This one gives you max 900 lumens brightness under 4k.
3 brightness modes and the flash mode helps early morning rides
Product quanliy is wonderful and deliver in said time. I am using it for long now and no complain
Lighting options are very good. Charging while lighting option is the missing.
Light output is sufficient for night rides. However the handle bar mounting system has a flaw in design. Some vibration on the road and the light falls off the bike. There are 2 tabs on the mount which gets locked in to the light. The release handle vibrates on bumpy surfaces and the light falls off. Happened twice for me and was fortunate that someone riding behind picked it up and gave it to me.
Light Build - 5/5
Mount - 4/5 (clip gets easily detached, on rough patches light may come loose & fall)
Brightness - 5/5
Battery backup - 3/5 (runs out pretty quickly on high mode, medium mode is perfect. Not for bikepacking trips)
Charging - 3/5 (doesn't support fast charging, will take some time, so, plan ahead)
Reliability - 5/5 (never failed on me)
Versatility - 4/5 (is a bit bulky but pretty small in size)
