An absolutely FANTASTIC and INCREDIBLY cheap source ($5!!) of clean (low visible light output contamination) UVC light for a variety of purposes beyond sterilization of surfaces, most interestingly for the excitation of fluorescent minerals (see the three attached images - first image with manganocalcite, terlingua calcite, and willemite under normal visible light, then in fluorescing in darkness under the UVC from the Homedics sterilizer, then only the willemite and terlingua calcite phosphorescence in total darkness immediately after the UVC is switched off).
Most shortwave UV lights for this purpose cost 10-20 times as much as this device (they must have made thousands of these things in anticipation of high demand during COVID, but now that practically no one cares about that anymore they're clearly trying to dump them here at any cost - so if you're an amateur scientist, their loss is your gain!). Of course, the device has to be modified to defeat the safety interlock and allow it to be turned on while open - this is easy with any magnet (ALWAYS WEAR POLYCARBONATE GOGGLE UV EYE PROTECTION WHILE USING THE MODIFIED DEVICE!). It has two LED emitters which produce around 50 milliwatts of UVC light total at 280 nanometers (10 nanometers FWHM bandwidth of the peak) right on the edge of the UVB range, and VERY little visible light emission. Don't expect it to be a bright source of light like a flashlight, it's very evenly diffuse, NOT very bright, and will only work to induce visible fluorescence of minerals in darkness, but it does work!
Incidentally, the 280nm peak of UV emission (I personally measured it on a professional laboratory spectrometer) is WELL within the area of the germicidal effectiveness curve, even though it is some 25nm away from the typical mercury vapor lamp emission line at 255nm, and is definitely sterilizing surfaces exposed to its radiation very quickly. The device is well constructed, runs for 30 seconds after every power button press, can be reactivated again immediately, and recharges easily.
HIGHLY recommended for the UV enthusiast and amateur scientist into fluorescence photography (the light output can be even further cleaned with ZWB filters). And at only about 5 bucks, what do you have to lose??

Absolutely AWESOME - not for sanitizing phones, FOR FLUORESCENT MINERALS!!

Plegable y muy portable, para la desinfección de objetos de uso diario
Reviewed in Spain on August 2, 2020

Tiene un diseño muy original, estéticamente es bonito y práctico, con una superficie fácil de limpiar y además es plegable, con lo que podemos llevarlo incluso en el bolso o en una maleta si vamos de viaje, ya que es muy ligero de peso y no ocupa casi nada de espacio.
Respecto a su funcionamiento, es inalámbrico, se carga mediante un cable usb incluido, tan solo necesitaremos un adaptador de corriente como los que usamos para móviles y tabletas.
El dispositivo funciona de manera muy sencilla, simplemente lo desplegamos, abrimos su cremallera, e introducimos en el interior el objeto que queremos desinfectar. Cerramos bien la cremallera, pulsamos el botón de inicio y veremos que la lud led parpadeará en azul. Cuando pase 1 minuto, la luz se apagará, señal de que el objeto ya esta desinfectado y ya podemos extraerlo con total tranquilidad.
Aunque en principio pone que es para desinfectar móviles, en las instrucciones ya nos indican que también sirve para otros objetos, yo de hecho lo estoy usando para todo tipo de cosas que uso a diario: gafas, llaves, mascarillas, relojes, portamonedas y por supuesto, también el móvil, os aseguro que vale para todo esto y más, caben hasta las gafas, cosa que no ocurre con otros muchos desinfectadores portátiles.
Respecto a la seguridad de su uso, no hay que temer por los posibles efectos nocivos de la luz UV-C, pues este estuche cuenta con cierre de seguridad en la cremallera, y si el tirador de la cremallera no está situado magnéticamente en la posición de encendido, el aparato no se pone en marcha y la luz led parpadea en rojo para avisarnos.
En cuanto a la duración de la batería, esta muy bien puesto que podremos usarlo hasta 70 veces anntes de necesitar cargarlo de nuevo.
El unico aspecto que me resulta raro y al que me cuesta adaptarme es al hecho de que los botones parecen estar en la base del aparato, pues la cremallera esta en el lado contrario y una vez lo cierras tienes que girarlo para pulsar el botón y ver cuando termina el proceso de desinfección, pero como ya digo, no lo considero como algo negativo, es una simple cuestión de acostumbrarse a usarlo de esta manera.
En definitiva, me ha gustado este desinfectador de objetos porque es muy ligero, no es nada aparatoso, externamente es bonito y es sencillo de limpiar y además es muy seguro, por lo que considero que es un buen producto.
Ciertamente, no puedo saber seguro si es efectivo o no, espero que si lo sea y confío en una marca como Homedics, que siempre me ha dado buenos resultados, y ahora con el tema de los virus, pienso que no está de más aportar a nuestras rutinas diarias un extra de higiene y desinfección para estar más seguros y proteger la salud de nuestra familia.

Un dispositivo alla quale oggi, dopo il Covid-19, non si può rinunciare. Ottimo!

Questo é molto comodo, di buona qualità ed é abbastanza piccolo da portarlo in giro ma, al tempo stesso, abbastanza grande da contenere occhiali, chiavi e soprattutto smartphone.
Ho letto di qualcuno che aveva problemi con un telefono grande: io ho un OnePlus 6 da 6.3" circa e non ho assolutamente alcun problema! Ci entra perfettamente.
La zip credo sia l'unico punto "debole": ha un piccolo magnete che si attacca, una volta chiuso" al piccolo sensore che permette l'avvio della sterilizzazione. Il problema potrebbe essere proprio questo: se poi non si attacca più dopo tot tempo? Bisognerà trovare una soluzione e farlo tenere fermo ma questo rende meno sicuro l'apparecchio che dev'essere perfettamente chiuso.
Se non si attacca quel piccolo magnete tutto il processo non parte, il led lampeggerà sempre di rosso.
Una volta collegato il piccolo magnete vicino al sensore (é indicato nella descrizione ma lo mostro anche nel video che ho caricato) si può partire con il processo di sterilizzazione che dura circa 30 secondi. Ovviamente se é un telefono dovrete farlo per entrambi i lati quindi in poco più di un minuto avrete fatto.
Si può fare con qualsiasi cosa a patto che ci entri: occhiali, chiavi ecc... Pensavo fosse più piccolo ma, come scritto nel libretto, bisogna spingere il fondo per allargarlo e poi si può procedere con la sterilizzazione! Funziona anche senza "allargarlo" ma credo abbia meno effetto.
Ripeto, credo che tutti, dopo il Covid-19, debbano avere uno sterilizzatore UV in casa o portatile! Non si scherza di questi periodi e questo credo sia un'ottima scelta.
Consigliatissimo!
La batteria per ora regge ancora, l'ho caricato oggi (in circa un'ora, era arrivato già mezzo carico) e l'ho utilizzato almeno su 10 cose diverse e non ha dato segno di cedimento.
Ultima cosa che mi viene da ridire: non ha i led che indicano la carica residua! Praticamente non saprete quanta carica c'é fino a che non si scarica. Per il resto é ottimo davvero, soprattutto i materiali.
Consigliatissimo a tutti e per tutto! Spedizione velocissima, arrivato in 24h.
