I've recently picked one up and when fully charged the light seems to only display "1.0" hours left when on full beam mode. It's supposed to be 1.4 hours on max. Is that the same for everyone else?
Obviously the indicted time isn't what's actually important, but I've yet to do a long enough test to measure actual runtime.
Originally I thought the display must just round-down to the nearest 0.5, but did notice that it later on displays 0.8 etc.
Mines always been 1.0 on full beam with a full charge.
I no longer have this light (I’ve replaced it with the PR2400) and from memory I think it rounds to the nearest 0.5 until it gets to 1.0. Then below that it rounds to the nearest 0.1.
One thing I like about the PR2400 is the better display showing hours and minutes remaining.

Running at full chat (1,600 lumens) for 1 hour 35 minutes during our test, the Ravemen lasted 11 minutes longer than its claimed run time.
Give it a test ride at full beam.
Mine also shows 1.0 at full power. Never tested the run time for this though as I use the low beam mostly, as it’s on my gravel bike.
Tried mine last night on a ride and yeah full beam gives a display reading of 1.0
I never run mine in that mode though so can't comment on how accurate it is. I normally use it on dipped beam only on road, on the 2nd power setting.
I have the PR1200 which I believe has the same display, just has a less powerful main beam. I've used mine loads at full beam on the Downs. After about an hour of full beam and varied dipped beam use on the roads home, mine showed 0.6 on full beam or 7.5 on the lowest setting in dipped so it definitely rounds to the nearest 0.1.
