What's your lighting strategy for multi-day, unsupported adventure racing (i.e., no guarantee you'll be able to recharge during the race)? How many milliamp hours of battery capacity do you expect to burn through in a night of racing? How many lumens do you typically use while trekking on trails? While riding? Apart from obvious things like price, weight, runtime, and maximum illumination, what factors (adjustable light levels, spot/flood beam pattern, no hotspot, color temperature, form factor, battery type, etc) do you find important in a lighting system for expedition AR?

For MTB, I use Exposure Lights which are great. They are cable free lights. I use a helmet mounted "Joystick" (https://exposurelights.com/bike/front-lights/joyst...) together with a handlebar mounted "Maxx D"
(https://exposurelights.com/bike/front-lights/maxx-...). I use both on low power (last 24 hrs) but may increase to medium setting for short technical sections (last 10 hrs). When I put the bike back in the box, I recharge them using the piggy back cells (https://exposurelights.com/bike/batteries-and-char... and https://exposurelights.com/bike/batteries-and-char...). The piggy back cells have sufficient charge for multiple charges.

Check out Glowworm lights too. https://www.glowormlites.co.nz
You can program different brightness levels, for very long burns on low while trekking to fry-chicken for fast bike descents.

They have charts on their site for burn times.
With good management, a single 2-cell battery will do a night for trekking and AR -speed biking. You can get them up to 3400 maH now quite cheaply.
I like to have at least 2 lights while biking, with one just on low or backup.
