Let's try that again...as soon as I started to open the package, I *knew* it wasn't a flashlight...

Feels like a trooooouuuble-liiiiiiight...feels like a TROOOOUUUUBLE-light!!!

This is the model EZXL3000 Extreme Light from E-Z Red. It is is a rechargeable LED "trouble light". There are no cords to fuss with, and no hot, dangerous, and fragile incandescent light bulbs to deal with. It comes in a sturdy ABS plastic body, and has a hook on it to allow you to hang it anywhere you might hang a traditional incandescent trouble light.

It has a rechargeable NiMH battery inside, and there are no cords to fuss with or trip over...o wait, I just said that.

Its light source is 30 5mm wide-angle white LEDs.


 SIZE



To use your spiffy new Extreme Light, charge it first (see directly below), and then you can go fix that car motor.

At the base of the illuminator head, on the underside of the product, there is a rocker switch. Rock this switch forward (toward the LEDs) to turn it on. Rock this switch backward (away from the LEDs) to turn it off.
NOTE: The light will *NOT* operate when the charger is plugged in.

The Extreme Light comes with a plastic hook on a swivel (already affixed to the product); you may hang the light from any surface this hook can "grab" having a maximum diameter of ~1.4" (assuming it is a cylindrical horizontal "pole" or pipe) or with a hole with an opening of no less than ~0.10" in diameter.
So you can hang it from the "catch" on automobile hoods if you're working on the motor, etc.

There are no disposable batteries to change in the Extreme Light; so I don't have to tell you which part to dash to the floor or ground and stomp on with old or used bowling shoes or which part to kick in the garden so the hungry praying mantids will think it's something to eat and subsequently strike at.

Simply plug the small end of the supplied transformer's cord into the charging receptacle on the bottom of the product's handle (protected by a rubber bung you'll need to lift away), and plug the large end into any standard (in north America anyway) 110 to 130 volts AC 60Hz receptacle.

A red LED on the left side of the illuminator head will come on when the charge cycle is complete.

It is advertised to have a 10 hour runtime per charge.

(Update 02-20-07): The red LED on the product itself does not come on at any time during the charge cycle, but an LED on the charger itself changes from red to green when the charge cycle is complete.

(Update 02-25-07): The red LED on the product comes on when it needs to be charged!!! I looked down at the meter (which indicated an intensity of ~15% of starting intensity), and happened to see the red LED on.
So it is in essence a "Feed me please!" light.

Battery disacharge analysis
Here is a battery discharge analysis.
As you can see, it operates for 1 hour 40 minutes (to 10% intensity) per charge.
I'm going to recharge the battery and try again; the advertising claims 10 hours.
Assuming I don't bump something and queer the test, the machine should poop out a chart on the day (late-morning or early-afternoon) of 02-23-07.

Battery disacharge analysis
Here is the second battery discharge analysis.
According to the second chart, it operates for 4 hours 4 minutes (to 10% intensity) per charge.
So I'm going to recharge the battery and try yet again.

As of 6:43am PST 02-24-07, I'm running another battery discharge analysis.
Again, assuming I don't bump something and queer the test, the machine should poop out another chart later today

Battery disacharge analysis
And here is the third battery discharge analysis.
The test was stopped at 10:45am PDT when the light output declined below 10%.
According to this third chart, it operates for ~3 hours 42 minutes (to 10% intensity) per charge.

I'll charge it back up and run a fourth & final battery discharge analysis tomorrow (02-25-07) morning.
The unit is now fully charged (5:17pm PST 02-24-07) so you will not see a spike from the battery being "hot" off the charger.

The fourth battery test was started at 6:58am PDT 02-25-07.
If this test goes anything like the last two, the machine should defecate (poop) out another chart before noon PST today.

Battery disacharge analysis
And here is the fourth battery discharge analysis.
The test was stopped at 10:52am PDT when the light output declined below 10%.
According to this fourth chart, it operates for ~3 hours 39 minutes (to 10% intensity) per charge.




Photograph of the front of the illuminator head, showing the LEDs and lens.

This is a work light, not a flashlight meant to be carried around, thrashed, trashed, and abused; so I won't try to drown it in the toilet, let my sister's kitty cats go to the bathroom on it, run over it with a 450lb Celebrity (motorised wheelchair), or perform other indecencies on it that a regular flashlight might have to go through. So this section of the web page will be significantly more bare than this section of the web page on a page about a flashlight that was born to be a flashlight.

I will however, be performing "The Smack Test" on it, because it might be dropped like an incandescent trouble light might be.

So I did just that (smacked it ten times against the concrete floor of a patio; five times against the side of the illuminator head and five times against the side of the tail), and found no damage whatsoever. I also stomped on it, and again, no damage was found.

The Extreme Light appears to be splatter-resistant at minimum, but it is *NOT* submersible.

Water, milk, diet Pepsi, coffee, urine, root beer, or other liquids could get inside. So please try not to drop it in creeks, rivers, ponds, lakes, oceansides, docksides, puddles of wild boar pee, glasses of milk, slush piles, mud puddles, tubs, root beer floats, toilet bowls, cisterns, sinks, cups of coffee, fishtanks, dog water dishes, old yucky wet mops, wall-mounted porcelain urinators, 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 moderately bad weather.

If it fell in water and you suspect it got flooded, shake as much water out of it as you can, and set it in a warm dry place for at least several days 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, fell in a root beer float, or if somebody or something peed on it, douche it off with fresh water before setting it out to dry. You don't want your Extreme Light to smell like seashells, sour milk, or urine when you go to use it next. Besides, salt (from seawater or #1), lactic acid (from moo juice), or sugar (from root beer & ice cream) can't be very good for the insides.

I do not have access to gasoline, oil, tranny fluid, brake fluid, antifreeze, or other automotive fluids, so I cannot test them on the exterior surfaces of the Extreme Light to see what effects they might have.

The window (or "lens" if you prefer, even though it does not focus or modify the light in any manner) is replaceable if it becomes seriously and permanently marred or broken.

Light is yellowish, not greenish as depicted in this photograph.
Measures 172,000mcd on a Meterman LM631 light meter.



Beam photograph (labelled as "whiter light") on the test target at 12".
Light is slightly bluish, not greenish as depicted in this photograph.
Measures 179,000mcd on a Meterman LM631 light meter.

These are wide-angle LEDs (est. 50), and if I've told you once, I've told you 100 times:
Wider viewing angles always, always, ALWAYS equal lower mcd values!!!!!!!!!

TEST NOTES:
Test units (three) were sent by www.ezred.com along with three of their Flip Lights on 02-15-07, and were received on the afternoon of 02-19-07.

The charger is labelled to output 4.2 volts DC at 1,000mA (1 amp).
Center of plug is (+) positive, outer can is (-) negative.

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


UPDATE: 03-28-07
I took it on the outdoor patio, and took the following photograph:



This photograph shows the light output from a distance of 8' 8".
That dark diagonal section at the lower right is the railing I set the camera on.

True, this doesn't show how well it would work under the hood of an automobile (as it was intended to be used), but it is the best I can do.


UPDATE: 03-30-07
I took all three of them to the outdoor patio, and took the following four photographs:


The unmarked unit.


The unit marked "yellowish light".


The unit marked "whiter light".


Just for "funzees", all three on together.

The first three photographs shows the light output from a distance of 8' 8".
That dark diagonal section at the lower right in each photograph is the railing I set the camera on.



UPDATE: 03-31-07

UPDATE: 01-29-12
After having used all three units during our recent extended blackout (power failure) of 104 hours, I noted that when the internal battery was well beyond its useful charge, some of the LEDs in them (yes, all three of them) were significantly dimmer (or dark altogether) than most of the others.
To wit:


Since this does not in any way affect the product's functionality during normal usage, there is absolutely no need to derate it at all.





PROS:
Never have to buy batteries or bubs for it
Appears to be at least reasonably durable
Includes AC charger


CONS:
Not submersible - but it wasn't meant to be used as a diving light
Runtime advertised is a little on the high side; four tests confirmed this
