UV Mag-Lite Retrofits, retail $55.99 to ~$500.00* (http://store.advancedmart.com...)
Manufactured by Advancedmart (www.advancedmart.com)
Last updated 12-23-07




The 40xUV LED Mag is a 3-D Mag-Lite that has a LED UV source that is very resistant to drops, knocks, and bangs unlike fragile glass "flourescent" "lite" "blubs" . It uses an array of 40 5mm ultraviolet LEDs.

This product comes in three flavours: 365nm, 380nm, and 390nm.
All of them come with the Mag-Lite body; no need to hunt down a Mag or assemble the product yourself.

* Depending on wavelength; the 390nm one costs $55.99; the 365nm one costs ~$500.00.

These flashlights are regulated, meaning that they should provide a fairly consistent UV radiation over the life of the batteries, rather than insiduously dimming from the moment you turn them on like unregulated modules will.


SIZE



To get UV radiation, press the rubberised button on the side of the Mag-Lite's barrel until it clicks, and then release it. Press and release it the same way again to turn it off. This is continuous or hands-free mode.

For momentary or signalling mode, press the button more lightly (before it clicks) and hold it that way for as long as you need the UV radiation; releasing the button turns the light off.



To feed your Mag-Lite equipped with this "bulb", unscrew & remove the tailcap, gently place it on the ground, and kick it into the garden so the hungry, hungry praying mantids will think it's something yummy to eat and subsequently strike at it...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

Dump the dead D cells out of the barrel and throw them into a large, extra-heavy-duty garbage can (plastic OR metal) and kiss their sorry butts goodbye (we don't have a battery reclamation program here in California - please recycle them if you do).
Be sure to empty that garbage can every now and again; you don't want baby rats or Mourningcloak butterfly larvae.

Slide three new D cells into the barrel with the button-end (+) positive going in first.

Screw the tailcap firmly back on, and go about your business.
Aren't you glad you didn't kick that tailcap into the garden with all those hungry, hungry praying mantids now?


Here is what a praying mantis looks like.
I found this guy on the morning of 09-08-06 clinging to the basket of my scooter.

Current usage measures:
425mA (365nm)
651mA (380nm)
522mA (390nm)
All measurements were taken on my DMM's 4A scale.



These flashlights are loaners, and I'm sure its owner will want them back with no dings in their bezels or rat pellets or yukky old toliet water in their barrels. So I won't throw them against the wall, stomp on them, try to drown them in the {vulgar term for feces}bowl or the cistern, run over them, swing them against the concrete floor of a patio, bash them open to check them for candiosity, fire them from the cannonada (I guess I've been watching the TV program "Viva Piņata" too much again - candiosity is usually checked with a scanner-type device on a platform with a large readout, a handheld wand that Langston Lickatoad uses, or a pack-of-cards-sized device that Fergy Fudgehog uses; and the cannonada is only used to shoot piņatas to piņata parties away from Piņata Island), send them to the Daystrom Institute for additional analysis, or inflict upon them punishments that non-loaner flashlights may have inflicted upon them. So this section of these flashlights' web page will seem a bit more bare than this section of the web page on a page about a flashlight that is not a loaner sample.

As flashlights, the units are reasonably sturdy (as all Mag-Lites are), and are of a proven physical design. Mag Instruments (of which AdvancedMart has *no* affiliation!) has been making flashlights for years, and they have a long track record for durability.

The epoxy LED bodies do fluoresce (glow) very slightly, but it looks like most of the NUV radiation escapes and does what you purchased one of these UV radiation sources for in the first place.

Spectrographic plot
Spectrographic analysis of the LEDs in this UV radiation source (380nm unit).
Note that the peak emission appears to be approximately 395nm.


Spectrographic plot
Spectrographic analysis of the LEDs in this UV radiation source (390nm unit).
Note that the peak emission appears to be approximately 408nm.

In all three spectra, that hump in the very deep red region of the spectrum
is the second order reflection from the spectrometer grating, and may be disregarded.





TEST NOTES:
Test samples were sent by J.W. of Advancedmart on 11-05-07, and were received on the afternoon of 11-07-07. Two of these three UV radiation sources do have to be returned, therefore, that dreadful "*" icon will soon appear next to this listing on my website.


UPDATE: 12-23-07
The 365nm & 380nm units have been boxed up for return tomorrow (12-24-07); therefore, that dreadful "*" icon now appears next to their listings on this website.


PROS:
Reasonably sturdy host body
Some measure of water- and weather-resistance
Regulated, so intensity will not fall off immediately upon activation


CONS:
Large and fairly heavy when loaded with all those D cells
Wavelength is a bit on the long side; though not horribly so
