mini quiz: can u tell which flashlight is brighter and better (ANIMATED GIF)

QUIZ:

1) are you able to tell from the below GIF which light (#1, #2, #3, #4 or #5, from left) is the brightest in frame 1 (=frame 3, colors inversed; t = 1min), and

2) which light is the brightest in frame 2 (=frame 4, colors inversed; t = 18min)?

3) which light has the best regulation between t=1min...18min?

4) which light will be the brightest after, say, 36min?

(click to enlarge!)

HINT: the lumens output is proportional to the black area in the color-inversed frames!

I'm too busy ordering Gucci handbags from Panpan to wory about this stuff...

Rats, finally sold my 2010 509hp Mustang...now I can buy more lights!

Sold the red one too! Now guess what I drive, doing my penance for 500 hp commuters...

i think of creating a few similar animated gifs for inclusion in my posts (e.g. review threads) as embellishment. instead of saying E09 is brighter than A3 it's possible to demonstrate  lumens differences (qualitatively) with such pix.

it doesnt replace lumens measurements or brightness graphs but they visualize what HKJ and selfbuilt had found out. i am very surprised by one of the lights (NEW IN MY COLLECTION YAY!) .. so my mission is to keep records of its performance and share the results.

people might be getting interested in buying the torch *after* having waded through my results and findings (incl. basic measurements).

1) Not w/out cheating, I took screen caps and did a comparo.

2) That;s kinda hard to say as they don't have the same beam profile but if had to vote, it'd be #5 (which kept best regulation)

3) #5 w/#1 coming in 2nd

4) given regulation, #5

What did I win?  Money Mouth

thanks for your participation :bigsmile:

#5 is deceptive because its head is smaller and the black area is larger than it should be imho. here is the solution of the quiz (and also with comments of real life perception):

1) at t = 0 (frame 3), on the GIF the brightest lights are either #3 or #2. it looks like a tie, more or less. maybe #3 is minimally ahead.

2) at t = 18mins (frame 4), all lights have declined in brightness at different degrees. the brightest light is either #1, #2 or #5. since #5 is misrepresented in the GIF, it's not #5. Counting only the pure black area, then #1 is the brightest. On the GIF counting the whole darkish area, then #2 would be the brightest

3) the best regulation from the very beginning on has #1 because the black area (geometric shape) remains virtually unchanged, undeformed. #2 tries hard to stay very bright (and it is indeed the hottest torch after 18mins!) but we can see that it is not well regulated. #3 has lost much in brightness and ties with #4 as the dimmest lights at this point in time. #5 has, as we know (Klarus MiX6), flat regulation but it does perform a step-down from High1 to High2 after 2.5mins, i.e. it doesnt have flat regulation from the very beginning on. the step-down can clearly be seen in the GIF.

4) the light with higher output from t=18mins on AND flat regulation will be brightest after 36mins. since #2 is bad regulated and consumes too much cell power, #2 will have died after 32mins. At some point in between (00:18...00:32) #2 will have dropped in brightness below #1, on the GIF. #3 is already "dim" since 00:18, and #5 was the dimmest at any time (as was measured by selfbuilt, also in graph). So the brightest light at t=36min will be for sure #1!!

The interesting point is that solution1) is ONLY TRUE in the GIF if the Eneloop cell is 100% freshly charged (e.g. 1.54V). In real life (e.g. white wall hunting, ceiling bounce tests, practical use of the light, ..) #1 is clearly brighter than #2, #3 (and #5) as to perceived brightness. Anyone could tell easily by comparing #1, #2 and #3 at night. So the GIF does a poor job of telling us that #1 is actually the brightest at t=0min and at any other point in time. I am sure that one could prove my sensational finding with precise measurements (neither selfbuilt nor HKJ tested this new version!).

In any general or practical situation (e.g. with an Eneloop cell at 1.40V) OR with precise measurements (selfbuilt didnt test this new version neither did HKJ!) it could be proven that the overall brightest light is #1.

Fantastic result. With #1, I have found a torch (1x Eneloop AAA) which is brighter than the Tank E09 and the iTP A3 XP-G R5 at any time! And this is topped by its runtime:

80mins!! (to 50% brightness)

Now talking figures, #4 is rated roughly at "60lm" (manufacturer's specs), selfbuilt had measured 68lm. #1 is rated roughly at "70lm" (manufacturer's specs), and i would estimate a more accurate number is between 80-85lm since it outshines #3 and #5 (both rated above 85lm at t=0min) and rivals my AA-lights:

To be clear:

#1 is definitely brighter than the Xeno E03 XML NeutralWhite on High-mode running on Eneloops!

It would be easier to compare of you had overlayed a frame number on each frame so we knew which one we were looking at.  On my monitor light #2 destroys the other lights in brightness. The black in the inverted colors (great way to see brightness, BTW) is WAY deeper and richer on #2 and covers more area.  Having no clue which frame is the one taken after 36 minutes I can only stand by my original judgement.

xD

 

here is another sample (i am going to label the frames, no prob) for your entertainment:

(click each to enlarge!)

,

what you can see are 6 frames (and then colors inverted):

Tank E09/iTP A3: lo (eneloop) < lo (10440) < med (eneloop) < med (10440) < hi (eneloop) < hi (10440).

And this makes it easy to see that for example High-mode on Eneloop is brighter than Med-mode on 10440's on both torches. You can make out that the E09 is brighter on Eneloops (High-mode) but on 10440's the A3 is much brighter (High-mode). Very interesting! haha (yawn)

If you zoom in with your Windows default viewer you can actually see the PWM flickering on LO and MED modes of the E09.

Has anyone ever measured the lumens output of the iTP A3 with 10440's at t=0min (High-mode)? It is even brighter than Quark X AA with 14500 in Quark's "High-Mode" (but not Quark's "Max-Mode").

What's the point of this thread? To prove/demonstrate that #1 is the brightest of all (with Eneloops). I will test 10440's at some later point, promised Wink

sorry for the spam. hehe.

here pictures with a diffuser tip (click to enlarge!):

,

I am going to post these pix (and related ones) in the Tank review thread and in other threads of interest where a comparison of brightness is desirable. the iTP serves as great reference torch because it is well-known, popular and of high quality. And it runs on Protected 10440's (maybe you can see this in the animated GIF! Wink ) and only few lights exist which beat the "96 lumens OTF" (at t=0min).

probably my last contribution of this kind (animated GIFs yawn):

( click to enlarge! )

 , ,

In the actual review thread i will also include hoover mouse pictures (extracted from the above GIF series) for 2 or 3 key comparisons. in any case the pictures demonstrate that the non-PWM controlled (but current controlled) Fenix LD01 R4 runs on 10440's just fine.

no poof.

 

haha

NOTE: there is an interesting colorization effect on my Samsung LCD monitor, when i watch the animated GIFs (with the non-inverted colors) from an upper angle to the LCD screen, i.e. not 100% frontally: the seemingly white&bright areas would appear in different shades of blue and pink to my eyes. i was trying to reproduce this colorization effect with image editing software (for 100% frontal viewing) but i ...'ed Big Smile

Inverting colors was the easiest/fastest way to reproduce color shading of some sort.
