(Update 4/20/2014: See my comparison of the Cygolite Expilion 250 with the new Cygolite Expilion 800!)
As I explained in a previous post about bicycle lights, for several years I put up with the hassles of heavy bike lights with separate water bottle batteries, or running multiple self-contained LED lights that would quickly drain AA batteries. Now the Holy Grail of commuting bicycle lights has arrived: the new for 2011 Cygolite Expilion 250!
Why is it the Holy Grail of commuting bike lights? It is the one light that has all of these features I’ve been wanting for years:
- A bike light taking advantage of latest LED improvements, rather than lagging behind a few years
- Wide enough beam pattern for commuting but with no dim spots
- Bright enough for the 30 mph downhill portions of my bike commute
- Small, lightweight single piece unit that doesn’t take up too much handlebar real estate
- Easily removed from the bike for security reasons or for ease of recharging
- Decent run time (3 hours) at maximum brightness
- Rechargeable battery with short recharging time (5 hours max)
- Standard cable for recharging (in this case, USB), so I can charge at home or work
- Sturdy aluminum rather than plastic mounting bracket
- Easy availability of spare parts/brackets
- Reasonably priced ($139, I got it for $124 with some other discounts)
While I still have to take it out on a commute, I took it out for a spin tonight and the single Expilion 250 was easily brighter than the two Cateye HL-EL530 lights I had been running together – even after my homebrew LED upgrade of those Cateye lights!
The only thing that jumps out at me as a “dislike” is the rubber cover which is hard to push in to the USB charging port in the back. Luckily I can leave it out most of the time and only have to deal with it on rainy days (unusual here for Southern California).
Also, there had been reports of tight mounting bracket issues, but I didn’t have any problems with mine, and according to Cygolite the issue has been resolved with bracket replacements to those affected.
I will still use the Cateye HL-EL530 lights as backup/”be seen” lights, on my other bikes and on my commute bike in case I forget to recharge the Expilion – but the Expilion will likely be the “light of choice” for the commute!

See how small it is.
