Worth it!!

By: on 15 May 2023
I recently bought a cheap bike headlight which claimed 600 lumens (may be true) but was a spotlight and pretty useless. I therefore paid realised I needed a proper light and bought this. It's epic! My commute takes me though a windy and hilly narrow path in a pitch-black wooded park and it gives all the light I need, so much so that I ride faster at night than during the day. The flash function is great too - super bright for day time, so I use this for extra protection at intersections during the day also. No one hasn't seem me yet! I still use the cheapo bike light I got too, but mount this to my helmet as the spotlight is great for pointing it directly at drivers' faces to really make sure they've seen me.

Great all-rounder light

This is now my third Lezyne light, also had the 1500lm and 1600lm models. I do a lot of long audax rides which require night riding, and I find I can get 8-10 hours from this light on the economy (250lm) setting, which is fine for riding on flat or uphill in the dark, and the high beam setting for descents is like daylight it's so bright. Rubber clamp is easy to take on and off handlebars.

Best light I have owned

The Lezyne 1800i is the best light I have ever used. It's brightness & the wide beam gives you great depth perception in the dark. Listed run time on 1800 lumens ( overdrive mode ) is true at 1 Hour 40 mins plus & worth every cent for your own safety.
