Hi all,
Has anyone used or have any information the below lights? It almost seems to good to be true they are reduced to £89 for a 2000 lumen set of lights. I have tried the ebay option and after one ride in the british winter the on off switch broke so the lights are stuck on the lowest output setting thus rendering them pointless.

    Looks promising but try this one. Me and a mate have one each and it is great for the money.

    Not 2000 lumen off that battery pack, (maybe 1600) not happening, nor will it last long (about 2 hours) making the second LED rather pointless.
    Currently riding a Whyte T130C, X0 drivetrain, Magura Trail brakes converted to mixed wheel size (homebuilt wheels) with 140mm Fox 34 Rhythm and RP23 suspension. 12.2Kg.

    can you advise why this wouldnt acheive the 2000 lumens is there not enough voltage or does it need higher than 4,800mAh or both? may be a dumb question but dont know a great deal about lights.

    The current required exceed that which the batteries can produce continuously.

    4800mah is the capacity (size of the bucket) not the flow rate (the size of hole in the bottom), I'm not an expert on this, supersonic (see big lights thread) is one of the more knowledgeable.

    Not bad but you could pick up a similar twin head unit for £30. XM-L2 based lights will get you more runtime at a similar brightness due to the more efficient design. It's possible to get 2.5 to 3 hours off a reasonable four cell pack with a twin head XM-L2 over a older XM-L variant (such as the XM-L U2). Though i'd still go for a six cell pack with a twin head light anyway, if you plan to be out for any length of time. For that reason it's often better to find somewhere that sells the light and battery seperately so you can get exactly what you want.
