I had something like this — from Craftsman, I believe — quite some time back and eventually stopped using them because they were so heavy that they eventually hurt my head.  Sadly, I’ve never looked back at this kind of thing since — which means I missed the LED revolution.  These look a lot lighter and more realistic to use.  Looks like it’s time to give them another try.

The ones pictured are from Panthervision and list for $23.

  1. Note that because these are basically a couple of Photon-style key-ring lights, their battery life will not be great. They use the fatter CR2032 coin cells instead of the mere CR2016s in most Photon-type lights, but those cells still only have 150mAh capacity at a rated current of nought point one milliamps.

    When fresh, the batteries will have to provide a few HUNDRED times as much current as they’re rated for, so they’ll sag pretty quickly, and so will the light output.

    It’s amazing how well coin cells last in LED lights, because the LEDs still work dimly even when the batteries are nearly dead, but you still shouldn’t expect “full brightness” operation for more than, oh, ten minutes or so. How long the brightness will be acceptable to you varies with the job, of course, but I’d be surprised if anybody was happy with the output after more than one straight hour of use. It’d be better than nothing for several hours, but not nearly as helpful as clamping a regular small flashlight in your teeth while you worked.

    These really do look like a good product for the money compared with the old 4-AA-battery version with two normal penlight bulbs, but if you want long use, be ready to hack in a headband battery pack or something.

    It’s not like a single AAA on each side would make them too heavy, either. I’ve been delighted with the Fluke LVD1 light that powers itself from one such cell, and it’s quite at home rubber-banded to a glasses frame. I use it clipped to my hat brim more often, though.

    I’ve really made a conscious effort not to buy things that’re powered by lithium coin or alkaline button cells. It’s not just that they’re expensive to feed, but the low capacity virtually guarantees that they’ll run down in the middle of something important. And unlike rechargeables that you can “top off”, with single-use cells you either go into a project with partly-dead batteries, or replace them and throw out partly-good ones.

    Screw that. My laser pointer is a 1997 Radio Shack model that takes 2x AAA, and I have a set of Renewal alkalines in there that I charge every year whether they need it or not. My every-day-carry flashlights are AA-powered. The only coin-cell-driven light I use on a regular basis is the Princeton Pilot clipped to my laptop’s strap. It’s ridiculously handy but I only use it for a moment at a time, so I haven’t run the factory batteries out yet. If there were rechargeable 2016s or 2032s…

    Whoah, stop the presses! A quick search reveals Batteryspace.com selling “Li-ion rechargeable 2032 cells”. This pleases and excites me. 🙂 Gee, I wonder who might consider reviewing such a product…

    Just looking at the comments about the lighted glasses and I have to agree that the coin cells are really the weak point of these glasses, but the concept is a good one – so much so that I patented my own version of Illuminated safety & work glasses, patent 6,824,265. My latest prototype uses 2 AAA rechargeable Li-ion batteries that weigh an incredibly light 7 grams each – not easy to find, though. I had to go to China to get these batteries! However, the glasses are light (2/3 oz) even for prototypes and the batteries power 6 hb leds full power for an average shift. The glasses are so bright that they have tested successfully in underground coal mines and other occupations where lighting is absolutely necessary. And I will not have to buy expensive coin cells…that is really the biggest drawback using coin cells.
