I have the Contrail and Moment DW. I like both. The Contrail (now Pretrial) packs a bit smaller, and is a bit lighter, but the Moment is really easy to pitch, especially after a long day.

The Diablo is a fantastic light. A bit heavier than their other options they show for head mounting.
Learn to switch the program modes. I think I have mine on 3, gives me a long long time on low (perfect for a camp light...).

I use it often on the bars with the bar mount when I'm not on the dyno equipped bike. Plenty of burn time for my local loop riding on medium, and I can switch to high as needed.


Also, this thing is silly looking as hell:

I don't run it when I wear the light on my head, but I had to emergency zip tie that light on for that trip, so my camp light stayed on the helmet.
Really diffuses the light. Pick one up if you camp. Hung from the tent, bars, tree branch, etc. it really lights up camp. Here I'm making use of it to finish cleaning up the yard:

Exposure Diablo on the head. Recharge as needed from the dyno or wall.
Usually set on low.

I also have a Fenix UC40 UE. On medium or low. Runs on internal rechargeable battery or you can put in the 18650s or CR123 I think.

I have used many PB superflash lights. All secure. And I have never had an issue rotating enough to get them to release.

Attachment...
Left the proper fitment for my Exposure on the bench, improvised when it started getting dark. Zip ties in the tool kit always!

(also sort of weird that I threw in my Leatherman AND its case... that ended up being fortunate...)

I'll be giving my Black Diamond Mega mid a try this winter. Just the mid, no netting, etc.

I've slept in my 30°F bag into the 20s without a tent. And I've slept in my 0°F bag in my Tarpent Moment DW down into the teens. I have also made a hammock work into the 30s with a 30°F bag and pad.

The tent can add a bit of microclimate around you, but getting out of the wind and protecting yourself from rain / frost / snow would be its primary function. Most '3' season tents can be used into 4 seasons assuming that you don't get a foot of snow and collapse the tent.

A friend used this mount on the front of Jones bars for his Luxos U:

If your aerobars have a bridge I bet you could mount it there with some shims.

Run the extrex on AAs. It lasts a long time like that and you can carry spares.
Use the dyno light at night as needed. During the day charge up your secondary light and your phone as needed. Leave the phone off or in airplane mode until needed. It will last a long time like that.

If you aren't charging and it isn't raining (downpour - drizzle OK) you can run the etrex from the dyno while moving. As soon as you slow it will switch over to internals. There is a setting to change the power notification... But I forget where it is.


Luxos U is a great light. I have one on my road / gravel rig mounted on a Marks rack. I wouldn't run one on my bikepacking rig. For that I have an exposure Revo and a USBWerk (sine wave could work for charging too).

You can run the Luxos U as a daytime light (it switches to lower power in the daylight) and charge at the same time - but you need to be moving pretty good - 14mph or more (could be 16 or 18). No way to do that at night. You can do it with standalone lights and a Sinewave or a USBWerk but you really split the power between lights and charge. No way around that.

Or, for no cost at all (seeing as how I have all these damn parts already), I could take the seat post rack from the Moots design, tuck it under and loop it through the bungee cords on bottom of the PR bag, maybe bend it a little bit, and *pretty much* have a Mr. Fusion.  I just took a much more expensive way to get there, seeing as how there was no such thing as a PR Mr. Fusion on the market when I started acquiring bags 5-6 years ago.

Thanks for helping clarify, though, bmike-vt.

I am planning to do similar with my Revelate... I just need to buy a seat post collar with the rack mount on it. I have spare tubing from other projects that I can use as stiffeners...

Not trying to drag up old drama in this thread, but Moots has been doing this design for years now on a more commuter-based look.  I'm not saying PR ripped-off Moots, but I had this system from them, probably 5 years ago at least.  Oh, and it never swayed.

Just an FYI:

The Tailgator costs $165... Carries 400 cubic inches (~6.5 liters) and is limited to 5 lbs.
I don't believe its waterproof.
It works well for randonneuring (have known some forum peeps who like it for that purpose...)
And it really looks like a take off on the seatpost mounted rack system. The internal rack is doing the work here, cantilevered off the seatpost.

For $185 you can get the PR Mr. Fusion.
Holds 6-13 liters, comes with a waterproof bag, in your choice of fabric and color.
The PR concept is really about stability, not load holding.
The weight is held primarily by the strapping through the saddle rails, and stability is gained by the internal mini frame.
I'm sure the triangulation to the seatpost adds a bit of weight capacity... but unlike the moots, if the rack on the PR failed somehow you would still be riding...

Wonderful pictures and a great landscape.

Happy with my Shimano hub and Exposure Revo. Using a USBwerk to charge. Made my own 3D printed switch housing that mounts to my steerer tube. I've been using a SON on my rando bike since lights were old school bulbs that would blow and you could only run 1 when climbing really slow. The new LED stuff is excellent in comparison.

That other linked thread is probably the best stating point / resource.

I really like the magnetic reed switches on the Edeluxe lights. You can pull the whole  'switch' right off and clean everything and then pop it back on. All sealed to the weather.

Yeah, very cool retro looking switch! Blends right in too. That switch makes me realize how easy it might be to design and print something with 3D printer system. Print up the plastic, insert three brass contacts and a rotating swiper...

Hmmmmmmmm. 

I've been riding with both for over a year. The Revo is (IMO) a better light for gravel / forest roads / single track. The Luxos can work, but it does have a cutoff beam per the German standards for traffic.

I really like this switch... but it is only 'on/off' - I know the maker and he may do a 3 position in the future...

I have the Luxos U on my rando / road, gravel bike. So far no issues in the rain and yuck... but that bike doesn't see as much use anymore - the Krampus is just so fun...

The early versions had a problem with water at the switch due to being able to unplug / plug in the USB wire / dongle.
The new version - the one I have - is all sealed - the dongle / wire is attached to the switch so you can't take it apart.
A friend had one on his ECR and he loved it. He did quite a bit of road / gravel on it as well as bikepacking.
Lots of rando guys and gals use them in all weather. They don't quite get the abuse that a MTB would see... but they still get wet.
