Question 1

Are Beacon Far-UVC continuous-clean lights safe for my family & pets?

Accepted Answer

Yes. Far UVC 222 has been proven safe for continuous exposure around people and pets in over 100 peer-reviewed studies. Unlike conventional UVC (254nm), which can damage skin and eyes, Far UVC 222's wavelength cannot penetrate the outer layer of skin or the tear film at threshold limit values.

Question 2

What Is Far-UV (222 nm)?

Accepted Answer

Far-UV (222 nm) is the only UV technology that is available today that can continuously and effectively disinfect air and surfaces safely when people are present.

As opposed to other forms of UV light, Far UV is unable to penetrate the outer layer of the human eye and skin making it safe for humans and animals. The photons produced by Far-UV lamps can deactivate and destroy 99.9% of airborne pathogens at the speed of light while constantly working in the background cleaning air and surfaces quietly and discreetly.

The desire for healthy indoor spaces is growing and is increasingly important. The continuous-clean air technology that Beacon's Far UV (222 nm) provides makes being inside exponentially safer, helping you and your loved ones to stay healthy wherever a Beacon is present.

Question 3

How is this different from regular UV light?

Accepted Answer

Great question. Not all UV light is the same—wavelength makes all the difference (just like visible light vs. X-rays).
The key difference
 • Regular UVC (254nm): Used in hospitals to disinfect empty rooms. Can cause skin burns and eye damage. Cannot be used around people.
 • Far UVC (222nm): Filtered to a specific wavelength that cannot penetrate human skin or eyes but still kills pathogens. Safe for occupied spaces. Far UVC 222 stops at the dead skin layer.
 • Sunlight UV: Contains UVA (315nm to 400nm) and UVB (280 to 315 nm). Penetrates into skin, causes sunburns and skin damage.

It's like the difference between a butter knife and a chef's knife. Same category (UV), completely different capabilities and safety profiles.

Question 4

Does it really work? How do I know it's cleaning my air & surfaces?

Accepted Answer

Yes, the science is definitive. Far UVC 222 inactivates up to 99.9%+ of airborne viruses and bacteria, including coronaviruses, influenza, MRSA, and E. coli—proven in both lab and real-world settings.

Evidence:
Columbia University study: 99.8% reduction of airborne virus in occupied office space
Hospital trials: Significant reduction in surgical site infections when Far UVC was used 
Testing on 20+ pathogens: Consistent high-kill rates across bacteria, viruses, and fungi
How you'll know it's working: While the cleaning is invisible (like Wi-Fi), many customers report:

• Healthier households
 • Reduced mold allergy symptoms
 • Improved air quality for family members 
 • Reduced odors

We offer third-party testing kits to measure before/after microbial levels if you want data-driven confirmation.

Question 5

How long does it take to clean a room?

Accepted Answer

Beacon works continuously, not in bursts—so 'cleaning time' works differently than traditional methods. Here's how it works:

• Initial disinfection. Within 1-30 minutes of turning on, pathogens begin being inactivated, depending on the pathogen and distance from device. 
 • Full room coverage. Most rooms reach optimal protection within 1-2 hours
 • Ongoing protection. Once running, Beacon provides 24/7 continuous disinfection—killing pathogens as they enter the space.

Compare this to cleaning and disinfection methods:

Air purifiers only clean air that passes through the filter; surfaces remain untouched, requires constant filter changes to work
Chemical sprays are a one-time kill; no ongoing protection, leave toxic residues
Beacon lights clean both air AND surfaces continuously, all day, every day

Best practice is to leave Beacon running in smart mode to cycle on and off for maximum protection.

Question 6

How many Beacons does my space need?

Accepted Answer

We generally recommend 1 Beacon for up to 1,000 square feet.

Question 7

Where should I place my Beacon for best results?

Accepted Answer

Beacon is designed to be plug-and-play simple. Here are our top placement tips and best locations:

✅ Living rooms/family rooms: Central location on a shelf or mounted on the wall 8+ feet off the ground
✅ Bedrooms: on a shelf or mounted on a wall 8+ feet off the ground
✅ Home offices: on a shelf or mounted on a wall 8+ feet off the ground
✅ Kitchens: On a shelf or mounted on a wall 8+ feet off the ground (high-traffic germ zone)
✅ Entryways/mudrooms: Where outside contaminants enter your home mount on wall 8 ft up

Tips for placement
 • Don't block the light
 • Elevate it --  8 feet off the ground covers the breathing zone and high-touch surfaces best
 • Placed near corners are better to maximize coverage
 • One device for up to every 1000 square feet in open areas or per room for maximum focused coverage (kitchen, mudroom for example)

Question 8

Do I need to replace filters or do maintenance?

Accepted Answer

No filters. No maintenance. No hassle. Beacon is truly the easiest air and surface cleaner.

• No filters to replace (unlike HEPA air purifiers that cost $100s/year)
 • No chemicals to refill 
 • No extra cleaning required

All you need to do is:
 • Plug it in
 • Leave it running
 • The lamp itself is rated for over 8,000+ hours of use (that's 1+ years of continuous operation). 
 • When it's time to replace the light bulb, we'll send you a reminder and a new bulb ships directly to you.

Question 9

How much do Beacon Far-UVC continuous-clean lights cost?

Accepted Answer

Depending on when you purchase (Black Friday or other seasonal promotions) the Beacon is typically averaging $750.  It uses $1.25-$1.50 per month in electricity.

When you compare this pricey air purifiers at around $1,100 which only partially clean the air, don't clean surfaces at all, and require up to $100 a year in filters to work properly Beacon is the most affordable continuous-disinfecting solution on the market.
