I am thrilled with how bright this light is. LED technology has come so far and become so inexpensive. I can remember when 150 lumens was really bright for a HEADLIGHT! The lane markers are great, too. Run-time is ample for my 5 mi. commute. Seems to recharge very quickly.
I use it for night riding mostly. Also day riding for safety from 4 wheelers. It has other options like flashlight This is a great light for all occasions.
I bought this light along with the K-edge Garmin combo mount. I can connect the light when I need it. The Urban 800 attaches under the mount, so my handle bars stay neat and sleek.
