What does a strip lens do?
Make a horizontal beam pattern like a good car headlight.
And as a result reduces the light shinning in an oncoming cyclist’s eyes. If you are only riding on the street, not likely a big deal. If you ride on bike paths, your fellow cyclists will appreciate it, or at least they won’t curse you because you don’t have that feature. I think the Fenix BC30 mentioned above is designed to avoid light in the oncoming cyclists eyes as well.
No, it’s not. You can’t assume everyone is running their bike lights at full blast. My bike light mode is pulling 0.2 amps, tilted slightly forward. The spill is not going to blind anyone more than an average car light.
Required amount of light is very dependable on scenery. To have a ride on paved (even) roads 0.2A can be sufficient. To ride in woods you need much more light to see the path well.
Could someone post a beam shot using the striped optics and possibly the light with the optics used?
I went to Carlco and they show a “striped optic family” but I am not sure how you would integrate with a flashlight, they don’t look compatible.
Thanks,
I ride on side roads as well as the woods. That’s why I really like the flood from my Zebra SC600w Plus. Not only does it illuminate off to the sides a bit, but also overhead where branches might be hanging down.
I find my most used mode is 700 lumens. That’s a little over 1A current from the battery. I couldn’t imagine cycling with 5x-10x less than that, though I probably did as a kid when there was nothing better.
Is this a direct fit for Convoy S2+?
Yes. Direct fit.
My TN4A with and without striped optic. It is just a flat lens cover with a stripped countour to it. phone set on auto, but this is likely about the intensity difference when you spread the beam out also.
Here is an S2+ with and without striped lens:
True indeed! Only objecting to the statement that spill will blind people (without mentioning anything about output). 0.2A is sufficient for me on paved bike roads in darkness riding fairly fast, but I sure would turn it up a bit if I was going to ride in the woods in darkness. I wouldn’t be as concerned about blinding people in the woods though.
Thanks. What tool do I need to unscrew the driver/pill in order to get to the lens? Retaining ring pliers, I’m guessing?
Thanks for posting the beamshots and links to optics.
I hadn’t thought about TIR lenses working this way, it has given me a few ideas for biking and running and possibly materials/project inspection.
