The Sneaklight might look a bit like a Photon II, but it has one very important difference: a built-in clip that allows you to affix it to the bill of a baseball hat. Whether that is enough of a difference that LRI won't ask me to take down this page remains to be seen.

The Sneaklight has a brilliant white LED in the end, and that LED is powered by two CR2016 lithium coin cells. The Sneaklight can be used in momentary mode by squeezing it, or in continuous mode via an on/off slide switch on the upper surface of the flashlight not too far from the LED.

It comes in a translucent, slightly milky white plastic case, to which a spring-loaded metal clip is affixed. It also comes with a ball-type loop chain, so it can be hung from just about anything - within reason, of course. Both of these attachments can be seen in the above photograph.


SIZE



The Sneaklight is ready to use as soon as you remove it from the package.

To activate it in momentary (signalling) mode, just squeeze the two case halves together, and hold it that way for as long as you need light. Quit squeezing to turn the Sneaklight off.

For continuous (hands-free) mode, use your thumbnail to slide the slide switch on the top of the flashlight back (towards the tail) until it clicks. Slide the switch forward (toward the LED) until it clicks to turn the Sneaklight back off.

To use the clip, squeeze the handles of the clip until the jaws open wide enough to clip to a hat or other article, then release the handles to lock it in place. The Sneaklight swivels a full 360° on its nylon tail post, so it can be aimed wherever you need the light.


Here it is clipped to the bill of a baseball hat.
In this photograph, the Sneaklight was clipped upside-down to the bill of the hat so it would aim somewhat downward, instead of upward. It can be swivelled left or right to suit your needs.



To change the batteries in your Sneaklight, first, go get a small dish to hold all the loose parts.

DISASSEMBLY: Remove the nylon screw and nut assembly by using a standard screwdriver to insert into the screw head and unscrew it. When you have unscrewed the parts, place the screw, nut, and clip in the dish.

Remove the four phillips screws from the bottom of the flashlight case with a #0 phillips screwdriver, and place these in the dish too.

Open the two housing halves, remove the used batteries, and dispose of or recycle them as you see fit. The LED will probably come out, so put it in the dish too.

REASSEMBLY: Set the two housing halves on a paper napkin.

Install the LED in the bottom half of the housing, with the long lead resting on the small post, epoxy LED-end as top - the shorter LED lead should go down right side of post. Be sure it's fully seated.

Press one of the new CR2016 cells into the lower half of the housing, flat-side (+) positive down. Then install the other new CR2016 cell, flat-side (+) positive down, and be sure the LED lead that's showing isn't squished down by the battery, but is instead positioned on top of it.

Assemble the switch, in the "off" position (toward LED).

Flip over assembled bottom half of the housing and install over the top half of the housing, ensuring the long lead of the LED fits into the groove of the switch for it. Light should be off when the halves are together.

While holding the Sneaklight together, test it to be sure it works.

Screw in the four phillips screws.

Replace nylon screw through the flashlight housing (switch-end up), pass it through the opening in the clip, and put the nylon nut on. Tighten the screw with a standard screwdriver, and there, you're done.

This is the procedure given on the instruction card.



The Sneaklight is reasonably durable. I whacked it against a steel rod ten times (five on the top, and five on the bottom), and no damage was detected, and the light still functions properly.

I believe it is weather-resistant, but I don't think it's totally waterproof or submersible. There are no O-rings or other forms of environmental protection on this flashlight. A suction test showed there is significant leakage, so weather-resistant, probably. Submersible, no.

The Sneaklight has been changed since I purchased these samples. Has to do only with the nylon nut on the underside of the clip. My contact at Playwrites started cutting down the points of the nut between the flats to allow the nylon nut to recess more allowing a straighter shot for the nylon screw to access the nut. To this screw he adds a touch of removable Locktight and sets the tightness for some tension. He also adds some dry teflon lube to the works to ensure a nice glide.

More later...let me just FTP this page up now and call it a night.
