Hi, friends, I am George, designer of D.Q.G series of flashlight. I am very happy to recieve emails from lots of friends, they will told me they like my design, or discuss many topic with me, about flashlight, about universe, about history of human, about mankindâs awarenessâŚâŚ
this is my first thread on BLF, its about the problems of DQG Tiny 26650 V3.0 that feedback from many friends or from other methods.
one important problem is the flashlightâs driver will drop out if you open the light. like picture as below:
I am very curious why it can open like that. this light is assembled by 3 main parts: light head, battery tube, and tail cap. but the question is the light head and battery tube is glued when on assembling, it cannot easily opened only by hand. so, only tail cap can open to put the 26650 battery into (the SS ring cover at light head is not glued, the LEDâs optics maybe have some small dust, if you want to make a clean, the ring cover can open, and take the lens out to make a clean).
to be honest, there does have aroud 10 pieces of lights is not glued. but both of them are all in China market. the tragedy is happened as expected, some of friends distoried the driver after they screw the battery tube out, and then crew the tube on without make a study to let the driver in right position. after these events, I decided to glue every lights of Tiny 26650 V3.0 in order to avoid this event.
So, now I want to tell all friends: please do not try to uncrew the light head and battery tube, it will break the driver if you uncarefully put the driver on position. if you have opened it, please according to below method to put battery tube on: first use finger try to make the driver in right position, the switch on driver board right toward the button on the light head, then push and hold on the driver, use a pencil or other streight stick instead of your fingerâs push, then put the driver cover ring (copper) on, then let the battery tube through this stick and slowly crew the tube into the light head with the push of stick keep on.
Tiny 26650 V3.0 is a single lio-on battery flashlight which nearly reach the limits of its output in all kind of conditions (battery discharge ability, driverâs drive ability), so, please donât try to open it to study if there have any can to reach more output, although there does have a little ability to reach more if you are lucky got amazing perfomance of driver and amazing low VF leds.
NOTE:
- the light only can take the battery length above 65mm and within 70mm. if you cannot light it on, please check the battey length, and confirm if you crewed the tail cap tighten enough or not.
- suggest use battery without protective, due to maybe protective battery have current limit at the protective circuit, that will let light cannot archive turbo mode (it need aroud 10A+ current in some condition)
- many electic components is special choiced in orde to build a powerful light as small as could, that mean these components is not so easy to resource, so, do carefully to treat if you decide to open the light to make a study.
nearly 6 years from DQG first light untill now. I am very happy that many friends like my designs. although I need to assemble every lights myself, cannot hire people to extension my dream, but I am still luckly have time to understanding what is our world running indeed.
the important thing I want to say:
thank you very much to those friendâs encourage and stand by, without yours, I cannot adhere for long time, your tolerant and understanding to every shortcoming of every DQG lights keep me move.
best regards to everybody,
George
