Herrmans H-One S

Hello,

Doe anyone have, or know of, beamshots of the Herrmans H-One S (75 lux version)?

I am looking for a replacement of my 2004 home made Luxeon headlight, and are considering the B&M Luxos B and Herrmans H-One S.

So far I have not been able to find a review or beam shots of the H-One S. The specs and the price (less than half the price of the Luxos B) make it an interesting candidate.

Regards,

George

Here is a start of a review

The reviews on Amazon seem less enthusiastic than I'd expect for a cheap metal lamp: Some comment about flicker, and wonder if there even is a rectifier.

See the pcb? I'd prefer to see metal or ceramics there, too.

beam - somewhat narrow, as you'd expect from the optic, and for a cut-off beam, the middle portion of the beam appears bright, the faraway portion of the beam not being sufficiently intense to create maximum low-beam range.

Herrmans need to put up a test against Cyo-R on youtube, I suspect the H-One-S would look like a winner.

I had found the add on ebay, but I did not click on the details (because I wasn't planning on buying it on the other side of the world when I can get it cheaper in my own country), so I missed the images.
The light pattern doesn't look very impressive. The beam is narrower than I have now. The specs image says the beam is 20 x 3 meter. Does not look like a winner to me, when I compare it with the (maybe biased) images on B&M's site.

And what do they mean with "6V/3W (2.4W with our without reat light)"?

The review on the swhs site unfortunately has broken links for the beam shots.

Peter White has Luxos beam shots, but no H-One S. So comparing the two is still difficult.

What I meant to imply is that the H-One-S will likely produce a brighter spot on the road than the mediocre, but popular Cyo-R - which seems enough to persuade buyers into knowing that the brighter one is better.

Best guess would be: 3.0W without a rear lamp (0.6W) - all nominal values.

swhs site's broken links seem to be placeholders for future entries.

I like a wider beam instead of a narrow bright spot. My wife's bicycle has a Cyo R. I tried it on a dark countryside road. When I drove in the middle of the road, the beam illuminated the whole width of the road.

I will wait for the results of swhs's tests. Yesterday I found this site: mini.xml.in. Seems promising.

Sorry, I can't really recommend looking into the .in link.
You can watch the same thing on youtube,

Some kid's home-grown designs, compared to the Luxos B. However, the video is almost useless and plenty annoying already, without that dysfunctional, ad-heavy site of his around it.
That sidewalk-riding Schadii guy must be quite young. Hopefully, he'll still learn a lot about optics and video editing.

If the basics of photography are not understood, why do people venture to take videos? My fault, I never should have mentioned the word, video, in the first place.
Oh well, while waiting for more meaningful reviews or isoplots, I'll just listen to some audiooooo...

Any particular reason for that?
The domain xml.in is registered to a German company (QE GmbH & Co. KG in Osnabrück). The subdomain belongs to a guy from Saarbrücken, also in Germany.

How do you know without looking into the .in link?

I agree that the videos aren' t very useful. However, when looking at some of the images on mini.xml.in (without judging the photographic quality), I see a homemade light with sharper beam edges than mine (and a lot of other lights). I am mainly interested in what optics he is using (and if there is a version with a bit wider beam). With those optics I could probably aim my light a bit higher, having a longer beam, without blinding oncoming traffic.
