Longer throw without changing the driver !! :) Prototype is done and now it's time for testing.. ( more beam shots)

[scaru]

Ok, so preliminary tests on the wall make lit look like the fresnel lens increases throw...

Before

After

So quite impressive to say the least!

Ok, so let's take it outside.

Before

After

That's pretty conclusive! For anyone who thinks otherwise here a mouseover is. Mouse over for before; mouse off for after.

So ma_sha was definitely right!

[scaru]

And yes, camera settings were not changed.

[ma_sha1]

Thanks for the hard work Scaru :exmark:

What Da F**k ?? :~ You just urinated on your own argument - you haven’t been out with the very torch this post is about, nor have you seen it up close and personal. Maybe you need the full picture before drawing a conclusion???

Watch your language, I don’t expect a person with potty mouth to know what elephant is by looking at pictures after pictures of it’s tail. However, plenty of people does not need to see the said elephant up close & personal to know it’s not a rope. There is no doubt that spot is much brighter on the wall, it’s the conclusion of more throw that’s being questioned. Where is Dr. Jones when we need him?

Get bent fella. You brought up the dam elephant subject. Not me. How do feel now ??? The pictures just posted fairly conclusivley show you jumped the gun on a conclusion, and were +WRONG+

Actually, they show fairly conclusively he was right. You wanna go look at my pictures again...

Cough cough cough!!! It is a much better thrower with out the lens, this could not be clearer.

Because it’s no longer a parallel beam, The OP needs to take it outside & compare the actual throw, i.e. the distance that light can actually reach, actual distance the light can reach vs, before the mod, it’ll be obvious that the throw will be less

I must be on planet Mars. The ‘after’ shots show a tighter beam. Less flood more throw. How can ma_sha be right ?

It is tighter, that is correct. But the amount of light down range is less. It isn't as bright=less lux.

[scaru]

Ok, here one is with it cropped so it is just the hotspot. Mouse over for before, mouse off for after.

So which one is better lit up?

First time poster here. I just had to join up after seeing this. This is a great thread guys! I’m sure glad I found this place. It’s really interesting!

Okay. So I’m looking at Daylighters’ beamshots. There is no way the ‘before’ shot will out-throw the ‘after’ shot - surely. Even in the alley way it looks like it would easily.

Look at my shots, these were taken on full manual mounted on a tripod. I know these are accurate.

[NightCrawl]

Even the hotspot is not brighter.. also, I clearly see a donut hole.

The pics of DayLighter are misleading, different exposure and aperture (hope thats the right vocabular)..

And, NZ Shooter, please watch your language. I noticed that quite often recently.

[DayLighter]

scaru… are you using the same light as i have?.. there’s no way that trustfire WF 502b have a hotspot like that.
unless it was shot within 10” away
try shooting it farther… like my distance around 80’
by then you’ll see Trustfire wf 502b will no longer have hotspot anymore.
all of you that think otherwise… judge it by yourself… take a simple test,get a magnifying glass and point the light to the middle of it… depending the size of the flashlight… hold it between 8” to 13” and see it for yourself.
and feel free to take it outside and see for yourself… please note this mod won’t work well with multiple LEDs
then come back over here on this thread and let’s compare shots
i’m pretty sure it can throw farther than that 80’ distance

[DayLighter]

same point and shoot camera… just resize it to upload it better…take the challenge for yourself before you accuse someone of misleading

It's a TK35 clone, but the concept is the same. I did exactly as you suggested and got some quite clear cut results. I'll add these were taken at approximately 50 feet.

@DayLighter

Daylight, a point and shoot does not have the same exposure settings each time. It has a computer chip that decides how to set the exposures. On my camera I set the exposures to the same standard Brad, trooplewis, and Rick use and both shots were from the same exact position.

And I have taken the challenge myself, now that I have done it and got conclusive results it is proven. One can easily disprove a theory (like I did) but it is extremely hard to prove it.

[citamul1]

Wouldn’t it settle this once and for all if these shots were taken from a lot further than 80 feet since both versions can reach that distance easily?

I think if this were taken at 300 yards instead of only 80 feet and then measured with a camera that should clearly show which way throws further.

[scaru]

No matter what this light won't throw 300 yards, my STL-V2 couldn't do that. If you guys would like I will get out and take some at 100 yards tomorrow night. (Its 1 am here)

I dont accuse, I state a fact.

A proven fact.

[citamul1]

I just threw out 300 yards. But 100 yards come to think of it makes a lot more sense. I can’t wait to see the results!

@NZ Shooter

Get bent fella.

You brought up the dam elephant subject. Not me.

How do feel now ???

The pictures just posted fairly conclusivley show you jumped the gun on a conclusion, and were WRONG

What’s making this thread so confusing, not blaming you for it, is that the OP has two sets of experiments.

Set 1. Long EFL magnifier lens or fresnel lens to project spot to the wall near focal point,
that’s where my elephant story for, it does not increase flashlight throw.

Set 2. Sticking a telescope in front of a flashlight. This is a totally different optical system.
I am guessing that’s probably what the OP did in his latest 80 feet beam shot.

Telescope works similar to dual aspheric lens set-up, it’ll increase throw, which is dependent on the largest lens, 6” diameter front lens used by the OP? I never said telescope doesn’t work. I made no comments to telescope as it’s not not a flashlight mod, just fun play…

My elephant story has nothing to do with telescope set-up, it’s strictly for applying magnifier glass & fresnel lens in front of flashlight for a mod. My point was illustrated well by Scaru image, it’ll be even more obvious if he increase the distance further.
