I bought a Lumina 850 on the basis of the advertised runtime of 1.5hrs at max 850 and around 4 hours for the mid setting and was very disappointed when it went off after 1 hr 45 mins and I’d been riding mainly on dip and the mid setting.

Anyone able to comment on what run times they achieve with their Niterider Lumina lights?

I have a 750. Not used them for a while, but pretty pleased with the run time as far as I can remember in night rides a few hours long.

I’ve owned two now. I found they never really ran as long as they said, and they all died after 18 months as well. The first one just stopped working and the warranty replacement would only work on the lowest power setting after a year.
