Why Gaciron Cetus-1700 Is a Serious Light for Serious Riders

When you ride long distances—or hit the trails after dark—you need a light that’s more than just bright. You need a tool. The Gaciron Cetus-1700 is exactly that.

With a max output of 1700 lumens, dual-beam design, and intelligent light sensor, this light adapts to your environment instead of overwhelming it. The beam is strong enough for technical descents but focused enough for urban riding.

Its under-handlebar mounting (with the H17 bracket) lowers your center of gravity and eliminates glare on bike computers. USB-C charging and IPX6 waterproofing round out a product clearly built for serious cyclists who ride in all conditions.

Bottom line: it’s not just a light, it’s your nighttime riding system.
