My New Helmet Light




LED headlights are getting better all the time. This little guy is a one Watt Luxeon LED with very good power regulation. Regulation means that the light gets the most from a set of batteries and keeps the light at a given brightness instead of dimming as the batteries weaken. The Princeton Tec EOS has three brightness settings and a flash mode. I actually find the flash mode to be too slow to be useful on the bike and it flashes at full power but these are minor nits. I'd also prefer if the light used AA instead of AAA cells. So I guess there are two things I don't like about this light.

But the positives far outweigh the negatives. The light is small and is supposed to be waterproof to one meter. (I don't ride under water so I haven't tested that feature!) It's easy to operate and the batteries are easy to change. The light pattern seems to be just right for my riding. I use this light on my helmet but it also comes with a handlebar mount. I run the light at the lowest power setting most of the time and that's fine for reading my bike computer or cue sheets. The middle setting is better for general riding, spotting road signs and potholes and things like that. At the highest setting, you get the brightest beam but of course that eats through the batteries quicker.

I'm pretty sure the circuit in this light was designed by Willie Hunt, a real guru in bike lighting circles. And yes, I'm enough of a nerd that I actually keep track of things like that. Anyhow, the Princeton Tec EOS is my latest favorite bike toy.

The link at the top of this post will take you to Amazon and they have a good deal on this light now. In the interest of full disclosure, you should know that if you buy the light via the link, I get a little kick-back from Amazon. This internet stuff is wild. In the old days I'd just tell my buddies about stuff and that would be it. Now there are actually micro-revenue streams. But I really do like this light and I'm not writing about it because of the kick-back. I'm writing about it because it is a cool light (in a bike-nerdy sort of way!)

Keep 'em rolling,

Kent
