If winning the World 24 Hour Time Trial Championship meets your
standards, then Oculus is the undisputed World's Fastest Bike
Light. I also had three of the top ten, a handful of age group
winners, and three of the seven front row starters too, The new
world champion, Martin Bendszus, from Germany, and most others
used a power and brightness combination that gave them ~500
lumens for 6+ hours on the brand new Oculus 3000Extreme. Some
earlier Oculus customers used a 10 hour or 5 hour setting on
their Oculus 1800Ultra. Interestingly, a few racers introduced
themselves as original Kickstarter backers, still loving their
lights. Martin covered 514.8 miles at 21.6mph average for 23
hours 56 minutes.



I wonder how one does that at his age. If I try to hold such an average
for just half an hour my tongue is on the handlebar.


... An early hours surge in daylight by one
conventional and one recumbent rider left Martin in third place
by about 20 minutes. After full darkness took hold, Martin
gained time each lap til he took the lead around 3:00AM, ...



Probably the light melted the air molecules in front of his bike :-)


... and held
on through the daylight for the win. Second place was 510 miles
in 23 hours 50 minutes at 21.4mph, less than three miles back.
That's an average difference of only 220 yards per hour over 24
hours. Oculus was the official onsite lighting sales and support
for the World Championships. As a result of the event and glowing
praise from an increasing number of well known distance racers
and RAAM winners, Oculus will be the official headlight of RAAM
and its related races for 2018.


My goodness. If you ride slowly like us older chaps you can install
a Oculas and you probably won't even need to pedal any more. Just
turn the light on and away you'll go. :-) -- Cheers,

Photon emission propulsion? Oculus beam will let you use much lower
brightnesses when moving slower, for previously unattainable burn
times at any given brightness level.


Most lights can do that. On my MTB I can curb power to 40% and and 20%
for slower stretches. On the road bike only to 40%, the 20% setting is
used to blink mode which I don't use except for emergency. On the road
bike 100% light power which draws about 8W from the battery provides
4-5h ride time. 40% provides light for twice that time but by then my
behind would hurt so badly that I'd long since have stopped riding.
