I answer here to a post from a different thread since it fits better here:

Thats a bummer with the formatting, here is a description to each images as shown in the
translated post/
original post: Outbound on High, Outbound on medium, outbound on low; SL-F dipped at 16W/1000lm, SL-F high beam at 16W/1300 lm, Sl-F dipped at 8W/650 lm, SL-F at Daylight mode; Ixon Space full power, Ixon Space medium, Ixon Space lowest.

It is really hard to recommend a light, since people have different tastes and needs. First of all, all lights will give you at least 50 m usable reach (in dipped beam mode), so all of those lights will do the job well for your described usage.
Hope the following helps you to pick the right light
if you want an integrated high beam in your lamp (the high beam in general gives you better view in curves when the bike is tilted while turning),
then the choice is only between the Lupine SL-F and the supernova M99 (Mini) Pro. The former has a much wider spread, the latter a narrower beam, bit warmer light color and a bit more punch/throw, albeit a much more inhomogeneous beam shape. Both lights give you in dipped mode at least 50m throw, the Supernova a few more meters. In the high beam mode, the throw of the supernova is distinctly better (+ 15 to 20 m) compared to the lupine. The battery version of the Supernova is ridiculously expensive, otherwise you can connect the ebike-version (mini pro 25+/45+) to a 11V battery pack (i wouldn't use the M99 Pro, that ione wastes 5 W for daylight running lights).
Also B&M recently released their IQ-XM, an e-bike light with integrated high beam function, which accepts any power source with any voltage from 8 to 48V. Haven't seen any real life beam shots yet, and the throw in low beam is probably weaker than that of the Ixon Space/IQ-XE (80 vs 150 lux). If there is not much oncoming traffic and you don't ride often in very wet conditions, it probably does as well a good job.
In case you do not need an high beam integrated in the lamp:
The throw of the ixon space will be a bit better (it has 150 lux at the brightest point) than that of the Outbound Road (with 115 lux at the brightest point). The Outbound has a wider beam, especially in front of the bike, which comes handy at turns. Advantage of the Outbound: the rubber mount can be easily adjusted while riding, which allows to turn the light a bit up to have higher reach if there is no oncoming traffic. This adjustment is nicely shown in a video from the manufacturer, where you also see the afore mentioned/critized bright spot (which is
discussed here by me) that gets weaker/stronger depending on the mounting position : youtube.com/watch?v=8hnms2k7Ti0&t=7m42s. The OL is albeit adjustable still mounted securely when driving over potholes (see for proof that crazy video: youtube.com/watch?v=28HbGpL5EIY&t=3m10s). The holder of the ixon space cannot be moved -by design, it can only be moved if you mount it a tiny bit loose.
Another option would be a supernova light without high beam, then the m99 mini pure 45 would have the best throw (at the cost of a slightly inhomogeneous beam shape).Should you not like the self contained style of the ixon space, you could get the B&M IQ-XE (same light, just for e-bikes) and connect it to any 6-48V batter)
Finally beam shots and videos, some of them in german:
Here is a
wall shot of the ixon space, here the beam of the ixon space on a
wet pathway.
Here is a
wall shot of the Outbound Road vs the Ixon IQ
Here is a wall shot comparison of the Ixon Space/IQ-XE with the Lupine SL (identical dipped beam as the SL-F): youtube.com/watch?v=VZhVJPwdZD4&t=10m30s, first the SL is shown, then the IQ-XE/ixon space),
and here is a nice video showing the ixon space (markings in the middle at 50m, last at 100m: youtube.com/watch?v=oWbk9mPQuSg&t=10m35s
Here is
a beam shot comparison between the Lupine SL-F and a Supernova M99 Mini Pro 25+, and here is the
(translated) explanation to that beam shot. (download the images in the highest quality and watch them in full screen mode...
Here is a
very good review on the Supernova M99 Mini Pro 25)
and here is
list of beam shots of the SL-F
The Ixon Space is shipped i.e.
by bike24 to the US (some others do as well, others like bike-discount.de don't)
