With a 1 watt LED and a fairly well controlled beam pattern the Nano 1 is a light you can ride with at reasonable speeds.
It's not too visible at obtuse angles so is worth supplementing with a secondary light for visibility.
The all alloy construction is top quality though, and the sealing first rate. The rear light is excellent. Similar in design to the Nite Rider TL5.0, it is a seven-LED unit with a lens that lights up, rather than focuses the light. The rear mount requires a flat blade screwdriver for fitting, and the front is toolless.
For the money, this is a nice balance of lighting, edged out by the Nite Rider Ultrafazer and Blackburn Quadrant/Mars 3.0 combo packs.
