  2. Bright
    Like that it brightens the road and surrounds without blinding oncoming pedestrians/joggers/cyclists. The RN400 feels well constructed and made. The entire shell is aluminium that will help cool the light as well. And using a USB C port, helps future proof it too as the higher power means faster charging times.
