    Nitenumen mod with Gloworm XS elliptical/flood optic?

    I'm inspired and hopeful that the Nitenumen's wide/down angle light can be modified to use Gloworm XS elliptical/flood optic or similar to achieve a sharper cutoff than the factory wide lens. My rides would be 1-2 hr on city streets, combined with unlit paved paths where a long throw is good to spot flesh and blood obstacles in the path way before I get to them. Really helpful if it's groups of 2 legged animals I want to avoid.

    But that far-reaching throw isn't so good for oncoming traffic, so i'm looking for a hi-beam/lo-beam setup, and the Nitenumen dual switch / dual light seems close to fitting the bill.

    Is this likely, or worthwile mod, even if I have to cut/shape the Gloworm optic to fit? (i.e. hack with a dremel and sandpaper)

    These are the threads I read through. Thank you for such great details. This is one alternative, or maybe just go with one of the Fenix shaped beam lights, but I don't think they would work as well.

    Anyway, it's an idea.... and if context helps, I promise to ride the singletracks on my mtb at night with it...

    Easiest thing to do is to put an elliptical lens in front... these will just widen out the beam.

    Hi znomit! I had no idea: "L2 Spot Base Module Lens - Oval 8X25 Degree Viewing Angle," less than a buck, no shipping charge. This says 25 deg, so I think I don't understand - if my beam angle is 90 deg, how does this make is wider? (cheap to test obviously, but I would like to learn a little about mod'ing LED lights.

    I'm about a month away from purchasing, so lots of time to read and change my mind more than a few times. Ya, I should just purchase and get on with it, but am ordering a small pile of bike tools so I can quit borrowing my boy's tools.
