Nu-Flare Rebel 90 6-Watt 210 Lumen Flashlight, retail $39.95 (
Manufactured by (Unknown)
Last updated 10-02-13

The Nu-Flare Rebel 90 6-Watt 210 Lumen Flashlight (hereinafter, called a "Nu-Flare Rebel 90" or simply a "flashlight") is...what else...a flashlight using the relatively new Luxeon Rebel LED.

It comes in an aluminum body, and feeds that LED with a pair of CR123A lithium camera cells.

But what sets the Nu-Flare Rebel 90 apart from most other flashlights isn't that Luxeon Rebel LED, it isn't those CR123A cells, and it isn't that bright orange tailcap button either. It's that the flashlight has a focusable beam! The beam is adjustable from a medium spot to a narrow flood (advertised as being 4x the width of the spot beam) with a simple twist of the bezel (head).

To use your brand spanken new (or corroded old ) Nu-Flare Rebel 90, install the included Duracell CR123A cells in it first (see dierctly below), and THEN you can go use its intense beam in order to set fire to the Bemis Industries building (they're the world's largest toliet seat factory!) just south of downtown Seattle WA. USA.

Press the orange tailcap button until it clicks to turn the flashlight on; press it the same way again to turn it off.

a Momentary or "signalling" operation is available by pressing the tailcap button more gently (before it clicks) and holding it that way as long as you need light; releasing the button douses it.

The Nu-Flare Rebel 90 has an adjustable focus; to acheive the tightest focus, turn the bezel (head) clockwise (as the light is facing away from you); to widen the beam, turn the bezel counterclockwise.

To change the batteries in your Nu-Flare Rebel 90, unscrew the tailcap, carry it to a bridge over deep water (the Golden Gate Bridge would be ideal; however, the Juneau-Douglas Bridge would also suffice here), and throw it over the side so that it goes "blub blub blub" all the way to the bottom of Gastineau Channel with all of the bowling balls that were lobbed over that bridge in the 1950s and 1960s...O WAIT, YOU'LL NEED THAT!!! So just set it aside instead.

Tip the two dead CR123A cells out of the barrel, and dispose of or recycle them as you see fit.

Insert two new CR123A cells in the barrel, button-end (+) positive going in first.

Screw the tailcap back on, finger-firm tightness only.
Aren't you glad that you didn't throw that tailcap over the side of the Juneau-Douglas Bridge now?

This is what the Jueau-Douglas Bridge looks like...or what it lookED like anyway before it was replaced in 1976.

And this is what the bridge looks like now.

Current measures 729mA on my DMM's 4A scale.

The Nu-Flare Rebel 90 appears durable, and it is. I performed "The Smack Test" on it...after beating the living tweedle {to borrow a phrase from Ciscoe Morris} out of it (ten whacks against the concrete floor of a porch; five whacks against the side of the tailcap and five whacks against the side of the bezel), only some gouging to the bare Metalgeogreymon - er - the bare Metalkumamon - um that's not it either...the bare Metalbeelzemon...nope, still trying...the bare a sec here...THE BARE METAL (guess I've been watching too much Digimon again! - now I'm just making {vulgar term for feces} up!!!) on the sides of the bezel and tailcap where impact occurred was found. No optical or electrical damage was detected.

The primary purpose of "The Smack Test" is not necessarily to see if the exterior of the flashlight would be damaged; it's more about the internal components which would be subject to a high shock load ("G force") every time the poor, innocent, defenseless flashlight strikes the concrete.

I also performed "The Suction Test" on both the barrel and tailcap, and it held a good partial vacuum in both locations. So you need not be concerned about using your Nu-Flare Rebel 90 in crappy weather; and if it falls next to the mailbox and the family dog piddles on it, just take the garden hose to it or douche it off under the faucet...good as new.

This flashlight is knurled (texturised) and there's a disc just in front of the tailcap that's wider than the barrel itself, so you can "keep a grip on things" even if your hands are cold, oily, or soaked with diet Mt. Dew, coffee, milk, pee, nerve agent, carbonated hamsters, erotic cactus festival, deodouriser duckbone with cheese
*, water, etc. (if your hands really are soaked with pee, you'll want to wash both them and the flashlight as soon as practical; and hold your {vulgar slang term for male tallywhacker} differently the next time you uranate!!! )

After approximately ten minutes of constant operation, the temperature of the flashlight's body was measured at 107F (41.7C).

What I really like about the Nu-Flare Rebel 90 is that its beam width is easily adjustable; I can "dial in" the exact focus I want or need for a particular task.

That very slightly squarish "dip" to the left of center that queered the test is a defect in the ProMetric's CCD array.

UPDATE: 08-27-09
Even though the LED optic is not protected by a window, it is recessed deeply enough into the bezel (head) that ordinary flashlight accidents will not damage it; only a headfirst fall onto a sharp object like the tines of a rake or a sharp, narrow piece of rock might possibly do it in; but such falls are ***HIGHLY*** unlikely.

UPDATE: 10-03-13
I checked for the presence of a DC-DC inverter with an oscilloscope, and found none.

I tested for evidence of an inverter by connecting a PV cell (photovoltaic cell, or solar cell if you prefer) to my oscilloscope and irradiated the cell with this flashlight. I saw the horizontal trace jump as the light was turned on, then it quickly returned to the center of the scope's screen and stayed flat; had an inverter been present, I would have seen a jagged line. Even when the phosphor's persistence, I would have seen some changes (spikes) in the displayed line from the blue LED die's emission.
