If 2020 taught us anything, it was the importance of cleanliness around the house. More than ever, people have taken to disinfecting their surfaces and cleaning areas that might have been neglected before. LIFX has sought to meet this need with its new LIFX Clean lamps – smart bulbs with HEV LEDs that help kill bacteria. Now, they’re finally available for pre-order here in the US after initially launching overseas in a few markets.
This type of light is capable of destroying bacteria in the home without endangering you or your family. Users can activate this setting by selecting the cleaning cycle timer. HEV, or “high energy visible” light helps kill bacteria while remaining safe for plants, pets, and your skin.
At the time of their announcement, LIFX Clean lamps were still pending approval in the United States. The devices have since received that approval, but have also undergone another round of rigorous testing – with interesting and promising results.
According to LIFX, LIFX Clean can kill over 90% of S. aureus and E. coli bacteria depending on how far the bulb is from the surface and how long it is on.
Unlike high power UVC light, HEV takes longer to clean. The trade-off is improved security. When placed 1.3 meters from a surface, the lights killed 90.32% of E. coli bacteria and 20.57% of S. aureus after two hours. The amount of bacteria killed increases dramatically over time. After 1 hour, the lights killed 99.54% of E. coli bacteria and 98.67% of S. aureus bacteria.
Efficiency decreases with distance. At 4 feet from the surface, 12 hours resulted in only 84.62% removal of E. Coli and 73% elimination of S. aureus. Still, these results are promising – especially with a device that is literally tuned and forgotten.
It is perfect for cleaning phones, cutting boards, toothbrush holders, etc. Replacing light bulbs in the bathroom or installing dedicated lights in the kitchen can help keep those spaces clean, especially given the amount of bacterial growth in these two rooms.
Pre-orders start today in the US, with a single bulb starting at $ 70.
Note that all of these tests only applied to bacteria. It is not known whether or not lights have an effect on viruses.
