well; not audio, but electronics. A tube, but not vacuum, against current problems

As you know, Wavebourn Audio Research Laboratories (Austin, TX) is known by high quality affordable audiophile power amplifiers and preamplifiers, and we commit to our customers as long as they need our products and support our business, but due to current problems we add to our line of production powerful, but safe electronic disinfection devices.

The lamp consumes 38W to cover the disinfection area up to 600 sq ft during 60 minutes, but protects you from being exposed to direct UV rays pausing in presence of a human being or a pet.

A radar shuts the UV-C lamp off as soon as somebody moves. It protects skin and eyes from exposition.

Ultraviolet light has been used for disinfection for over 40 years. Now researchers from Boston University and Signify (formerly Phillips) have confirmed its effectiveness against the latest problem.

In particular, Anthony Griffiths, Ph. D., Associate Professor of Microbiology at the NEIDL Laboratory of Boston University, revealed that 5mJ / cm2 UV-C dose deactivates 99% of the problem in 6 seconds. According to him, he and his team found that a dose of 22mJ / cm2 UV-C radiation reduced the amount of active problem by 99.9999% in 25 seconds.

This lamp emits 2 wavelenths, 185 and 254 nM, generating additionally ionized oxygen that kills bacteria and fungi in places where rays do not reach.

Upon request, bulbs that do not generate ozone can be installed. They have additions in the bulb that make kind of LPF that stops 185 nM that the oxygen absorbs.

We received first trial party of UV-C disinfection lamps. They are gorgeous! We are looking for dealers now in USA and Canada, while continuing working on their improvements. PM if interested!

$147/sample. 4,000 / month volumes will be available.

PM me if interested to participate, or to buy one sample.

In April I started my own research. UV-C is good for disinfection, but not user-friendly. It burns skin, eyes, if to stay long enough in rays. I decided to add some movement sensor. First of all, I tried PIR sensor, but it did not satisfy me. Sensitivity was unpredictable, delay was either too big, or false positives were too high.

Then I started searching what is already available and found a plant that produces almost what I need, selling to Europe and Asia. We discussed how to adjust the device to my specs, and now I have a trial party.

The lamp can be used in classrooms, restaurants, barbershops, and so on. If faster disinfection, or wider coverage is needed, 2 or more lamps can be used. I experimented with several of them in the same room, radars did not interfere with each other, all of sem sensed the movement perfectly.

However, all tubes that I have generate ozone, that is good if you have mold, or want to be sure to disinfect areas where rays do not reach. But for places that receive clients and need disinfection between them, ozone can cause problems, it needs time to settle down. A bit is fine, it smells like before thunder and lightning, but too much irritates throat and eyes. I plan to buy ozone-less tubes later.

Let's solve problems one by one. I understand what you mean.

For the dust I have also a solution. I installed inside of my Dometic air conditioner a 8W UV-C lamp without ozone, and 180 micron copper net with 15 kV on it, then another 180 micron net grounded. Let's see how dirty it will be after a month...
