Cygolite Expilion 350 – 2012 Mtbr Lights Shootout

Lights Shootout

We’ve never really tested any Cygolite products before and it is perhaps the most requested (by readers) addtion to our Lights Shootouts. Cygolite finally obliged to request and they sent us the Expilion 350 and the Mitycross 750. We were giddy with excitement to finally experience one of the top selling lights in the market.

The packaging stands out as one of the best in class. It is compact and very professional. As you can see in the photos, everything is neatly organized and the box contains many of of the specs and important information.

The light itself looks great with excellent materials and quality of construction. The light head has a big head and heatsink to dissipate heat. The switch is big and raised but is not illuminated perhaps to avoid distracting the rider.  The back of the light has a battery that can be removed and replaced without tools. The battery is a standard lithium 18650 but in a proprietary plastic holder so spare batteries need to be purchased from Cygolite.

The light has 4 light levels and a flash mode. Switching the light on puts it on Med-high, Medium, Low, High, and Flash mode.  It is odd and non-intuitive that the light does not switch on High mode since that is what the user usually wants.  As a result, the user has to scroll through the light levels just to get to High. Also, the very annoying Flash/strobe mode comes right after high so most users will always get to it even though they do not want it as they try to find their light level.   Too turn the light off, the button is pressed longer than two seconds and the light fades to off nicely.


  • Price: $110.00
  • Claimed Lumens:350 Lumens
  • Light Head Weight: 133 grams
  • Installed Weight: 161.5 grams
  • Run Time: 2 hours
  • Measured MTBR Lux: 31 Lux


Mounting is perhaps the best in class for the self-contained lights in this shootout. It has a very high quality mount that can take both bar sizes and it is screwed in to place with a handy thumbscrew. The light can be aimed left to right easily and the tension can be adjusted.  There is also an available helmet mount not included in this kit but included in the Expilion 400.

    I love this light for everything! It fits perfectly in the center vent of a Giro Altus helmet, just put a strap around it and go. For commuting, you don’t need a brighter light and for offroad, I have yet to make it go dim. I use the med-high and have ridden 4hrs with no problems. Superlight and overbuilt, need I say more?
