well… the idea of my creation was based on that telescope. i was merely trying to build it bigger so i can accomodate more flashlights.
the built was not perfect, its the idea what i’m selling,hence the prototype… some people just didn’t pay attention to that.
they’re hoping to see well built finished product that can throw monster output.
common sense will tell you… you can’t really turn any flashlight that worth less than $15 into HIDs like thrower.
However… it can turn those cheap flood lights into throwers or at least throw farther than it normally could.
and i’ll stand by that statement.
simply get a magnifying glass and test it yourself… i’m using 2X magnifying glass that i bought from dollar store.
Actually, I am going to change it up. I will go take beamshots at the same location I did for my 300 yard shots. I will be using a 8.5*11 inch fresnel lense along with a Stanley Fatmax XM-L. I am doing it this way so we can have long range shots, which this light is capable of stock; and it will clearly demonstrate that there is less throw.
Adding a concave optic before it is not part of the expirement, as that is not what I am saying will not work. I acknowledge that will work, but a simple fresnel lense will not increase throw. I am positive of that.
Of course I have been there and done that. The problem is, if you want the beam to stay focused you constantly have to adjust the focal length depending on the distance of the target you want to illuminate. And that's not very convenient.
not trying to beat a dead horse here, sorry. But I think what Daylighter is saying, is that you have to use a flashlight that stock DOESNT throw far. Using a light that you says already throws far is pointless and not what what put forth in the OP. If its a stick light that DOESNT throw far already, and you use the Lens, hes saying it will increase the throw. What youre proposing will not be sufficient to prove anything in this regard.
So instead of using a torch that has throw, use one thats all flood no throw. THEN perform your test with the lens and take beamshots. Either way, I apreciate you taking the time to test this theory, i know taking beamshots is somewhat difficult and time consuming.
i still stand by my statement, question is… how far of a throw are you expecting? all i’m saying is… all the light that i’m testing is capable throwing farther than the light itself capable of.
if you’re expecting that Trustfire WF 502B will defeat TN31 or HIDs kind of beam… you’re in for dissapointment…
but if you compare that 502b with something decent like C8… i’ll stand on my statement it can certaintly beat it.
like i said… this is a prototype, not a perfect built… i’m selling* my idea *not my built.
my idea is based on using the telescope kind of device to throw the light more forward. but you guys acted as this is already the final build.
like i said it before and i’ll say it again untill somebody understand this… this is an IDEA that i’m selling, as the prototype will work or not to your liking is another story.
i’m just hoping someone will take this idea and step up and make it a better one, let’s end this for argument sake … it simply works!
if the final shot of over 300’ using a cheap Trustfire Wf 502B can’t convince you… then i have nothing else to say :~
A telescope will certainly work, we never said it wouldn't... Using one lens will not. But ok, I will take some using my triple XM-L drop in. Which is all flood.
either you don’t get it or you refused to accept or you maybe have set the limit too high on this experiment.
like i have said before… using light which have bigger output than that i’m using, beat the purpose of this experiment…
maybe you’re expecting monster throw like HIDs hotspot to satisfy your finding… instead doing a simple light test using the cheapest kind of light to see if my idea works or not.
as far as anybody else want to take up the challenge… i’m still standing on my statement, that using this mod, you can throw farther than you cheap small flashlight can throw.
as far as the brightness in lumens? only some people who has the sphere can tell… anyone with the sphere want to take this challenge?
Ok, without the lens it measured 438 lux and with the lense 299. I'm not sure why I needed to prove this as this is basic science... Nothing is 100% inefficient.
Goodness MEN why all the dispute……You all saw each others points of view but argued over separate topics……
Single asperic lense in front of REFLECTORED flashlight = no worky……
Double lenses in front of REFLECTORED flashlight = Worky quite well……
The first lense is needed to focus all the light into a smaller more focused beam while the second collimate the now equally converged beam into something that will project at a given ratio. Thus eliminating the distant focal point. I am no scientist but this makes sense in my head, likely not all yalls though because I typed what terms I know which may or may not be proper.
HOly crap… it’s cold out here tonight and so freaking windy… but in the name of science… i decided to throw another experiement.
this time i’m using another small flood light Ultrafire HD2011 got it from Wallbuys special promotion for $9.99
but this time i’m including light meter at the end of the spectrum. it’s PIA since i have to keep on going back and forth between the flashlight and the meter to take the picture… same distance… about 80’ away and this time to avoid any confusions, i’m going to use my mod instead the telescope
HD2011 before ( notice there’s no hotspot as HD2011 is a flooder light)
the light meter measurement at 80’ away
HD2011 inside the tube
HD2011 beam shot ( notice the hot spot)
HD2011 light meter measurement at 80’ away
SkyRay King at 80’ away
SkyRay king light meter at 80’ away
now you guys can throw all this science about lights at me… but the meter don’t lie, the device is working using just one magnifying glass at the front tube.
Ok daylighter, you were right in regard to flooders. A floody light will throw further that way, but anything even remotely throwy (like a C8) will not benefit from this. (As shown by my beamshots)
all the decent thrower i have doesn’t throw as good as flooder light, but nevertheless… the hotspot certainly appeared much brighter at the distance around 30’–50’ away… the meter says so too
