Weather Ready 100 Hour LED Flashlight, retail $10.99 (Right Aid*)

Last updated 02-02-10

The Weather Ready 100 Hour LED Flashlight is a medium-sized handheld flashlight that features two 5mm Nichia white LEDs. These LEDs are focused by positive (magnifying) lenses moulded into the plastic end window. The light output by this flashlight is brighter than expected; these lenses probably have a great deal to do with that however.

It comes in a red plastic body with rubber armour around the bezel (head) and the tail. And it feeds from four AA cells (Energizer alkaline cells are included).

Feed the "Weather Ready 100 Hour LED Flashlight" its included batteries first, and THEN you can go to town.

To turn the flashlight on, slide the slide switch (located on the side of the barrel) forward (toward the LEDs).

To turn it off, slide the same switch toward the tail.

There is no momentary or "signalling" mode in this flashlight; please do not look for or expect to find one.

To change the batteries in the "Weather Ready 100 Hour LED Flashlight", unscrew & remove the bezel, and throw it as hard as you can into an open-pit copper or platinum mine so that a piece of heavy equipment (such as a Caterpillar or a front-end loader) runs over & destroys it......O WAIT!!! THAT'S THE GOOD PART!!! So just set it aside instead.
The flashlight could not be made to work regardless of what homebrew "fix" (ie. tape, aluminum foil, etc.) was used in the unlikely event you really did dispose of the bezel.

Tip the white plastic battery carriage out of the barrel and into your hand.
Remove and dispose of or recycle the used AA cells from this carriage if necessary.

Install two of the four new AA cells into the carriage, orienting them so that their flat-ends (-) negatives face the springs WITH NO YELLOW FOAM "DOUGHNUT" ON THEM. Install the other two with their nipple-ends (+) positives facing the springs with the yellow foam "doughnuts" on their ends.

Orient the battery carriage so that the end with the large metal disc on one end goes in first, and the other end, marked "ALIGN ARROW" is facing the switch.

Finally, screw the bezel back on.
Aren't you glad that you didn't huck that bezel into an open-pit mine now?

This battery changing procedure is a bit "fiddly", but I've seen worse.
I've even given fairly high ratings to flashlights that required tools such as screwdrivers, axes, hand grenades, and atomic bombs to change their batteries.

Unable to measure current use due to how the flashlight was constructed.

The "Weather Ready 100 Hour LED Flashlight" appears to be made from some pretty "tuff" "stuph", so I gave it "The Smack Test" - (I beat the living tweedle out of it - 10 whacks against the concrete floor of a porch {5 whacks each against the sides of the tailcap and bezel}) and found the expected damage: ***NONE!!!*** Actually, I expected to find (at minimum) some scuffing on the rubber armour protecting the tail & bezel, but found no damage or defacing at all.

The primary purpose of this 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 it strikes the concrete.

The "Weather Ready 100 Hour LED Flashlight" is weather- and splash-resistant, but it is not waterproof to the point of submersibility. It failed "The Suction Test" - not miserably, but some definite leakage was noted around the switch area. So please try not to drop it in creeks, rivers, ponds, lakes, oceansides, docksides, puddles of giraffe pee, slush piles, mud puddles, tubs, toilet bowls, cisterns, sinks, fishtanks, dog water dishes, or other places where water or water-like liquids might be found. A little rain or snow probably wouldn't hurt it though, so you need not be too concerned about using it in lightly bad weather.

If it fell in water and you suspect it got flooded, disassemble it as you would for a battery change, dump the water out of the barrel and bezel if necessary, and set the parts in a warm dry place for a day or so just to be sure it's completely dry inside before you reassemble and use it again.

If it fell into seawater or if somebody or something peed on it, douche all the parts out with fresh water before setting them out to dry. You don't want your flashlight to smell like seashells or uranation when you go to use it next. Besides, salt (from seawater or pee) can't be very good for the insides.

I do not yet have the target at my new Federal Way WA. USA location, so I shot this photograph at a distance of ~12 inches onto the white wall just to the right of my "BIG SCARY LASER" poster (sent by

A product's country of origin really does matter to some people, which is why I published it on this web page.

UPDATE: 02-02-10
I have given this light (plus two others) to my aunt; therefore I no longer have it at my disposal for future analyses or comparisons -- and the dreadful "" icon will now be appended to its listings on this website.

Reasonably durable construction
Decent intensity for a two-banger
Uses batteries that are common and relatively inexpen$ive

Battery changing can be a bit fiddly
