    Hi All
    I found this finding fascinating - has there been no responses because it's a spoof? If it's not a spoof then it seems quite amazing.

      I myself wait for replications. Too many spoofs around to waist time energy effort on a total waist of time. I have learned much from the Mylow story, if many can replicate, and the many are trust able, then you have the real article.

      Would be nice if it is real. I have one of these flashlights, but not two.
      See my experiments here...

      You do not have to prove something for it to be true. However, you do have to prove something for others to believe it true.

        I only have one of these flashlights also, so I have ordered 3 that look the same make - hopefully be able to try this out at the end of the week.

          I have a crank flash light that i got a few years ago. When i first got it the capacitor i believe its called was already charged. It worked fine without needing charged for the longest time. I never counted the exact amount of time but it undoubtedly was hours on end.

          if the flashlights in the video are already fully charged, theres no possible way to know weather its a fake unless you do it yourself. It looks like his 36 hours video was his last update..I dont know why that person wouldnt tell us the exact amount of time it took before it died. That upload was from over a month ago..

            I invited this inventor to comment on his finding. Also report as to the results of others since he selling some information and is a source for the shake lights.

            Personally I am always skeptical when money is involved - but the nature of these claims are interesting. If the results are easily replicatable (low cost/time), obviously it may be worthwhile to pursue.

            Hence me posting it here.

              Experimental Report

              I sourced four of these lights and noted the following.

              -From a single charge (2 minutes of shaking) 3 of 4 lights demonstrated usable light for 10-30 minutes, visible light for more than 20 hours.

              -I could detect no resonant coupling effect that affected duration or intensity of light. Only a slow dimming as the capacitor gave up its charge.

              -However, when the flashlight coil was placed near another coil setup (non-toroid joule thief) at resonance, the light grew noticeably brighter.

              Nothing really new, but I now have four new chinese flashlights...

                Someone postet about the same thing at ou.de
                but the conclusion at last was, that it is a Hoax.
                Someone was at his Track.
                Theorizer are like High Voltage. A lot hot Air with no Power behind but they are the dead of applied Work and Ideas.

                  Reproduction of Video experiment

                  Hi All

                  My 3 shake torches arrived today. At 11:50 this morning I placed 3 side by side as per the video, passed a neo over them a few times. I have just got in at 5:30 and they are all still bright! So that's 5 hours 40 mins of light. My old shake torch only lated for a few minutes per charge..

                  So either:
                  1. The super caps hold a huge initial charge.
                  2. There is an effect here of note.

                  I will tomorrow, (see what happens overnight) discharge the 3 torches and start from nil charge. At the moment this seems interesting, but as I say I do not know how long the LEDs should light on the initial charge.

                  Just to update. It is now 04.50hrs the next day so they have been on for 17 hours so far. The lights are still throwing a beam 6 ft away, illuminating a circle about 8 " diameter. This is not at full brightness, but maybe less than lastnight - difficult to tell without a lux meter.

                  Update now 10:50hrs, lights still bright after 23 hours. Not as bright as when first started, but lights still cast a lightpool at 3 foot in an area with poor natural illumination. So still the question is how long would the torches capacitor power the LEDs for if fully charged? I noticed on the net that some of these types of torches can be recharged and are good for 5 hours.

                    Hi David

                    What do you define visable light as? Is the LED just glowing?

                    Many thanks

                    John

                      Light update

                      At about 4.00pm today one of the lights went out. When I picked up the un-working torch, the torch furthest away from it started to flicker.The torches end cap was loose, tightening it lit the LED momentarily. Moving the dead torch slowly once to move the magnet brought the LED back on. While replacing the torch back to its previous position the LED went out, moving it away it came on. Tilted torch again, LED on, Torch furthest from it then went out. Replaced torch, picked up the new dead torch, Tilted it once then LED on again.Replaced torch with other. Ran a neo 3 times across all 3 torches, all are illuminated.

                      As I have said previously, I do not know how long the cap should light the LED, but there does appear to be an effect here. It is now almost 30 hours except for this one fiddle and they are still projecting a beam of light onto a wall 6 foot away. Seems to me good going, but I'm willing to be corrected.

                      ..

                        Ok we are nearly at 48 hours and they are still lit. This morning one of the outer torches went out, just by picking up the torch and and moving the magnet slightly, 2mm by tilting but not through the coil, the LED came on flickering. I ran a neo over the coil 3 times and the LED is stable. When picking up this torch the opposite side LED started to flicker. All are now stable. I am quite convinced ther is an effect here. Using a radio off tuned on MW I get an increase in static volume within 3 ft of the torches, also a clicking sound is heard which may or may not be related.

                        As there has been no responce here, am I being an idiot and you all know LEDs will stay lit for a long time or is there an effect here worth further investigation? Out of interest does anyone have a photograph of the inside of a reedswitch, the sort used in these torches?

                          "Is the LED just glowing?" YES.

                          Actually this whole thing has taken me in a new direction. If you take apart these lights on either side of the switch are points of contact for the capacitor. This makes monitoring the charge at the capacitor quite easy.

                          Just out of curiosity I placed the flashlight coil next to a little joule thief coil I built. The little circuit runs on 2-3v but charges about any kind of lead acid battery (7-105 Ah).

                          So while charging a battery I located the coil of the shake light right next to the coil of the joule thief - it immediately charges the flashlight cap. After leaving it by the coil for longer periods of time - I have found the light to give a much longer usable light. Almost as if the cap is conditioned.

                          Now these lights each capture and hold 3-6 volts for 10-20 min (each). It would seem that they may be able to power the joule thief circuit so that it becomes self powered. Or not.

                            See if you can take apart one of your lights and monitor the voltage to see if you can measure some kind of inductive resonant effect.

                            If you have the same light I have... unscrewing the LED end removing the lens and tapping that end hard against your palm should produce the assembly insert all in one piece.

                            My Model Torchlight is 5188

                            Looking forward to your response!

                              Thanks for responding because I have found this exercise very intresting, and one of the few things that has impressed the other half!

                              The LEDs are still bright, not fulll brightness, but enought to cast a light pool in a dimmly lit area in day time. See attached.

                              I do not want to take them apart yet - want to see how long the centre light will keep going for, 52 hours so far.

                              Regards
                              John
