The Pulsar 1 is a colorful and compact, super bright single LED keychain light made by Princeton Tec.
It comes in a variety of LED colors and features a transluscent body that also comes in a variety of colors such as lime green, fire engine red, and cobalt blue.
Power is provided by either a single CR2032 or two CR2016 lithium coin cells, depending on the LED color.

The Pulsar 1 is ready to use as soon as you open the pack. You will probably want to attach the split ring to the slot at the rear of the light first though, as the flashlight is
tiny and can be easily lost or misplaced. That's a bit less likely to happen if you put it on your keys right away. The split ring is a bit difficult to get on, but can be done
with the aid of a small screwdriver or a dull butterknife and a few moments of patience.
To use the Pulsar, just give it a squeeze. As long as you squeeze, it stays lit. Stop squeezing, and it goes out.

Depending on the LED color, the Pulsar uses either a single CR2032 cell or a pair of CR2016 lithium coin cells.
To change the batteries, insert a small flat bladed screwdriver or a butterknife into the slot you'll find near the keyring, and gently pry the flashlight halves apart.
Note the position of the old batteries first, then slide them out. Install the new batteries the same way. The button (-) side of the battery faces the LED lead that has the
small insulator on it.
This picture should help clarify things.
Once you have the new battery or batteries in place, just snap the case halves back together.
Total battery life should be in the 10-15 hour range with intermittent use; with the brightest light being within the first half hour or so.
This is typical for *any* light using this size and type of battery.
Durability testing to commence shortly

TEST NOTES:
Samples provided by AlphaNet.
Both units were received together a short time ago, and will be tested together. Optical tests first, then physical & durability assessment.
There has been one instance that I'm aware of where the case halves have seperated while the light was on a keyring; its owner came home and discovered all the "guts" were
missing and only the two halves of the shell remained. I will be looking especially closely for this type of failure to be sure it was just a rare fluke like I think it was.
