The Trilogy is a small incandescent flashlight sold by Ray-O-Vac.

It comes in a plastic body, and feeds its small incandescent light bulb with a single AAA cell.

It is good looking, but it does not appear exceptionally durable and it is definitely not waterproof or submersible. But it *WILL* produce light of sufficient intensity to locate a keyhole, find that dropped armpit deodouriser cap that rolled behind the toilet, get the cat food from the little cabinet under the kitchen sink, etc.


To use the Trilogy, feed it the included AAA cell first (see directly below), and then you can go to town.

Slide the switch on its barrel forward to turn the flashlight on; slide it backward to turn the flashlight off.

To change the battery, unscrew and remove the bezel, gently place it on the ground, and kick it into the garden so the hungry, hungry praying mantids will think it's something yummy to eat and subsequently strike at it...O WAIT!!! THAT'S THE GOOD PART!!! So just set it aside instead.

Tip the used AAA cell out of the barrel, and dispose of or recycle it as you see fit.

Slide a new AAA cell in the flashlight barrel, orienting it so the flat-end (-) negative goes in first. Finally, screw the bezel back on.
Aren't you glad you didn't kick that bezel into the garden with all those hungry praying mantids now?

Here is what a praying mantis looks like.

Unable to measure current consumption due to how the Trilogy was constructed.

Since this is an incandescent flashight, sooner or later you're going to have to change the bub.

To do that, unscrew and remove the bezel, and place the barrel someplace where it won't roll away & disappear or get stepped on.
With the bezel face-down, turn the black piece with the gold-colored metal band on it counterclockwise (as though loosening it) approximately 1/4 of a turn, and lift it off.

Using your fingers, pull the blown bulb straight out, and dispose of it.

Insert a new bipin bulb into this piece, so the pins on the new bulb fit into the openings for them - use another flashlight to look for these openings if necessary.

Place this piece back on the back of the bezel, and turn it clockwise (as though tightening it) approximately 1/4 of a turn.

Screw the bezel back onto the barrel, and be done with it.

This unit is of all-plastic construction, so "The Smack Test" really wouldn't be appropriate here.

Same with "The Toilet Test"...not because somebody else lives here, but because the product is not waterproof or submersible. When I removed the bezel & suctioned the barrel, substantial air leakage was detected. I think it is very lightly splash-resistant at best, but it is not waterproof or submersible. So please try not to drop it in creeks, rivers, ponds, lakes, oceansides, docksides, puddles of Kodiak bear pee, slush piles, mud puddles, tubs, toilet bowls, cisterns, sinks, fishtanks, dog water dishes, or other places where water or water-like liquids might be found.

If it fell in water and you suspect it got flooded, remove the bezel and batteries, empty the water out of the body if necessary, and set all the parts in a warm dry place for a day or so just to be sure it's completely dry inside before you reassemble and use it again.

If it fell into seawater or if somebody or something peed on it, douche it out with fresh water before setting it out to dry. You don't want your Trilogy to smell like seashells or wee-wee when you go to use it next. Besides, salt (from seawater or piss) can't be very good for the insides.

The light produced by the Trilogy is a distinctly yellow-white, but not nearly as dim as many other one AAA cell flashlights. So yes, it would indeed be more useful in dark situations than many other one-cell incandescents of similar size.

Measures 47.7cd on a Meterman LM631 light meter.
The beam is quite narrow; this accounts in large part for the high reading.

Test unit was purchased at Wallgreens in Seattle WA. USA on 03-22-05.

Product was made in China. A product's country of origin really does matter to some people, which is why I published it on this web page.
