The Swiss+Tech Micro-Light is a small, keychain light that uses a 5mm white LED, and a pair of CR2016 cells to power it. The light has a squeeze-only switch and a constant-on switch, and it comes equipped with a pair of split-rings so you can attach it to your keychain.

The continuous switch in my sample does not function correctly; which I'll try to fix when I open the unit for a battery change.


The Swiss+Tech is ready to use as soon as you remove it from its retail package. Slitting down one side of the package with a knife was sufficient to remove the flashlight and the retail card - which contains warranty information and battery changing information inside.

Squeeze the center of the Swiss+Tech to activate in momentary mode; release to shut the flashlight back off.

For continuous (hands-free) use, slide the small switch on the top of the flashlight back (toward the tail) until it clicks to turn the Swiss+Tech light on, and slide the switch forward (toward the LED) until it clicks to turn the flashlight off.

To change the batteries in the Swiss+Tech, turn the light upside down, and use a small (#0) phillips screwdriver to unscrew and remove the four screws. Set the screws aside, where you won't lose them. Swing the bottom half of the case away, using the split ring on the tail as a hinge. Remove the two used CR2016 cells from the flashlight, and dispose of or recycle them as you see fit.

Insert two new CR2016 cells in the flashlight body, orienting them so the button-end (-) negative faces up. Be sure both cells go under the LED lead. Swing the bottom half of the flashlight back over, and press it in place. Screw in the four screws you removed at the beginning, and that's pretty much it.

Battery life is not stated on the packaging. One user of this product recommends changing the batteries after 3-4 hours of use.

I did not see anything wrong with the switch. So I spread the LED leads apart very slightly before reassembling the flashlight, and the switch did lock on if I really tried (for three activations), then resumed its former momentary mode. So I still have a unit with no continuous-on switch, but it's relatively minor in the grand scheme of things and I'll live with it.

The Swiss+Tech appears at least reasonably durable, and I don't believe ordinary flashlight accidents will cause it to become broken. Since I'm currently running a longevity test on another table that hosts a steel rod (the one I beat flashlights against), I can't try to punish this flashlight in that manner until the test is complete - probably within a week.

I did step on it a few times and did not break or damage it, so it's at least durable to that extent.

The Swiss+Tech is not water-resistant or submersible. There are no O-rings between the case halves, around the switch, or around the LED, so it'll probably get flooded if it falls into water. If it falls into water, take it apart (as you might for a battery change), and put the parts in a warm, dry place for a day or so before reassembling it. If it falls into seawater or if something pisses on it, douche the parts off with fresh water before setting them out to dry.

The Swiss+Tech has an icy cool slightly bluish-white light, which is pleasant to use; some people might prefer a warmer colored light though, and might not like this flashlight very much because of that. Color is not something I can quantify with a meter, so my opinions of it are going to be rather subjective. Your results may vary.

This isn't that bright, but it's not so dim as to piss me off.
Light has an icy cool white color to it.
