    Reflectors and lenses

    Hello, I would like to ask you a question. I 'm building headlights, currently I only have 4 led's 3W which emit light 140 degrees. So i need reflectors with or without lenses(don't know the practical difference only theoretical). In my local shop I have these options:

    Which of them would you suggest to buy?

    Welcome Zmogedra

    What sort of riding?
    For road go with the narrowest. HPH3.
    For trails you want wider but not more than 20 deg. HPH1 and HPH2 mix might be good.

    A few Dynamo builds and some Small battery lights
