Princeton Tec Push: Well Lit

My what bright eyes you have on your bike with a new handlebar-mounted LED from Princeton Tec. We weren’t able to out ride this light on the commute home. It throws a nice oval-shaped spot in front of you.

The decorative blinky LEDS on the side, don’t do much, but look cool. It also matches our cooktop!

Princeton Tec Push: Matches Cooktop

Wouldn’t want a kid to blind themselves, but you could slide this light out of the clamp, hand it to a toddler, and tell him it was a light saber.

It looks sci-fi.

Our commutes are in the city with street lights, so we’re not heading into the heart of darkness or we’d need more lumens. Speaking of that, what’s your light setup this year?


  • Power: 100 lumens
  • Lamp: max bright led
  • Burn time: 63 hours
  • Batteries: 3 aaa alkaline or rechargable
  • Weight: 115 grams

MSRP is $49.99 and the well-designed clamp means it won’t rattle over rough pavement.

$50 for 100 lumens is pretty good.

As for the heart of darkness rides, 300 is my minimum requirement.  But my light doesn’t match my cooktop!

I’ll be a contrarian and argue that more lumens isn’t always better - especially when it’s really dark. I’ve used HID lights but strongly prefer my dynamo powered B&M IQ Cyo. The problem with super bright lights is that the difference between the area being illuminated and everything else is so great that your eyes can ONLY see what the light is shining on. It creates a sort of tunnel vision effect. With my less powerful Cyo I can more than just what the spot of light is illuminating and I feel safer descending the road down to Golden Gardens with this set up than with my older, brighter HID light. Of course the other advantage of the Cyo (and other dynamo lights) is you never need to charge it and never need to worry about the battery going dead.

That’s why I asked readers to respond—we’re not commuting in real darkness and I’ve experienced the tunnel vision for sure when I have. Also, of course, getting blinded by someone bright enough to be seen from space.

200 lumens on the helmet, 300 (dual LED) on the bar.  200 wasn’t enough on the BPA trail evening commutes last winter, so I added the 300 on the bar. The trail is away from any streetlights, and can get ‘heart-of-darkness’ dark. I encounter pedestrians wearing stealth black fleece and need all the light I can afford.  Both units are Li-ion powered LED’s, so total wt. is about 350g for the pair.

Is it possible to mount this lamp on a helmet?
I’d like to have a bright flasher up high where it will be seen by drivers in trucks.

There seems to be an issue with some of these where the metal head piece connects with the plastic body breaking. I wouldn’t be surprised if there was a recall in the future. The EOS however is the best battery powered light for under a hundred bucks in my opinion.

Am I the only one tired of LED lights with 3 batteries?
I get the 4 volt thing, but every single battery charger I own or have ever seen can only charge batteries in pairs.

There is a reason why hot dogs don’t come in packs of 3.

Did notice that when I opened the battery compartment, the two pieces released explosively. That’s what caused [the scratches]( in this photo.

Thought the same thing yes or why it didn’t have those round batteries.

I, too, have the odd-numbered AA/AAA battery problem.  I recently purchased this charger that takes care of the problem. EcoVelo recommended it.  It’s basically 8 individual chargers that all work at the same time.  You have to be careful about mixing different capacities to some degree, though.  This retailer (also recommended by EcoVelo) has a good supply of low-discharge nimh batteries as well.
