Review of Streamlight Jr. LED C4 - update
The flashlight seems to be working great so far. About the only comment I have at this point is that the clip could use some re-designing – maybe along the lines of a slightly larger Microstream® clip. The present Jr. clip looks like it was borrowed right off one of those ubiquitous industrial ballpoint stick pens. It’s a bit too narrow, pointed, and weak for use on this flashlight. This is a minor complaint and overall I love the flashlight. I wouldn’t mind seeing it in a ProPolymer version with various safety ratings. Although there is the new ProPolymer 2AA LED flashlight, it appears to be a lower-output, long run-time design.
I give the Streamlight Jr. LED C4 four and a half stars. I.

Before I headed back to Kuwait I ordered a couple of brand-new flashlights from Brightguy to take with me (good flashlights are hard to find over there). Of course I have my Pelican M6 xenon for “serious situations”, but for everyday use I really wanted something that runs on more commonly available batteries. So I decided on the Streamlight Jr. LED C4 as a general all-around flashlight and the Streamlight Microstream as a key chain light.
My first impressions of the Jr. LED C4 were extremely positive (as with all Streamlight products), but unfortunately after getting to Kuwait it seems to have suffered from what is known in the electronics business as “infant mortality” after only a few days out of the package and a few minutes of use.
I have owned the previous two versions of the Jr. LED. This one, the “C4” version, is definitely much brighter than its predecessors and drew 550 mA on a new set of alkalines, lending credibility to the claim of up to four hours’ run time. The specified 55 lumens output seems about right as well. As far as “throw”, I would estimate that it has almost 3/4 of the beam candlepower of the excellent (and larger) Streamlight ProPolymer 4AA Luxeon, based on a side-by-side test into some distant trees (both with new sets of alkalines). The ProPolymer, which I left with my family stateside, is rated at 3,500 candlepower.
This flashlight is equipped with a “Cree 012” LED board in the flashlight head in conjunction with a half textured/half smooth deep reflector (in contrast to the plastic collimator lens used on the previous versions of the Jr.). The flashlight has an excellent beam with a tight round spot in the center and copious amounts of side-spill. I found that unscrewing the head a bit led to a slightly tighter focus, but the head might eventually come loose and fall off in this arrangement unless a thicker O-ring is used. The LED provides very smooth white light with only one small outer ring of yellow in the side-spill, which is barely noticeable.
The clickie on-off switch allows for momentary press-on, which is nice for signaling, etc. However, the flashlight cannot stand on end due to the pointed switch.
I tested the flashlight with some almost-dead alkalines, and it still turned on properly and provided reasonable (though lower) light output. In one of my previous Jr.’s, the light would not reliably turn on when the alkaline batteries started to get to about the half-depleted level.
This flashlight was really impressively bright (to the point that one might consider employing it for “interpersonal” applications), but a few days after I started using it (with only a few minutes of total “on” time), I noticed that the LED began flickering slightly. I want to emphasize that, up to this point, I never used lithium batteries in the unit (which would probably not be a good idea because the flashlight is running full bore as it is) and I didn’t drop it or otherwise damage it. I used some NiMH batteries one time for about five seconds when I first received the flashlight to test the output with rechargeables (which wasn’t noticeably different than with alkalines), but otherwise only used alkaline batteries. However, after the flashlight started flickering, I put in some NiMH’s because I wanted to do a long burn-in to see if this would stabilize the electronics and I didn’t want to waste my alkalines. I bypassed the clickie switch to rule that out as the source of the problem. I looked at the LED board, thinking maybe it had a bad solder joint. I wasn’t able to see a problem there. I tapped the flashlight while it was turned on, which made no difference, so I ruled out a bad solder joint or broken board trace and instead suspected a problem with the voltage step-up electronics (in retrospect, the flickering may be indicative of an internal LED failure). During testing, the flashlight head became quite warm, so I put it in the freezer (still turned on), thinking that the electronics would behave differently in the cold. They sure did. In fact, the flashlight stopped working completely after several minutes.
I took the flashlight out and warmed it up. Eventually it came back to life, albeit very dimly. To rule out a problem with the NiMH’s getting cold, I popped in the alkalines. No major difference. After getting back to room temperature, the flashlight became a little brighter, but no where near where it was before I chilled it – maybe about 1/2 the output. And it’s still flickering. Hopefully I merely received a defective unit and this is not indicative of a design problem with the flashlight as a whole. See All Reviews
