Streamlight Jr. Luxeon Flashlight, retail $30 (
Manufactured by Streamlight (
Last updated 10-17-04

The Streamlight Jr. Luxeon is a small LED flashlight that has a 1.2 watt Luxeon LED and what I believe is a NX05 acrylic optic in the head, powered by two ordinary AA cells.

The flashlight comes in an aluminum body, finished in a Type II black anodized finish. It also comes with a bezel-up belt holster if you wish to use it.

I took mine apart, and there's a LD (Low Dome, or batwing) Luxeon LED in there.


Remove the Streamlight Jr. from the plastic hell it comes in by slitting one of the sides and the bottom of the package with a knife or razor blade.

Once the flashlight, the included pair of Duracells, and the belt holster are out, install the batteries (see below) and then you'll be ready to rock.

Press the rubberised tailcap button until it clicks and then release it to turn the Streamlight Jr. on. Press and release it the same way again to turn it off. This is continuous mode.

Press the rubberized button less firmly (before it clicks) and hold it that way to get momentary or signalling mode. Release the button to turn the Streamlight Jr. back off.

Things just don't get much easier than this...well, not flashlights, anyway.

The Streamlight Jr. comes with a nylon belt holster. The flashlight fits in it bezel (head) up.
Since I do not own or use pants that require a belt, I cannot test this accessory in the manner in which it was intended.

To change the batteries in the Streamlight Jr., unscrew and remove the tailcap, throw it in the toilet, and flush it away...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead. ;-)

If necessary, tip the two dead batteries out of the barrel and into your hand, and dispose of or recycle them as you see fit.

Insert two new AA cells in the barrel, button-end (+) positive first. Screw the tailcap on, and be done with it.
Aren't you glad you didn't flush away that tailcap now? ;-)

Current consumption is 623mA on the Duracell alkalines that were included with it.
Because there is a step-up converter circuit in there, the LED really isn't seeing 623mA.

The Streamlight Jr. flashlight appears to be quite durable. I beat it against a steel rod ten times (five on the bezel, five on the tailcap) and did not damage the flashlight in any way I can detect, and it still functions properly.

(Update 10-15-04): I repeated the smack test against a concrete sidewalk, and found no damage whatsoever on the tailcap, and only very minor damage on the bezel. No electrical or optical malfunctions were detected.

It is at very minimum weather-resistant; I removed the tailcap, relieved the flashlight of its batteries, performed that dreadful suction test on it, and it held a vaccume (vacum, vaccuume, vaccumn, vaccuummnne, vacuum, etc.), so I believe it will easily withstand being rained or snowed on, and falls into shallow water should not do it in either. I can't test the switch/tailcap assembly the same way, but the bezel passed the suction test, and the threaded portion is protected by an O-ring, so I don't think it will leak during foul weather use or shallow water landings.

The Streamlight Jr. is covered in what I believe is a Type II anodized finish. I was fairly easily able to scratch through the finish with the blade of a Swiss army knife.
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 bezel (head) can be removed if desired, but it's really not recommended because you don't need to change bulbs or anything else in there. There is a LD (Low Dome, or batwing) Luxeon LED, connected to a boost/regulator circuit, to which a plastic polarity protection disc is loosely affixed - if the aluminum "reflector" is unscrewed and removed, these can come out of the flashlight and maybe fall on the floor and get stepped on if you aren't paying attention.

There is knurling (diamond-shaped texturising) on the bezel and barrel; this helps aid in retention (the ability to hold the flashlight when your hands are cold, oily, or wet) so I don't think retention will be a very significant issue at all.
This knurling isn't aggressive (sharp), so it should not cut holes in your pocket if you decide to carry the Streamlight Jr. that way.

Some battery rattle is noticeable when the flashlight is shaken. In my opinion, this is not a significant fault, but it exists nonetheless, so on this web page it goes.

The beam's central hotspot has a slight square or diamond appearance to it, but the penumbra surrounding the hotspot is circular. The squarish hotspot does not in any way affect the use of the flashlight, and in my opinion, you do not need to get used to it beforehand like you might with rear-firing flashlights like the Pelican Sabrelite LED or the Lightwave Infiniton C1 flashlights.

Beam photo at ~12".
Measures 430,000mcd on a Meterman LM631 light meter.

Beam photo at ~6'.

The beam is a pure white color, with no yellow, blue, purple, or "rotten dog
urine green" anywhere in it. Not in the hotspot, not in the corona either.

Test unit was purchased in a Candlepower Forums group buy on 07-02-04, and was received on the afternoon of 07-17-04.

UPDATE: 00-00-00

Feels reasonably good in the hand
Water-resistant (when bezel is screwed on anyway)
Bezel can be removed for candle use - water resistance will be lost if you do this though
Decent brightness for a one LED flashlight
Has a step-up circuit to reduce the number of batteries needed and keep size & weight down

Has a Type II anodizing, which can become scratched up
Higher than expected current draw (623mA)
