Why do you think you need around 1000 lumen’s??
If the beam angles are correct, then 500-600 would be more than enough.
Remember, its not always the more the better.
I have (sell) a couple of wee adjustable beam (zoom) lights that are around 150 lumen’s each, and because you can get the beam angle spot on, one on the bar and one on the helmet would be enough for most riding.
Its all about mine is bigger than yours in anything over 700 lumen’s in my opinion!
Having said that, there is nothing wrong with having silly bright lights, but if you’re looking for longer runtimes, then you could easily get by on less output.
