    2 things:
    1. If you place a very small magnet on the flat-top, it will create the necessary contact (not sure about resistance issue but I've done it)
    2. If you remove the capacitor from the chip, I believe it will only allow bright mode as it will always think it is being turned on for the first time.
    Love your videos buddy!

    I have the exact same two kinds of torches. Something broke yesterday in the newer model, the led now is constantly very dim. Maybe that the ic has broken down but have to do a teardown and research / repair. I like these models and was a bit disappointed it quit so early after only maybe 10 or 20h of use (not continously of course).

  • @a000ab

      Of course in full power mode the current should also be DC. So, his guess could be right.

    I wonder how the chip remembers what power cycling state it's supposed to be in? Would putting a resistor between 1 and 2 or 3 and 2 possibly help it forget? It would be ideal if it could just forget in half a second and you had to switch faster to get into the alt-modes.

    • @DiodeGoneWild
      @DiodeGoneWild  6 років тому +1

      The capacitor allows it to remember the state. If you used a lower value capacitor or if you put a resistor in parallel to it, the memory would be reset faster.

    Thanks for a very good review again! I happen to have both types of led-torches, all work fine but i am afraid the higher power of the new led is a bit too much for long life. Anyway its a very good quality for that low price. I also bought a much more expensive one for around 7 Euros, which claimed to have 5 W. It turned out that there was no contact from the led-heatsink to the metal casing - the thread in the heatsink didnt fit into this of the case - it was just sitting loosely inside! The led's heat burnt itself off the pcb and the little plastic lens melted away! Now and than you can find such shitty construction from the chinese manufacturers - even with more exensive lamps! The skywolf imitation is really one of the best for the price-class!

      Lol for 5x the price? :)
      I have convoy s2+, and two of these. These comes quite handy as a drawer flashlight you could have at any station, and they are quite powerful! I use them at lower setting. The only bad thing I could say about this flashlights is the color of the LED, they are quite bluish, one more blue then the other. But that depends on the batch I guess, the one on the video appears white.

      It will never discharge it below 2.5V because at this voltage the LED draws no current. Below 3V the current is already very low.

    Cree XP-E diodes i think, or copies of them. I know its not a copy made by LatticeBright becourse yours has round small dots and LatticeBright uses square dots. I dont know of any other LED chip copy factory. I bet both is copies, but if i should pick the real one if any of them is real then my pick is the new one, it seems to be the most right size die.
