[quote=“Rivendell Bikes”]This is the best cheap bike light we’ve seen, and we’d put it up against anything in its price range (it costs $45). Here’s the nuts and bolts followed by our more subjective evaluation based on use.
Fifty lumens. Most lights these days are rated in lumens, and fifty is bright enough to light up a hillside 130 yards away. We’ve done it, and we did it with this light.
Three AAA batteries (included). Replacements available anywhere.
Three modes, plus flashing. Bright for riding unlit roads, med for lit roads, low for reading, flashing for when you need to attract attention. Let’s say you get lost, and the chopper is looking for you…
Here’s the best part: It comes with----
a bar mount
a helmet mount (you can also just use the forehead mount below)
a forehead mount
three AAA batteries
For commuting, the bar mount is fine, but for night riding on twisty roads and trails, use one of the head mounts so you can aim it around corners before you get there.
The beam is wide enough and even. No problem night riding through brushy forests and bumpy trails. I did that two nights ago and will do it again tomorrow night (October 21).
The click-on button is easy and unlike so many lights I’ve used in the past, won’t go on if you pack it into a pocket with some other stuff and ride over bumps. The EOS bike light won’t go on unless you yourself poke the rubbery button with some fingernail-bending force.
It mounts without tools, it comes with batteries, and as lights go, it really can’t get any easier than this.
Plus it’s made in the U.S.A. by Princeton Tec. A MUSA light!
As battery-operated smallish LED lights go, this is as good as they get.
Burn times with alkaline batteries (lithium batteries burn at least half again as long):
high - 113 hours
medium - 115 hours
low - 121 hours
flashing - 115 hours[/quote]
I sent an e-mail to Princeton, just checking to see who is interested in this light.
