Similar and higher output version of the Seemee 100, the Seemee 180 bike safety light is designed for urban, road, and commuter cyclists.
Transparent optical fibers allows for 180 lumens of red light to to be visible from over 2 miles away at an angle of 260 degrees. The Seemee 100 offers 3 brightness modes at 125, 63, 27 lumens, and 3 flash patterns with max output at around 125 lumens. The 180 lumen output is triggered by brake flash mode.
The Seemee 180 bike rear light also come equipped with an optional brake sensor, on sudden change of speed, a constant beam of 180 lumens will be triggered offering temporarily enhanced visibility, very useful on the road or busy city streets, though for riding on gravel roads or mountain trails, this mode can be turned off to conserve power. Built in infrared sensor automaticaly dials the output to day and night mode depending on the level of ambient light detected. When power drains to around 5%, the low power economy flash mode will be triggered at 27 lumens max, this mode will help get you home and is expected to last up to 20 minutes. Max runtime for Seemee 180 bike safety light is measured to be 1.5 hours to a max of 18 hours on lowest brightnest setting. Note this is tested and measured without frequent activation of the brake sensor.
The Seemee 180 bike tail light comes with several mounting options. It uses a smaller but similar mechansim as the Garmin quarter turn mechanism. Compatible with most seatposts, even saddlebags, helmets and backpacks. Weatherproof at IPX6 and conveniently USB rechargeable.
