This is a UVC (ultraviolet-C) disinfecting & sanitising unit. It's a fully self-contained, portable UVC radiation source. It uses four AA cells or a "wall-wart"-style AC adapter for power. It has a long, U-shaped 4-watt UVC tube to do its thing.

According to the furnished instructional material, it will kill 99.9% of bateria and viruses within just several seconds; plus it will deactivate (inactivate) spores that would otherwise mature into mould and mildoo...er...mildon't...I mean mildew.

It kills with ultraviolet C (shortwave UV) radiation, which disrupts DNA in living organisms; this also prevents dust mites & microbes from replicating.

It is intended to be totally portable, allowing you to disinfect such things as doorknobs, telephones, toliet seats (and other parts of the water closet as you deem necessary), dishes, faucet handles, baby bottles & nipples, typewriters, toothbrushes, computer keyboards, toys, cash registers, auto interiors, blankets, mattresses, shoes, etc. Yes, I did say "shoes" - it is stated in the furnished instructional materials that you can sanitise shoes with this product!!!)


To use the HygeniClean UVC Antibacterial Light Wand, feed it first (see directly below) or plug in the included AC adapter (also see directly below), and THEN you can commit 1st degree murder of microbes on your telephone or toliet seat.

On the underside of the unit (where the bulb is), you'll see a transparent purple cover over the bulb. Slide it toward the end approximately 0.7 inch, lift it off, and set it somewhere you'll be able to find it again later.

You'll see a large slide switch on the "handle"; slide it to the "ON" position. Now, turn the unit over so that the bulb faces down. You'll see a circular white button. Press and hold this button down for 4 seconds (timed on a clock wth a second hand on it) until the green light starts to flash, then release it. This "arms" the product.

Press & release this button again to turn the UVC fluoro bulb (tube) on.

Holding the unit so that the UVC tube is approximately 2.0" from the surface you're sanitising, slowly wave the unit horizontally (back and forth) over that surface, and keep slowly waving it for ten seconds to thirty seconds (five minutes for "shooz"). The unit turns off automatically after thirty seconds; if you wish to reactivate it at this point, just press & release that circular white button to get another 30 seconds.

When finished, slide the slide switch to the "OFF" position, and slide that transparent purple cover back over the bulb.

***YOU MUST NOT*** look directly at the fluorescent tube; although most prescription eyeglasses will block a significant portion of UVC radiation, I cannot guarantee that this will be the case.

The instructional material states that this unit will be effective when exposing surfaces with its radiation for just "several seconds" - this can vary from 10 seconds for mattresses, carpet, and upholstery to as long as 5 minutes for shoes.

To change the batteries, unclip & remove the battery door on the bottom of the "handle" of the unit, and set it aside.

Empty out the used AA cells into the garbage can (or the battery box if your community has a battery reclamation project in place).

Install four new AA cells, orienting them according to the polarity diagrams embossed into the inside bottom of each chamber.

Slide the battery door back on, and push in on it until it gently snaps into place.

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

You can also power this product with the included "wall-wart"-style AC adapter. Although the instructional material advises that you first remove the AA cells, I found that it is really not necessary for you to do so - a mechanical interlock activates when the AC adapter is plugged into the unit, removing the batteries from the circuit.

To use the AC adapter, plug the plug on the end of its cord into the female receptacle on the bottom of the "handle", and plug the larger part into any standard (in north America anyway) 110 volts to 130 volts AC 60Hz household receptacle (outlet).

The HygeniClean UVC Antibacterial Light Wand is meant to be used as a sanitising device in a dry area, not as a flashlight meant to be carried around, thrashed, trashed, and abused, so I won't try to drown it in the toliet tank, bash it against a steel rod or against the concrete floor of a patio, let my housemate's citty kats go to the litterbox on it, run over it with a 450lb Celebrity motorised wheelchair, stomp on it, use a large claw hammer in order to smash it open to check it for candiosity, fire it from the cannoņata (I guess I've been watching the TV program "Viva Piņata" too much again - candiosity is usually checked with a laser-type device on a platform with a large readout (located at Piņata Central), with a handheld wand that Langston Lickatoad uses, or with a pack-of-cards-sized device that Fergy Fudgehog uses; and the cannoņata (also located at Piņata Central) is only used to shoot piņatas to piņata parties away from picturesque Piņata Island), send it to the Daystrom Institute for additional analysis, or perform other indecencies on it that a flashlight might have to have performed on it. 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.

In fact, the photograph and spectrographic analyses below may be pretty much it.

The main "disinfecting" component here is the ultraviolet-C wavelength comprising mainly of the mercury line at 253.7nm.
A small amount of "vacuum UV" (wavelengths shorter than ~200nm) is produced; this is evident for the following reason:
A faint odour of ozone (O3) is evident near the bulb when the unit is in operation.

Because UVC and some "vacuum UV" wavelengths are produced, there's a fairly high likelihood that the tube envelope is made of quartz, rather than regular "light bulb glass". This is because the glass used in making light bulbs blocks virtually ***ALL*** UVC and ***ALL*** "vacuum UV" wavelengths; and since these wavelengths are allowed to pass (well, they SHOULD considering that this is a germicidal lamp!!!), I'm fairly certain that the tube material is something other than "light bulb glass".

This photograph depicts the light as being *SIGNIFICANTLY* brighter and more
greenish than it actually is. I do not have any instruments capable of measuring
radiation at wavelengths this short.

Spectrographic analysis
Spectrographic analysis of the UVC CCFT in this product.

Spectrographic analysis
Same as above; spectrometer's response band narrowed to a range of 250nm to 260nm to show the 253.7nm mercury line.

Spectrographic analysis
Same as above; spectrometer's response band narrowed to a range of 179nm to 380nm and deliberately "overexposed" to show alternate UV spectral lines.

Spectrographic analysis
Spectrographic analysis of the UVC CCFT in this product; plastic cover left in place to show that it really does absorb the deadly UVC radiation.

Spectrographic analysis
Same as above; spectrometer's input deliberately "overloaded" to show UV emission lines. Plastic cover left in place to show that it really does absorb the deadly UVC radiation.
