    For my next project... a little help please..

    Can someone from here or MTB explain to me how to work out which LEDs (when grouped together) give better spread and which give better throw.. and how to work out their various real life colour on the ground (that is warmer or colder looking)

    I am trying to overcome a few short falls which are minor but annoying with my current setup.

    Previously I had a Lupine Wilma and a Trail Tech Eclipse 30w HID. Together they gave a good wide short range spread (Wilma) and very good long range (HID) but lacked a little in the middle ground.

    Now, I still have the Wilma and a 7UP (XPE R3) now I still get the wonderful wide short range (and I love the colder colour) and really good mid-range (7UP – which is warmer in colour) but that long range has gone (by long range I mean 250mts plus).

    I would like to drop the Wilma and keep the 7UP but wondered if it was possible to swap out any of the current LEDs that are in it so as to get the wider spread and colour of the Wilma and some of its (7UP) beautiful mid-range.. and then bring back in the HID for the more serious long range stuff..

    So my question is really, is this practical, possible or just a waste of time… or should I look at a custom made LED setup which uses either more or different LEDs.. noting that at 30w my HID gets warm but never as HOT as the 7UP and I am conscious of the LEDs heat build up (even when moving quite fast).

    Any help appreciated..

    250 mtres is a long shout for any of the leds to give a real throw that far you would be looking at using Aspherical lenses and then you would get a very narrow but long throwing beam like this .



    now that tree is an estimated 200 mtres away may be more .

    This is by the way one of Saablusters Lights off CPF the worlds longest throwing Led flashlight . but you would not want to use it on a bike .


    Great for spotting rabbits and the dog .
    Also lit up an airliner at 1000 ft ( estimated ) flying over head .

    One of these using the 12 mm asphericals will come close to the throw you are after

    .




    and match the other one on the bars

    Thanks for the input Chris... would I adapt the one I have to match what you are showing above or would that be a new light set..?
