Wel, thuh kompeny thatt maiks thuh QuiqLite XP440 kant spel "quick" orr "light" , but they DO produce a nice light that can be clipped into a shirt pocket, and which uses a wide-angle white LED to illuminate citations, ticket books, and other material which allows you to read and write in the dark; and also features a UV LED that causes otherwise invisible security features on ID cards and drivers licenses to fluoresce. As you can probably tell by my writing, the QuiqLite XP440 "ID Check" is marketed to police officers, ticket cops, military soldiers, pilots, doormen/bouncers, and other personnel where having a hands-free light to read or write with in the dark and check the validity of drivers licenses and ID cards would be advantageous.

I don't have a shirt with a pocket on the front
* , so I cannot test it in that fashion. Best I can do here is clip it on a collar.


The QuiqLite XP440 is ready to use as soon as you remove it from the package. The package isn't thermally welded, so you don't need razors, knives, or other sharp objects to open it. Just pop the two plastic tits on the top of the package by pulling the package apart at its top, and it will then swing open and you can get to your QuiqLite.

Press and release the button on the front of the QuiqLite to turn the white LED on, press & release it the same way again to turn the UV LED on, and press & release it again to turn it off. This button has a tactile sensation you can feel, and a clicking sound you can hear.
The QuiqLite XP440 has an automatic 5-minute auto shutoff feature built in. Five minutes after you turn the QuiqLite XP440 on, it shuts itself off with no intervention required on your part.
The auto-shutoff in this sample engages at exactly 7:24; I timed it on a clock with a second hand on it to arrive at this value.

The LED head is on an arm that can pivot up and down about 182 degrees when the product is clipped into your pocket.

Speaking of clips, the QuiqLite XP440 is equipped with a generous clip that allows you to clip into a pocket, or in my case, a collar. The pushbutton switch can be used right through your shirt fabric, so you do not need to remove the QuiqLite XP440 from your pocket in order to use it.

The XP440 also comes with a removeable clip called a "QuiqClip", which allows you to attach the QuiqLite to objects up to 1" thick - far thicker than objects it can be clipped to with the built-in clip.

To feed your QuiqLite XP440, turn it upside-down, slide the battery door off in the direction of the arrow, and set it aside.

Remove the two used CR2032 cells, and dispose of or recycle them as you see fit.

Place two new CR2032 cells in the chamber, flat-side (+) positive facing up. Replace the battery door, and there, you're done.

Battery life is advertised at "over 40 hours".

The QuiqLite XP440 seems reasonably durable, and should not become broken during normal use; and typical flashlight accidents should not be enough to damage or break it. After 10 whacks against a steel rod (five on the back, and five on the LED end), there was no damage found and the QuiqLite XP440 still works properly.

The only OBVIOUS damage mechanism that I can see is that the pivoting arm the LED is mounted on could become broken if it is forced beyond the ~180 degrees of its natural range. This is a wider range of motion than the original QuiqLite had (90); so damaging the unit in this fashion would be considerably less likely than it would be with the original QuiqLite.

The QuiqLite XP440 does not appear to be that water-resistant, but you should not have any problems if you use it in the rain or snow. If it fell into water or you suspect it got douched, take it apart (as you would for a battery change) and set the parts in a warm, dry place for a day or so. If it fell into seawater or if something peed on it, rinse the parts in fresh water before setting them out to dry. You don't want your QuiqLite XP440 to smell like seaweed or piss when you go to use it next. Salt (from seawater or pee) can't be very good for the insides anyway.

Since I don't have a shirt with a pocket, I clipped it to my collar, and snapped the photograph directly below:

As you can see, the QuiqLite XP440 fits on there and stays put until you need to use it.
In this picture, the QuiqLite XP440 was aimed downward about 90 degrees.

When you're not using your QuiqLite XP440 and have it out of your pocket, the LED arm fits down onto the body of the QuiqLite XP440, and has a latch of sorts. This latch emits soft but audible clicking sound and has a firm tactile sensation when the LED arm is pressed against the QuiqLite XP440's body. This helps to prevent the LED arm from swinging up and maybe even breaking when the QuiqLite XP440 is transported or stored. The pushbutton switch is still exposed, so you'll want to watch that. Remember though, the QuiqLite XP440 has a 5-7 minute automatic shutoff, so even if the switch does become accidentally activated, you won't end up wasting the batteries because the QuiqLite XP440 turns itself off.

The radiation from the UV LED appears to be approximately 385nm.

UV LED beam on the test target at ~12".

Beam photograph at ~18".
Measures 4,520mcd on a Meterman LM631 light meter.

As with the original QuiqLite, this is a wide-angle LED, and the low reading
you see is perfectly normal and is nothing whatsoever to be concerned about.

The ID number was blacked out to prevent a thief from doing something dishonourable with it.
My address is already plastered all over the net, so I do not mind showing it on this web page.

Spectrographic plot
Same as above (UVA LED); newer spectrometer software & settings used.
Spectrometer's response narrowed to a band between 340nm and 440nm to pinpoint peak wavelength; which appears to be ~376nm in this case.

Sample was sent to me by B.Q. of QuiqLite, and was received on 12-14-05.

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

UPDATE: 02-28-06
The UV portion of the XP440 works well in charging GITD (Glow In The Dark) materials, such as the buttons on one of my TV remote controls. So if you're a police officer, you can have fun with the XP440 while you're off-duty.

I have decided to rate this product 4 1/2 stars and place it in The Trophy Case on this website.

UPDATE: 10-22-08
B.K. of QuiqLite sent me another XP440 "I.D. Check" on 10-18-08; here are beam photographs & spectrographic analyses of the new model:

UPDATE: 11-04-08
* I found a shirt with a front pocket, so I was able to take a photograph of this product being used in the manner in which it was intended!!!
