The Flash Fire is another entry in the blue LED flashlight racket by LED LENSER, a German company that produces very futuristic (and artistic) looking flashlight products. This light features a blue LED, and comes with a wand that screws onto the end to make the light visible from the sides -- it's quite the attention-getter actually.

It also features two blink speeds plus steady-on modes; all accessible with a single pushbutton on the product's barrel.


Like all LED LENSER products, the Flash Fire comes ready to use straight from the box. Pressing the barrel-mounted pushbutton once causes the unit to blink slowly.

Pressing again causes the unit to blink rapidly.

Pressing again turns the unit on in steady-on mode.

Pressing again turns the Flash Fire all of the way off.

The included wand can be affixed to the product by simply screwing it onto the "business-end" of the Flash Fire.
Doing so means that the light will be visible from the sides as well as head-on.

To change the batteries, unscrew & remove the tailcap, and discard the deadwood. The light takes 4 not-so-common AG5 button cells. The easiest way to get them in is to stack them on a table with the button end facing up; and lower the barrel of the Flash Fire directly over them. Then you can either pinch your thumb & forefinger around the bottom as you lift and flip it over (so the batteries don't fall right out), or slide a business card underneath, and then lift the barrel & card at the same time and flip it over. Then just screw the end cap back on firmly.

The batteries were deader than doorknobs in the test unit, and I had no AG5 button cells handy (actually, I was unaware that AG5 cells even existed until I noted that this product uses them!!!), so I used four LR41 button cells and stretched the tailcap spring so that continuity could be established with the smaller cells (primarily resulting in a shorter battery stack).

The Flash Fire is reasonably well-built for a keychain light. The housing is all aluminum. However, due to its small size, "The Smack Test" would simply be inappropriate here.

Although there is an O ring on the tailcap, the Flash Fire is *not* water resistant at all, and will fill up fairly quickly (through the bezel area and possibly around the switch button as well) if it falls in the toliet or goes down the storm drain.

Test unit was furnished by an unknown company, retailer, or individual sometime in 2003 or 2004; it was found while reorganising my flashlight shelves on the afternoon of 12-06-09.

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.
