UV disinfection: LEDs versus lamps

Late last year, Laser Focus World's sister publication BioOptics World reported that according to BCC Research, "The global market for ultraviolet (UV) disinfection equipment was valued at $790 million in 2010 and is expected to reach $1.1 billion by 2013." Finally, the amazing benefits of light are being harnessed in everyday applications that improve health and the environment while reducing energy consumption and limiting the use of harmful chemicals. The BCC Research report points out, however, that although UV light disinfection for air, water, and surfaces has been practiced for more than 30 years, it has only achieved a signficant share of the disinfection market in the last decade. Why? Much of the delay probably has to do with increased research on the topic of UV disinfection and proof that it effectively kills viruses, pathogens, and even bed bugs, lice, and dust mites. Not to mention that lamp and LED prices continue to drop as performance improves.
