Questions about some different flashlights

Hi everybody,

Im new here, and have some questions about some flashlights.

1 Does the fenixE01

Fenix E21

FenixTk75

And a 90 lumen simple cheap 99 meters beamdistance flashlight……Illuminate objects/things at,

40 meters?
100 meters?
600 meters? Or can they illuminate things at 800 meters distance?

And so yes, how bright will the illumination, at 40, 100, 600, and at 800 meters be like, with the fenix EO1, Fenix E21, Fenix TK75, and a cheap simple 90 lumen flashlight, that has a beamdistance stated at 99 meters?

Can you help me with this questions?

Thank you.

Nobody?

Sorry for saying this, but the thread is sinking away.

Please can somebody answer this questions?

So yes, i will be very pleased.

Thanks to you all.

800m none of them.

600m TK75, kind of (about 0.25cd, so yes it's illuminated, but not bright at all)

100m TK75 very well, E21 somehow (with ANSI throw of 145m)

40m TK75 very well, E21 well

E01 has ANSI throw of only 21m, so it will illuminate things quite well up to 10m

I don't know the 90 lumen light, but I would guess that it would illuminate objects at 40m. Not much further anyways..

Hope this helps. :)

Thank you for your reply.

1 What will i see when somebody shines towards me in the dark, at 600 meters distance, with its Fenix TK 75 at turbo/highest mode?

Will i be illuminated a bit?

2 What will be the beamdistance of the Tk75 at

18 lumen low mode? 400 lumen mid mode? 1100 lumen high mode,

and at turbomode?

3 What will be the beamdistance of standard halogen /and the modern powerfull HID/Xenon carheadlights when they are shining straight forward?

4 Can my Fenix TK75 match or overpower todays standard halogen and HID Xenon Carhesdlights at turbomode?

A friend of mine will use its Fenix TK75 as a bicyclelight,

On turbomode he wants,

But which mode is good for bicycling with his TK75?

18 lumens lowmode?

400 lumens mismode?

1100 lumens highmode?

Or is he crazy, that he will getting it on his bicycle with the 2600 lumens turbomode?

Is here somebody ,who will help me with my questions in my last 2 posts above this post of me?

Thank you all very very much.

Im sorry for my lot of questions, but i want know much about flashlights.

Jeebus man… a TK75 for a bicycle light? The thing must weigh ~ 2 lbs with batts, and at that weight, he should consider installing another 1lbs pannier rack to hold it, particularly if on an unsuspended bike. Then, IMHO, the only reason to need that much light and throw on a bicycle would be if your friend can cuise at Tour de France paces (ie, Alps downhill ~ 50+ mph) on 16lbs bicycles… but with ~ 3 lbs of lighting equipment?

A vehicle HID puts out ~3000 lumens from a single light, but is probably more tuned for flood than the throw of the TK.

I personally bike in the country with no street lights, and after my eyes are somewhat dark-adapted, I find ~25 lumens fine for flat (10-15 mph) and uphill sections and ~100 good for rolling downhills (ie, not pedaling in topgear - just gravity topping you out around 25-30mph). But then again, I’m a low lumen fan that hates charging and changing batts all the time.

It’s all about the beam pattern with bike lights! Off road you can ignore that a bit more but on the road you’ll be killed running a TK75 on turbo. I personally use two budget MagicShine clones, with two battery packs, two chargers and a dedicated wide angle lens I’m in it for way less than half a TK75 without batteries or charger (less than £50 all up).

As for the lumen comments, I ride pitch black trails and parks. What 100m of throw gives you is time to react and plan your line. Even at 15mph I find low output annoying but then I don’t have good night vision.

Hi again everyone,

1 When can you call a flashlight a real SAR ,Search And Rescue Light?

2 How much beamdistance do you need, for a SAR light, that search and rescuepersonnel really want and need?

3 Do SAR personnel want my 90 lumen simple aluminium flashlight, that has a beamdistance of 60 meters?

4 And Do they want my Fenix TK75? Is that usefull for them?

1. I don’t know, but it has to be tough for sure.

- waterproof

- shock resistant

- reliable

- easy user interface, so most likely a single mode

  • save powersource because several people will use it without any further instructions

2. Depends on the situation the SAR personal is working in, on the water, in the mountains, in the woods in urban areas ?

3. I say NO, please read #1 again.

4. Could be useful in some situations.
The question is, will the fenix still work when it’s dropped on concrete or against hard materials like walls?
Is it to heavy?
I think SAR people arrive by car or other vehicles, so they can transport a ton of usefull stuff, but they’ll grab the stuff they need and walk towards a designated point.
Remember they might carry things like first aid kit, shovels and a rope if they needs these items in a situation, plus the usual heavy duty clothing like boots and jackets, so the TK75 might be a little bit too heavy.

Notice I got no idea about SAR work, this points above are written using my common sense, this works in most cases. :slight_smile:
