This is the Costco 1W Luxeon flashlight. It comes in a handsome aluminum body, has a Luxeon I LED behind an acrylic optic, and feeds from two AA cells.


SIZE



Press the black rubberised button on the tailcap very firmly until it clicks and then release it to turn it on.

Press and release the button the same way again to turn the flashlight on back off.

There is no momentary or signalling mode available in this flashlight when it's off, however you can blink the flashlight while it is on by partially depressing the button. If you don't mind the backward or reverse feeling of this, you can blink the flashlight this way if necessary.

The flashlight comes with a fairly generous wrist strap. This strap is large enough to go around the flashlight, so you can use this strap to hang the flashlight from thin tree branches, thin water pipes, or other long thin objects with no readily accessible "end".



To change the batteries, unscrew and remove the tailcap, gently place it on the ground, and kick it in the garden so the praying mantids will think it's something yummy to eat and subsequently strike at it...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

Tip the old used-up AA cells out of the barrel and into your hand, and dispose of or recycle them as you see fit.

Slide two new AA cells in the flashlight barrel, orienting them so their button-ends (+) positives go in first. Finally, screw the tailcap firmly back on.
Aren't you glad you didn't kick that tailcap into the garden with all those hungry, hungry praying mantids now?

Current usage measures 587mA on my DMM's 4A scale.



This is a loaner. So I won't throw it against the wall, stomp on it, try to drown it in the toilet bowl or the cistern, run over it, swing it against the concrete floor of a patio, bash it open to check it for candiosity, fire it from the cannonada (I guess I've been watching the TV program "Viva Piņata" too much again - candiosity is usually checked with a laser-type device or a handheld wand), send it to the Daystrom Institute for additional analysis, or inflict upon it punishments that flashlights may have inflicted upon them.
So this section of the flashlight's web page will seem a bit more bare than this section of the web page on a page about a flashlight that is not a loaner sample.

I performed that dreadful suction test on it, and it held a good partial vacuum - including the tailcap. So I would call it waterproof and even submersible to shallow depths too.

The light produced by this flashlight is a cool, pure white, with no red, pink, yellow, blue, purple, or "rotten polar bear urine green" tint to it at all. Not in the hotspot, not in the corona either.
