The new Clearwater Shelby bike light is durable and has five light modes: High, Med, Low, Extreme Low and Strobe. Pressing the on/off button toggles through each of the modes. The Strobe mode is for daytime conspicuity, to activate the "Flash" mode simply press the button 2 times quickly. To turn off the light, press and hold the button for 2 seconds.
1- High mode: 900 lumens, @ 3h 40m ~ 4h
2- Med mode: 450 lumens, @ 7h 30m ~ 8h
3- Low mode: 225 lumens, @ 15h
4- Extreme Low mode: 100 lumens, @ 33h
Don't look directly into this light while on High. The High mode is really bright! It is best to reserve the High beam setting for use while on the move or with some wind, as the housing can get quite warm to the touch and the moving air helps cool the light. When in a stationary position, try using one of the lower power settings. They are still quite bright!
