The Sapphire (part number GNF-008) flashlight is a high-output LED flashlight that comes in an almost all-aluminum body, and uses three AAA cells to power the non-Luxeon high-powered LED that produces its light.

The high-powered LED inside is made by Hewlett-Packard; and it was originally designed to be used in street signs. The flashlight uses a smooth reflector to produce its beam.


SIZE



Feed the flashlight its included batteries first (see directly below), and then you'll be ready to roll.

Press the rubberised button on the barrel firmly until it clicks and then release it to get light. Press and release the button the same way again to not get light. This is continuous mode.

There is no momentary or signalling mode available when the Sapphire is off, but you can blink the flashlight when it's on by pressing and holding the button in for as long as you want the flashlight off.



To change the batteries in the Sapphire, unscrew and remove the tailcap, dash it to the ground, and stomp on it with old or used bowling shoes...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

Tip the open end of the barrel into your hand, and remove the black battery carriage. If necessary, remove and dispose of or recycle the used AAA cells from this carriage.

Insert three new AAA cells in the carriage, orienting the flat-end (-) negative of each cell with the spring for it in each chamber.

When the carriage is full, insert it into the flashlight barrel, orienting it so the metal pin on one end of the carriage goes in first. Screw the tailcap back on, and be done with it.
Aren't you glad you didn't stomp on that tailcap now?

Due to the way the Sapphire is constructed, I am not able to measure current.



The Sapphire is reasonably durable. It survived my smack test (ten whacks against the corner of a concrete stair; five against the side of the bezel and five against the side of the tailcap), and I found the expected minor gouging on the side of the bezel and tailcap where it was struck - no surprises there. No optical or electrical malfunctions were detected.

The flashlight has a clear Type II anodizing on it. I was able to scratch through the finish with the blade of a Swiss army knife. It is more than reasonably durable though. So it should stay looking new for a long time, even if it goes up against keys or flashlights during storage or transportation.
Would I really try to cut up a brand spanken new flashlight?
You bet your sweet patootie I would, if it's in the name of science.

The Sapphire is weather-resistant and even submersible to shallow depths at minimum; as I removed the tailcap and performed that dreadful suction test. It held a vaccume (vacum, vaccuummnne, vaccum, vacuume, vacumn, vacuum, etc), so it should not flood when used in foul weather, and shallow water landings should not kill it either.

The Sapphire has knurling (crosshatch-shaped texturising) on the barrel, and longitudinal ribs machined into the bezel and tailcap, so retention (the ability to hold onto the flashlight when your hands are cold, wet, or oily) should not be much of an issue.

A wrist lanyard is affixed to the Sapphire via a center post on the tailcap. This lanyard is long enough to go all the way around the flashlight, so it may be hung from a horizontal pole, small diameter pipe, small diameter tree branch with no readily accessible "end", etc.

Beam color is overall a very slightly bluish white, with a more pure white corona. It is not objectionable in any way, shape, or form.
If you entered a large room full of people, turned this flashlight on, and then asked them to tell you what color it was, 100% of them would shout out "WHITE!!!" for sure.

The high-powered LED inside is made by Hewlett-Packard; and it was originally designed to be used in street signs.


Here is a closeup of the LED itself. The light-emitting region is that yellow circle near the center with those twelve whisker-thin gold colored wires going into it.

According to the person who provided the flashlight, HP designed the chip; they sold the license and/or patent to a company in China to manufacture and sell it.

You can remove the bezel (head) to use the flashlight in candle mode. It will stand on its tailcap even with the lanyard attached. You will lose water-resistance in this mode, so please do not remove the bezel outdoors in the rain or snow.
