    MJ880 clone is not exactly clone. MJ880 has optics, clone has OP reflector with glass.
    MJ880 has the best beam and also led tint is the best in my opinion.
    But the price difference is huge 170EUR vs 30-50EUR...

    Does MJ880 have optics similar to gemini duo clones?

    Very well put together guys.. thumbs up for the effort! I have the MJ880'clone' on the way. Lots of great info on these threads, it certainly helped me make an informed decision. This will now be my second light thanks to these threads and hopefully i'll be as happy as with the first one (mini cree).
    Once again kudos to you guys here and in the other threads as well!

    Great and timely thread.
    How is the included Yinding helmet mount? I assume that the 1 x Headband (40~80cm) is a helmet mount. Kind of looks like it. Or is that intended to mount it as a headlamp?

    Recently I did interesting measurements of my SS X2, KD 880 clone and Skyray S6 - they seem to have the highest brightness at 7.0-7.1V power source (they take 2.4A, 2.4A, 2.6A on high). Other lower or higher inputs decrease the brightness. Posted here without shots for now, but after a night ride with 7.0V power source I'll try to update it ...

    Yes because there are 2 leds connected in series with buck driver that needs about 1v overhead (3v for each led = 6v for 2 leds = 7v on input) or it will go out of regulation and leds will start to dim below 7v. Higher input voltage shouldn't decrease the brightness but it will decrease current.
    We really need a FAQ for chinese lights in this forum...

    This means that eficiency of the driver is about 6/7*100 (85%) at 7V. With higher voltage the lights seems to drop a bit/not much as by lower voltage.

    I tested original Yinding battery and its capacity is around 3500mAh. Green indicator light goes red at around 6,2V. Charger charges battery pack to 8,22V and when charging completly empty batteries it overheats and alternating on/off (red/green). I drilled some holes to add some cooling and we will see if it gets better.

    I was also thinking of getting a better battery pack, holder and charger for this, but no idea what and where to buy from.

    Please add any reviews or links to any great reviews that worked their way down the line. This way will we have a great resource to Budget Lights, the same that we have for the higher price lights

    i just bought the Samsung 7800mah hard shell. Nice powerhouse pack. Also as others have mentioned, action led also has some great quality batteries. I have bought lights from both these shops and use the chargers that came with the setup..

    Excellent.

    I would like to buy just a case to use my protected 18650 batts with it. I would rather do this as I have a charger at home already for 18650 and can always add batts to my collection.

    Any recos on just a case to take 4 x 18650?
