Great light
I primarily use the light for commuting. I’ve used it in the rain and it it did not have any issues. The light is heavier than my older 1,000 lumen light by a different brand, but this Lezyne light is much brighter with a longer battery life. The helmet mount has kept the light secure so far with no rattling on rough roads. I also have a Lezyne light mounted on my handle bar (1800 lumen). With the various brightness levels on both lights, I have no problem seeing the road regardless of the weather.
