Headlamps with cutoff for dynamo


2.v.1 Dynamo headlamp: Schmidt Edelux

Tested: From July 2008 (used regularly since the test). Sunup compatible: Yes

This headlamp was the best dynamo headlamp from mid 2008 to fall 2010. It's still an excellent choice but there are other options that are about as good. The Edelux, since ca. end of 2009, has a different reflector which has a longer beam (good) but also a big hotspot (very bad!) so in my view it's not as good any more as the one I tested. New beamshots of the original and version with later reflector to come to compare with the Edelux II, once I have the Edelux 2 and when the weather allows beamshots (dry roads).

2.v.2 Dynamo headlamp: Philips Saferide LED dynamo (abbreviated: SLD) = Philips Saferide 60

Tested: From 22 October 2010 (used regularly since the test) Sunup compatible: Yes

This headlamp is one of the best currently available dynamo lamps with cutoff. Strong light beam up to ca. 45m, so it has a throw similar to the Edelux, too much light near the front wheel (but you only really notice this when switching to another headlamp while riding), no automatic on/off, the original mounting bracket is not stiff enough, the later one is much better, the lamp lets light go upward to your eyes (can be fixed with some black tape or paint). Conclusion at the end of 2010: Due to the low price compared to the 2 main competitors (Edelux and E3-pro-StVZO) and as it's about as good as those 2, this lamp for me is the best value for money. End of 2012 this conclusion was still true after testing the Luxos B.

2013-9-28: My conclusion after testing the Luxx70plus and Luxos U: In beamshape the Saferide 60 is superior to the Luxos and Luxx70plus, it is far more comfortable to ride with, but the Luxos U and Luxx70plus have the advantage of a USB power output. If you don't need a USB power output then the Saferide 60 is the best value for money.

2013-9-28: I'm wondering after having tested new version of the Saferide 80 with neutral white LEDs, whether the dynamo lamps have also been changed with lower colour temperature LEDs. I suppose I should try a new Saferide 60...

Tried it, and yes, the Saferide 60s are since at least manufacturing date week 46 of 2012, made with neutral white. Cool, ride report to follow.

2.v.3 Dynamo headlamp: Trelock LS 885

Tested: From 17 Nov. 2010 (used regularly since the test) Sunup compatible: ?

The beam shape is nowhere near as good as that of the Edelux or Philips SLD, but it is relatively cheap and produces a strong, usable beam, so this a good choice if you're on a budget.

2.v.4 Dynamo headlamp: Busch & Müller IQ Cyo RT (= Cyo Nahfeld with daytime running lights)

Tested: 17 Nov. - 6 Dec. 2010. Sunup compatible: Yes

Worst bicycle headlamp I've ever seen despite the fact that it gives a wider and brighter beam than halogen lamps. The beam is a weird trapezoidal shape with very sharp cutoff and very sharply defined corners. These give a feeling of being trapped in a tunnel of light. I suppose it's hard to imagine that if you haven't experienced it. The sharp corners and the fairly strong hotspot attract your attention which is bad. The daytime running lights are annoying because of their colour (blue with a bit of purple), and because they are not diffuse and point sources of light. The beam is very weak, especially if you aim it far (so that you have light up to ca. 40m), it is much weaker than the Edelux, Philips SLD and Trelock LS885.

More details: Dynamo headlamp: Müller IQ Cyo RT (= Cyo Nahfeld with daytime running lights)

Note: This review is of course only relevant for the Cyo R and RT (for the R, disregard the parts in the review about the daytime running lights) which is the near field version of the Cyo (= 40 lux Cyo), not the Cyo sport (= 60 lux Cyo). The Cyo 60 has the same beam shape as the Edelux and is almost as bright as the Edelux.

Note 2: Someone in a German forum mentioned the tolerances in LEDs/electronics cause my view that the Cyo R/RT is so dim. Not true. It's related to the light output and the surface area over which the light is spread when you aim this lamp such that you get light to about 40m (and compared to the Cyo 60, the retro-reflector/diffuser must cause some losses, further the beam is fairly wide at the end of the beam, which is not useful unless the LED produces more light, i.e. the light gets spread too thinly and thus the intensity on the ground is too low). Variations in total light output due to deviations in LEDs or the circuitry are inconsequential due to the logarithmic nature of human vision. If the LEDs were to produce 5% less at a given current, and the circuitry also 5% less current, then the total loss in light output (lumen) would be less than 10% and the total loss in perceived brightness just a few percent, i.e. not really noticeable...

2.v.5 Dynamo headlamp: Supernova E3-pro StVZO compliant (2010, supposedly 305 lumen)

Tested: 22 Dec. 2010 - 24 Jan. 2011. Sunup compatible: Yes

Good strong light beam to about 25 m (weak at longer distances, therefore I do not recommend this lamp for those who like to ride fast at night), not too much light near the front wheel, very weak standlight, no automatic on/off, the multimount is good (the also available bar mount is poor), expensive. At the end of 2010 until late 2011 this was one the 3 top headlamps, approximately equal to the other 2 which were the Edelux and Philips SLD (each has their strengths and weaknesses, so there are large differences in various aspects between them!). Since late 2011, various much cheaper lamps (esp. H-diver, Saferide 40) are available which are at least as good as the E3-pro in beamshape, though not in housing, and the housing is really what you pay for with Supernova.

2.v.6 Dynamo headlamp: Busch & Müller Lumotec oval senso plus (Halogen + 5 mm LED for standlight)

Tested: Spring 2010. Sunup compatible: Yes

This headlamp is an example of obsolete technology... Not actually suited to riding on unlit roads, and not at all suited to riding on parallel roads where you're being blinded by car headlamps. The picture on the left was made on a wet road 3, its beam barely gets captured by the camera, the difference with good LED lamps is just astounding. It is obvious that even on a dry and ice free road, you don't get good/enough light. You should compare the beamshot with those I made of this lamp after modification with a neutral white LED on a wet road 2, which gave an enormous improvement.

2.v.7 Dynamo headlamp: Herrmans H-diver

Tested: Since 10 Feb 2012 (used regularly since the test) Sunup compatible: ?

Although the beam shape is fairly pleasing, it's not good enough for unlit country lanes (not strong enough at distances of 30 - 45 m), and I have doubts about the durability (weak housing) and the quality control doesn't seem to be great either from the problems I had with the housing in 2 of 3 headlamps. This means unless you can't afford a better lamp, I would recommend a Trelock LS885, Cyo 60, Philips Saferide 60 (in increasing order of price and functionality). The Philips Saferide 40 is probably better than the LS885, but more about that in the future. Update Dec. 2012: I was told the composition of the plastic of the lamp's housing in early versions had some issues, and was changed...

2.v.8 Dynamo headlamp: Herrmans H-one S


Tested: 60/75 lux version since 23 Aug. 2012, 75/95 lux version: Since 2 Jan. 2013. Sunup compatible: ?

60-75 lux version (lux values are with/without taillamp): I don't particularly like the beamshape, and for some reason despite the high lux claim the illumination at 40m seems pretty weak compared to Saferide 60/Edelux. I think this is because the lux rating is a short peak as opposed to maintained over some distance. I mentioned such issues before, somewhere else on my website...

75-95 lux version (lux values are with/without taillamp): Mid-late November 2012 a new version of the H-one S arrived. I had already heard it was a big improvement though the reflector looks the same, the LED is different, bigger, more yellow. This headlamp may have been the first factory made dynamo bicycle headlamp with a neutral white LED, and it kicks ass in the rain and is more pleasant than cool white under all circumstances.
[ update 28-9-2013: The Saferide 80 with neutral white LEDs may have been available at that time already, update 2013-12-13: The dynamo powered Saferide 60 may also have been available at that time with neutral white LEDs ]

2.v.9 Dynamo headlamp: Dosun U1


Tested: Since 9 Dec. 2012 (test not finished). Sunup compatible: ?

Excellent construction, but I'd like to see a beam of even width, not a pinched section that the U1 has. Regarding beam I would prefer the H-diver...

2.v.10 Dynamo headlamps: B&M Luxos B & Luxos U



Tested: Luxos B: Since 19 Dec. 2012 (test in progress), Luxos U: Since ca. 15 June 2013. Sunup compatible: No (at least the U, not sure about the B)

Luxos B: The cutoff is very sharp, but then, the reflector is huge (the larger the reflector, the better you can make the cutoff). Bad point is the strong hotspot and those daytime lights are not what I would want to see (see my suggestions elsewhere for what the optimal daytime light should look like, namely more like a good taillamp), but at least those daytime LEDs give white light and not blue/purple as with the awful Cyo RT that I tested and you don't get the direct light from the LEDs, which gives the problem of far too high luminance. But they are still of variety 'visibility by being annoying' which I don't like. Especially at night these are very annoying (and yes, they light at night because they don't just serve as daytime lights). The beamshape is very wide. In the rain the near field's exposure gives a big problem as it is far too bright in that case due to the rest of the beam not showing much from the road due to wetness and the light colour (see also the review of the H-one S). The artefacts near the bike also become very distracting in that case.

Luxos U: For this lamp all that goes for the Luxos B is also valid here, the Luxos U just has some extras: The Luxos U has a handlebar mounted switch/USB output. It also has a high mode which is made possible using the internal battery and it has 'panoramic' light (more light near the bicycle) which I didn't really notice except at about 6 km/h which is useless, but it's useless anyway as the Luxos overexposes the near field quite close the bike already. The handlebar mounted switch has a bad 3.5mm connector and the electronics is way too sensitive to it getting even slightly damp resulting in the lamp only flashing on and off. The Luxos kept unimpressing me regarding beam shape and comparing it to the Philips LBL (even though that is battery powered) made clear how pathetic the Luxos' beam is in every aspect except sharpness of the cutoff compared to this lamp from 2009. The overexposure near the bike is unbelievably bad and the irregularity of the beam too. The Luxos looks good on B&M's beamshots, but those do not represent what you see in reality. This is in general a big problem. I will make new beamshots on a gray and wider road and a bit more behind the lamp, which should show the artefacts better, as you can see them in the still from the video I made. The USB power output works, also when the lamp is on, but in the latter case it doesn't always work properly as I found on a long trip. Still the USB output makes it worth buying, but if USB power output is not important get the Saferide 60, or if USB output is desirable but not important at night then the Luxx70 plus is an option.

Additions: 1. My Luxos U died end of October 2013... 2. I forgot to add from a test long ago: The glare from the Luxos seemed OK only when just the main LED was lit. It was really bad with the DRL lamps lit, which do light up at night ('panorama' light)... 3. I got an email about the Luxos not working on the Sunup: Yes, it needs AC it seems and as B&M mentions. Many lamps work on DC but they are made for an AC dynamo, and I suppose a list of which lamps work on the Sunup, would be useful.

2.v.11 Dynamo headlamp: Axa Pico 30

Tested: Since 17 March 2013. Sunup compatible: ?

Summary to come.

2.v.12 Dynamo headlamp: Sheng Li: banklight LD-101


Tested: Since 19 April 2013 (test is in progress). Sunup compatible: ? If not via dynamo input, then connecting the Sunups output to the USB input if that can handle 6V?

Lamp with internal 3xAA batteries that can be charged via dynamo, USB. The lamp can also supply power to devices via an USB cable, either a separate USB output, or a combined dynamo input + USB output cable... This is quite cool. The light of the lamp is cool white, and the beam pattern is nothing special, comparable to many middle class lamps, and not as good as the Saferide 40 / H-diver, but the qualities of this lamp are in the total package with USB input and output. Test is still in progress.

2.v.13 Dynamo headlamps: Axa Luxx 70 plus


Tested: Since 4 Jul. 2013. Sunup compatible: ?

Useful beam, reach is about the same as most dynamo StVZO lamps, ca. 45 m. Beamshape is not as wide as the Luxos, but also has fewer sharp artefacts (which are the annoying/attention grabbing ones). It's a bit comparable to the Trelock LS885 which I recommended as a good budget choice, and this beamshape is better than the LS 885 but compared to the best lights clearly not as good in width. The price with USB output makes up for that.

2.v.14 Dynamo headlamp: Schmidt Edelux, with version 2 of the IQ reflector, 2013

Tested: From 14 Dec. 2013. Sunup compatible: Yes

Not long after the Edelux was released, sometime in 2009, the reflector was changed as had happened with the Cyo earlier (but apparantly a different reflector), see my IQ reflector page. As the Edelux II with IQ premium reflector has been released, I thought it would be a good idea to take the last version made of the Edelux, so a 2013 version which has the latest LED (higher bin) and the 2nd version of the original IQ reflector and do a 3-way comparison with the Edelux-2008, Edelux-2013, Edelux II.

Experiences: It is not as bad as I thought, the hotspot is not annoying when pointing the lamp far (to about 45m) as I do. But it's not much of an improvement over the original Edelux, the light colour is a bit cooler, all in all, it's a good lamp, better than I expected, but barely better than the original Edelux.

New beamshots to come (I made beamshots but on a wet road, and they are not comparable to other beamshots).

2.v.15 Dynamo headlamp: Schmidt Edelux II, with IQ premium reflector, 2013

Tested: From 11 Dec. 2013. Sunup compatible: ?

I compared the Edelux II with the Saferide-60-neutral-white and the latest version of the Edelux and I'm disappointed. The Saferide-60-neutral-white is the best lamp except for riding through tight curves where the Edelux II lights up the road in the curve because of its wide beam, but weakly, too weak I think. The beam has 3 clear hotspots, which attract attention dus divert attention. Apart from those hotspots the beam is very weak. After making the beamshots on a damp road (to be remade) I made some rides switching multiple times between Edelux II and Saferide 60 neutral white, which confirmed that the Edelux II's beam may look good on long-exposure beamshots, but is not as good as the Saferide except for through corners. The LED light colour is a sterile cool white, inferior to the Saferide-60-neutral-white and inferior to the (greenish) colour of the Edelux too. Beamshots have been made, but on damp road so I will probably remake them (I will then place both on my site).

2.v.16 Dynamo headlamp: B&M Avy, 2014

Tested: From mid Nov 2014. Sunup compatible: ?

This lamp's beamshape reminds me of the Cyo R (Cyo 40). A similar main beam at the start with sharp corners close to the bike, becoming wider farther from the bike, but not the sharp far corners and with a brighter section at the end in the middle. B&M seems to have become an expert in making lamps with hotspots... I didn't like it, it is far inferior to e.g. the Pico 30 and H-diver.

More information: To come: Dynamo headlamp: B&M Avy

2.v.17 Dynamo headlamp: B&M Eyc, 2014

Tested: From mid Nov 2014. Sunup compatible: ?

This lamp's beam is as usual with B&M in cool white (bad choice), and the lamp badly overexposes the area near the bike, and even more on the fender where it overexposes enormously. The lamp has a section in the middle on the wall shot that is much stronger and a bit higher than to the sides, which means that when aiming the lamp you can easily aim it too high, such that opposing traffic gets blinded. This is something I already lamented about the LS 885, and it's beginning to be a real problem that people don't aim their headlamps correctly, blinding others. In beamshape this lamp and the Avy are far inferior to the Pico 30 and H-diver. In construction I like this lamp, it can be openend and thus repaired if spare parts are available or if there is some loose contact. On the 2nd ride my lamp died, I opened it up but saw no loose contact...

In use this is one of the worst bike lamps I tried in years, so not recommended.

2.v.18 Dynamo headlamp: Roxim D6, 2014

Tested: From 30 Nov. 2014. Sunup compatible: ?

This lamp surprised me in a good way. I tried it on still wet roads from rain, and I could see 50m far with it, incredible, but perhaps because of the light colour, I had seen the different light colour of the 2 LEDs to the side (I think they serve mainly as lights to be seen) which are bluish (cool white) and the LED in the centre for the main beam which is yellowish. Is it neutral white? It's definitely good, it works. This lamp is a relief after trying the B&M Avy and Eyc, which are just poor. It doesn't suffer from the issue of tending to aim it too high which happens with certain beamshapes. The light near the bike is a bit strange but perhaps useful in slow climbs? I will experiment with a shroud soon to limit light to the sides. The lamp needs to be mounted in a non-aerodynamical position, not as it is shown on the website! I don't understand why Roxim didn't reply to my email long ago, I quite like this lamp. It's not as big a beam as the Luxos, and of course it doesn't come close to the Saferide 80, but the beam is very good, and the main section is very smooth, no artefacts there, just near the front wheel. I will ride more with it on dry roads soon and compare with a few other headlamps.

2.v.19 Dynamo headlamp: Herrmans H-flow, 2015

Tested: From 19 Feb. 2015. Sunup compatible: ?

I don't like the output of this lamp. The lamp gives various patterns close to the bike, the beam itself is irregular with a hotspot and you can't see far with it. But I will compare it with the H-diver to give my verdict (as it's about the same price)...
