be a great solution. Available in many different colors including Stainless Steel, it fits the bill as an unobtrusive yet powerful light. Many of us have purchased the accessory clip that covers and protects the USB charging port and adds a pocket clip to the light. DO NOT purchase an original Tip - one that doesn't have the 2017 identifier. The original Tips had an unreasonable parasitic drain that would rapidly completely discharge the light.
