After reading a detailed review, here’s a breakdown of the CETUS-1700’s strengths and possible limitations:
✅ Pros
• Brightness & coverage: 1700 lumens with wide beam coverage.
• Anti-glare cutoff: clear beam separation reduces dazzling.
• Underneath mounting: saves cockpit space, keeps beam path optimal.
• Smart on/off: light shuts off after being idle, reactivates when moving.
• Good battery life: lasts long on eco modes.⚠️ Things to consider
• On Turbo mode, runtime is limited — need to manage modes wisely.
• Underneath mounting may require compatibility checks with certain mounts.
• IPX6 waterproofing is strong, but extreme conditions still require care.Overall, it’s a great upgrade for night riders who want a mix of performance and smart design.
