This is an LED "penlight" that, while initally brighter than many, does come with some unwanted baggage.
This penlight uses five 5mm phosphor white LEDs to produce a remarkably potent medium spot with soft corona.
It gets its power from three LR44 button cells, which are included (and already installed) in the penlight.
And that's the "baggage" that I just eluded to: while it will start off bright, with a current consumption of 102.2mA, won't stay bright for very long on those itty bitty button cells.
SIZE
To turn the penlight on, press & release the tailcap.
To turn the penlight off, just do the same thing.
Things just don't get much easier than this -- well, not flashlights anyway.
To change the LR44 button cells in this penlight, unscrew and remove the tailcap, huck it out your kitchen window so that a dustcart (garbage truck) comes along, runs over it, and flattens it...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.
Tip the "dead-as-a-doorknob" LR44 cells from the barrel and dispose of them into the dustbin (garbage can) or drop them into the battery recycling box if your community has a battery reclamation program in place.
Stack three new LR44 button cells near the edge of a table or desk, orienting them so that their button-ends (-) negatives face up. Lower the barrel of the light over them, and slide the whole mess toward the edge of the table, using your thumb to prevent those button cells from simply clattering to the floor.
Invert (tip over) the light so that the open end now faces up, and remove your thumb.
Finally, carefully screw that tailcap back on.
Aren't you glad that you didn't chuck it out the window now?
Current usage measures 102.2mA on my DMM's 200mA scale.
That's a lot of current to ask out of those tiny button cells; battery life is going to be a significant issue here.
The tailcap is INCREDIBLY EASY to crossthread when reassembling the flashlight following a battery change.
The penlight appears to be at least reasonably durable -- to the point that it should not just fall apart through casual handling or use. Since smaller lights tend to fare quite well on The Smack Test, I decided to administer that test to this product.
I bashed it against a brick wall ten times (five against the side of the bezel, and five against the side of the tailcap) and was able to expose the bare Metalmarineangemon - er - the bare Metaltrailmon - um that's not it either...the bare Metalmegidramon...er...uh...wait 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 side of the bezel and tailcap where it was struck.
The split ring fell off during the latter part of the test, but the product itself still functions as intended.
Here is a video on YourTube showing this test:
The 5x LED Penlight (mainly) passing The Smack Test.
No electrical or optical malfunctions were detected.
Here is a pic of the flashlight and split ring after The Smack Test.
The purpose of The Smack Test isn't to see how badly damaged the external parts of the penlight would become; it gauges how well (or how poorly) the LED and driver circuit (if present) handles the instantaneous G-forces encountered during this test. The 5x LED Penlight passed the test quite readily.
I did suction the barrel and detected a leak -- it was a HUGE leak like I've found in other lights (large enough that I was actually sucking the batteries right out of the flashlight!), so water-resistance is minimal at best.

Honestly, I just can't envision myself rating this cute little light very highly at all.
It's got decent looks, but a turd floating in a punchbowl is still a turd.

Spectrographic analysis of the white LEDs in this flashlight.
Spectrographic analysis of the white LEDs in this flashlight; spectrometer's response narrowed to a band between 440nm and 460nm to pinpoint native emission peak wavelength, which is 448.350nm.
The raw spectrometer data (tab-delimited that can be loaded into Excel) is at 5pen.txt
A beam cross-sectional analysis would normally appear here, but the ProMetric System
that I use for that test was destroyed by lightning in mid-July 2013.
TEST NOTES:
Test unit was purchased from the Happy Market located at the intersection of N. Maple Ave. and W. Shields Ave. in Fresno CA. USA on 06-04-20.
UPDATE: 06-09-20
The product has failed. I suspect that the pushbutton switch went to pot following being thoroughly douched in toliet water from The Toliet Test; using a piece of metal to connect the flashlight barrel to the battery (+) positive resulted in light 100% of the time; using the pushbutton switch as intended resulted in light less than 1% of the time.
Therefore, the always dreadful, "" will be appended to its listings on this website at once.
UPDATE: 10-06-20
Light has inexplicably begun to function again.
UPDATE: 11-08-20
Those tiny button cells are still going.
I'm actually pleasantly surprised at how well they're holding up!
