LED FLASHLIGHT/WORK LIGHT (1)

LED Flashlight/Work Light (1), retail $3.99 (http://groceryoutlet.com*)
Manufactured by (Unknown)
Last updated 07-03-13

The LED Flashlight/Work Light (1) is a somewhat unusual looking but ultimately useful little light that has 36 wide-angle white LEDs in the handle, four garden variety white LEDs in the head, and uses four AAA cells (included) to power those LEDs with.

It comes in a black & green plastic body, and it has a magnet on the back to allow you to affix it to just about any flat, ferrous (iron-containing; such as automobile hoods) magnetic (such as iron, mild steel, cobalt, or nickel) surface.

Electrically, the LED Flashlight/Work Light (1) is quite easy to use...just press & release the black button on the front of its body once to activate flashlight mode, press & release it again to activate work light mode, and press & release it a third time to neutralise (deactivate) it.

Just like it reads on the backs of many shampoo (or shampiddle) bottles, "lather, rinse, repeat". In other words, pressing & releasing the button again activates flashlight mode.

To change the batteries in the LED Flashlight/Work Light (1), turn it upside-down. Between the center and bottom of the product, you'll see a battery door. Slide this door toward the bottom until it comes off, stow away aboard a space shuttle (the Enterprise would be preferable because it might have transporter technology; but the Atlantis will do in a pinch), wait until its orbit brings it somewhat in line with Jupiter, do an EVA (you *DID* remember to kype a space suit, didn't you?), and use a slingshot to shoot the battery door toward Jupiter...if you're extremely lucky, the battery door will enter the Jovian atmosphere in a few hundred thousand years and subsequently burn up...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

If necessary, remove the four used AAA cells from the compartment, and dispose of or recycle them as you see fit.

Insert four new AAA cells into the compartment, orienting them so that their flat-ends (-) negatives face the springs for them in the chambers.

Slide the battery door back on, and be done with it.
Aren't you glad you didn't sneak aboard a space shuttle and shoot that battery door into interplanetary space now?

The LED Flashlight/Work Light (1) is designed to be used as an occasional-use work light and flashlight (which also comes in a somewhat brittle-feeling plastic body), not used as a super sturdy "barrel-style" flashlight in a metal body that won't mind you abusing it. So I won't throw it against the wall, stomp on it, try to drown it in the {vulgar term for feces}bowl or the cistern, run over it, swing it against the concrete floor of a front porch, use a medium claw hammer to bash it open in order to check it for candiosity, fire it from the cannoñata (I guess I've been watching the TV program "Viva Piñata" too much again

- candiosity is usually checked with a laser-type device on a platform with a large readout (located at Piñata Central), a handheld wand that Langston Lickatoad uses, or a pack-of-cards-sized instrument that Fergy Fudgehog uses; and the cannoñata (also located at Piñata Central) is only used to shoot piñatas to piñata parties away from picturesque Piñata Island), send it to the Daystrom Institute for additional analysis, shoot it into a cosmic string fragment*, or inflict upon it punishments that a flashlight in a metal or sturdier plastic body may have inflicted upon it.

This product has a somewhat brittle feel to it; although having it fall to a concrete floor from chest-height may not cause breakage, I cannot guarantee that this will be the case. Since I only have one, and testing this theory might result in the product becoming busted and subsequently making additional comparisons & analyses no longer possible, I cannot actually test this.

The LED Flashlight/Work Light (1) is not very water (or other fluid, for that matter)-resistant.
If it fell in water and you suspect it got flooded, remove the battery door & batteries, dump out the water if necessary, and set it in a warm dry place for a day or so just to be sure it's completely dry inside before you use it again.

If it fell into seawater, got thrown into a glass of milk, if it fell in a root beer float, if it fell into a bowl of "soft-serv" ice cream, if somebody squirted a Massengill brand post-menstrual disposable douche or a Fleet brand disposable enema at it (and hit it with the douche or the enema), or if somebody or something got "pist off" at it and subsequently "pyst"

on it, rinse it out with fresh water before setting it out to dry. You don't want your LED Flashlight/Work Light (1) to smell like seaweed, sour milk, flowers, fresh butts, or rotten pee when you go to use it next. Besides, salt (from seawater, disposable douches, disposable enemas, or uranation), lactic acid (from moo juice), glycerol (from antifreeze), or sugar (from root beer & ice cream) can't be very good for the insides.

The 36 LEDs in the handle (used for work light mode) aren't on steadily; they're rapidly pulsed presumably to extend battery life. The duty cycle appears to be approx. 10%.

This is a wide viewing angle source, and if I've told you once, I've told you 31,054,500 times:
Wider viewing angles always, always, ALWAYS equal lower mcd values!

The video shows up when the URL is displayed as, "file not found" is entered, so I really don't know what's going on here.

This very brief video shows the PWM (Pulse Width Modulation) of the "work light" LEDs in the LED Flashlight/Work Light

See how the lights flicker rapidly instead of being steady-on?

O BOY! TWINKLING LIGHTS!
So very exciting!!
So heart-stopping!!!

TEST NOTES:
Test unit was purchased at a Grocery Outlet store in Federal Way WA. USA on 06-09-13.

UPDATE: 00-00-00

PROS:
Rather neat to look at whether on or off

NEUTRAL:
Because PWM is used, worklight isn't nearly as bright as it would be -- however this was a necessary evil that was used to extend the life of those small AAA cells

CONS:
Has a somewhat brittle, cheap feel to it
Getting the unit to function after battery change may be a bit fiddly
