Experiences

Tested from: 2018-8-15

In 2015 I had some exchange of emails with a reader about the battery powered version, which was the only version there was at the time. I wasn't and still am not very interested in battery powered taillamps, so only recently when I saw that there is a dynamo powered version, I bought that.

This is a good taillamp, it looks to have similar optics as the Solo. The light colour,??????? many taillamps go too much towards orange for my taste, many recent taillamps from Spanninga and Axa (The Lumiring was more red, the earlier Spanninga Solo and Lineo are more red too).

The bolts and nuts and washers should be stainless steel... (or at least brass)

In build quality it looks good:

Beam shots

See the camera settings page for more on the setup and settings to make pictures of the beams of taillamps.

Note: I didn't make beamshots, yet.

Comparing taillamps

Design- and thus review considerations for taillamps

See Theory for taillamps.

Conclusion

The Spanninga Duxo is good in beam pattern and quite cheap, cheaper than the other Spanninga taillamps. The curved surface of the reflector/lens means as little white reflection seen by following traffic. I don't like rust so I'd like to see stainless steel mounting hardware but that's not a big problem. Recommended.
