Princeton Tec Sync

By: Lisa Maloney on July 14, 2017

Bottom Line The 150-lumen Princeton Tec Sync is small, compact and comfortable to wear at a run. Instead of a button, it uses a dial selector to switch between lighting modes, which include a red light mode for preserving night vision and a lockout mode to prevent accidental battery drain.
  • Small and light
  • Simple, intuitive controls
  • Doesn't bounce as you run
  • Long battery life
