I am with MRMO
i think the answer is why you ride at night. Do you ride at night to ride at night in which case a little less light isn’t an issue. Or do you ride at night because you have no choice, your ride at night to train during the winter, in which case more light means you can go faster.
…with 3-kids I do most of my riding at night, over the hills and in the woods locally, therefore good (bright) lights equals more speed equals more fun!
I recently changed my c1800 lumen HID for an 1700lumen (approx) Troute Liberator 3.0. I have more than enough light now for my purposes and through the Liberator now have a controllable light with up to 12-hrs from the battery (my HID would give 2.5hrs tops).
I like Troute’s new prototype, pushing boundaries – but I doubt I’ll personally ever look for more than 2000 lumens – my focus is on battery life and durability.
