LED Light

The Tektite Expedition 1900 is the big brother to C.Crane's Expedition.
Boasting an impressive array of 19 super bright white Nichia LEDs, this flashlight is the new reigning king when it comes to bright white LED flashlights. The sturdy ABS plastic & Lexan flashlight is powered by three "C" cells, and it comes with a comfortable, adjustable wrist strap and lanyard.


The Expedition 1900 comes packaged with three Energizer alkaline "C" cells. Install them (see below) and you're good to go with no additional assembly.
To turn the light on, twist the Lexan lens bezel clockwise; to switch the flashlight off, unscrew the bezel 1/4 turn or so until it shuts off. This is one flashlight you probably will not want to stare directly into while it's on, as it produces a very intense white light.

When you receive your Expedition 1900, it will need to be fed. To do this, unscrew the lens bezel completely until it comes off. Then remove the silver reflector & LED board. Holding the light at an angle with the open end facing upwards, slide in the three "C" cells with the button-end facing up. Lay the LED board on top of the uppermost battery, fit the silver reflector on (being sure the notch on the inner face fits into the empty space on the edge of the LED board) and screw the bezel back on.

Because of the loose parts, you do not want to empty this flashlight directly over the toilet bowl or garbage when changing batteries, or else you will end up dumpster diving for them.

Battery life is stated at 15 to 20 hours, which although not as long as some LED flashlights, is still much longer than any incandescent. Remember, this flashlight was designed for extremely high brightness rather than extreme battery life, and 19 LEDs do require significantly more power than three or four.

The Expedition 1900 is a tough, though slightly brittle feeling flashlight. However, the body is composed of ABS plastic, and the lens is made of G.E. Lexan, the strongest transparent plastic made by Man. So it should never break as a result of common flashlight accidents like falling off a table, car hood, or out of a backpack.

It is also visibly sealed with "O" rings and is guaranteed waterproof to 1,000 feet.
These "O" rings also help seal out dust & dirt, making cleanup of a dirty flashlight a simple "hose down" operation.
The ABS case is resistant to oils and various other materials (presumably also including gasoline) so this light should fare well in a garage as well as it does on the campground.

When dropped or tossed to a missed target, the Expedition 1900 hits the floor with a loud smack, but always comes back ready for more. Drop tests have been limited (the neighbors are bitching) so later on I'll take a bunch of these things for a little road trip and see what they can take.

The Expedition 1900 comes with an adjustable wrist lanyard with a length of rubber tubing covering part of it for a comfortable, secure, non-slip fit around the arm or wrist in any weather. An optional hands-free strap can be fitted into the two wide loops located just behind the flashlight head.

Try this with any other LED flashlight. It doesn't work with any other.

Any updates related to this review will be posted as they happen.

UPDATE 04-11-01:
I've observed that after a short period of usage, all of the LEDs adjacent to the catalyst carrier become deflected to the left or right. This is because the reflector and the LED board are seperate, and the protruding tab in the reflector pushes the LEDs over.

I'm experimenting with a fix involving cementing the LED board to the reflector assembly with G.E. silicone RTV. If this works, it will be suggested as a standard fix for all flashlights of this type with any LEDs on the outer edge of the board.

UPDATE 04-12-01:
The "fix" seems to be holding up fine. Would I really beat the piss out of a $135 flashlight just to test the board modification? You bet your sweet patootie I will! The light has been tossed to the floor several times, and beaten against a steel rod half a dozen times. So far, the only "damage" is some slight dents in the outer casing. The LEDs haven't shifted and the board hasn't broken free of the reflector base. It still works as good as new - perhaps even a bit better than new since the LEDs no longer get whacked out of alignment by the catalyst holder.

Durable construction, waterproof, uses cheap & common batteries, excellent battery life, brightest $&!*#% LED flashlight money can buy.

One-handed operation is not possible. Won't stand up on-end by itself.
