The JIL-Lite DD (also known as the JIL Intelli) is a small, keychain-sized LED flashlight that comes in a HAIII aluminum body, has a Luxeon III LED at the bottom of a smooth reflector, has a UCL(tm) (Ultra-Clear Lens) window (or "lens" if you prefer) protecting its LED and reflector, has three light levels and two signalling modes to choose from, and feeds from a single lithium CR2 cell nestled in its barrel to feed that LED with.

I think that was a comma-spliced sentence - I'm fairly certain my English teacher would {vulgar term for expelling feces} his pants if he reads this web page.

As far as I can determine, this may in fact be the JIL Intelli, not the JIL-Lite DD (Direct-Drive); even though it reads "DD(UP)" on the side of the barrel.

Actually, I *have* now confirmed that this is indeed the JIL Intelli; when I took it outside to perform "The Smack Test", I saw the inscription "Intelli" on its bezel.

For your information, "JIL" stands for the phrase, "Jesus is Light"; the name of the flashlight can also appear as JiL {note that the "i" is lowercase}.


 SIZE



The JIL-Lite DD comes with a CR2 cell already installed, so you can use it right away.

Turn the bezel (head) clockwise (as if tightening it) to turn it on.
Turn the bezel counterclockwise (as if loosening it) to turn it off.
This is high mode.

Turn the bezel clockwise to turn it back on in medium mode.
Turn the bezel counterclockwise to turn it off.

Turn the bezel clockwise to turn it back on in low mode.
Turn the bezel counterclockwise to turn it off.

Turn the bezel clockwise to turn it back on in S.O.S mode.
Turn the bezel counterclockwise to turn it off.

Turn the bezel clockwise to turn it back on in strobe mode.
Turn the bezel counterclockwise to turn it off.
Strobe rate is adjustable from ~4hz to ~15hz. The default value appears to be ~10hz
I have not yet figured out *HOW* to adjust the strobe rate, so please do not ask.

Like it reads on the back of many shampoop (or shampee) bottles, "lather, rinse, repeat". In other words, turning the bezel clockwise again turns it on in high mode.

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

*** VERY IMPORTANT!!! ***
I may very well be missing one or more modes here; the flashlight was not furnished with any instructional material.



To change the battery when necessary, unscrew and remove the bezel, dash it to the floor, look at it all funny, cock your head like a puppy that doesn't understand what it had just been told, and kick it into the closet...O WAIT!!! THAT'S THE GOOD PART!!! So just set it aside instead.

Tip the used CR2 cell out of the barrel and into your hand, and dispose of or recycle it as you see fit.

Insert a new CR2 cell, flat-end (-) negative first into the barrel.

Screw the bezel back on, and unscrew it slightly when your JIL-Lite springs to life.
Aren't you glad you didn't kick that bezel into the closet with all those boxes, overstuffed plastic bags, busted "vaccuummnnes", and piles of dirty wash now?

Unable to measure current usage due to how the product was constructed.

The flashlight appears to be ***very*** sturdy. Ordinary flashlight accidents will not be enough to do it in. I administered the smack test on it (ten whacks against the corner of a concrete stair; five whacks against the side of the tail and five whacks against the side of the bezel), and found absolutely NO damage. No optical or electrical malfunctions were detected either.

The JIL-Lite has a Type III hard anodized finish; I tried to cut through it with the blade of a Swiss army knife, and was not successful.
Would I really try to cut up a brand spanken new flashlight? You bet your sugar-coated toilet muscle (sweet patootie) I would, if it's in the name of science.

The JIL-Lite is water-resistant, and very possibly submersible to an unknown depth too. When I removed the bezel and performed that dreadful suction test on it, no air leakage was detected. There is a red O-ring between the bezel and the body; this should help seal out things like water, bird poop, mud, snow, uranation, and other liquids and semiliquids; keeping them outside the flashlight where they belong.

The unit is serialised; the serial number on mine is 1855.

The light output by the JIL-Lite is a pure white, with no red, pink, yellow, blue, purple, or "rotten octopus urine green" tint to it.
Not in the hotspot, not in the corona either.

This flashlight drives its Luxeon III at just 0.8 watts (the LED is significantly underdriven in this product); this should help the LED run cool and extend LED and battery life by a significant degree.

The dimmer functions appear to be PWM (Pulse Width Modulated); as I can observe flickering when the unit is switched to one of the dimmer levels and then waved about rapidly.

Measures 169,000mcd (high), 24,900mcd (medium), and 16,741mcd (low)
I used a primary (disposable) lithium CR2 cell for this measurement.

Measures 756,000mcd (high), 241,000mcd (medium), and 48,000mcd (low)
And I used a secondary (rechargeable) RCR2 cell for this measurement.

All these measurements were taken on a Meterman LM631 light meter.

TEST NOTES:
Test unit was furnished by JILLite and was received on 01-23-06.

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

As far as I am able to determine, the JIL-Lite website is in Korean; please use the translation matrix of your choosing to translate it to a language you can read.


UPDATE: 02-06-06

PROS:
Very tiny; small enough to put on a keychain
Bright little {vulgar slang term for one who initiates intercourse} for its size

Tough HAIII body will stay newer looking for longer


CONS:
Uses a battery type that may be difficulty to find and/or expen$ive in your local area; that's what lopped off that last 0.05 star from its rating
