According to the latest scientific research, LED light may be key in the fight against malaria. A study published in The Royal Society found that all arthropods that were analysed, including mosquitoes, were significantly less attracted to customised LED lighting than ordinary fluorescent light bulbs. The research was carried out at the University of Southern California, the University of California, UCLA in Los Angeles and Philips Research in the Netherlands.
LED Lighting is Better for the Environment
The lead author of the study, Travis Longcore, concluded that the research is proof that customised LED lights are better for the environment and for people. He said: “The research provides proof in concept that LED lamps can be customized to avoid specific areas of the spectrum that could have adverse environmental consequences, while still providing light for indoor use. For places in the world where glass windows and screens are uncommon, reducing insect attraction to indoor lights is a big deal.”
Blue-Free LED Bulbs Attract Fewer Insects
Although any form of artificial light will of course attract more insects than total darkness, using LEDs could improve the problem and potentially reduce the number of cases of malaria in the process. The study compared insect reactions to the customized LED bulbs with traditional LED bulbs (with blue wavelengths), CFL bulbs and a control that used no bulb at all. The blue-free LED bulbs attracted 20% fewer insects than the other bulbs, even though they actually emitted a more intense light.
Malaria is a parasitic infection most common in developing regions of Africa. It kills approximately 584,000 people in 2013, and is spread by female mosquitoes. But by distributing these types of bulbs in areas where mosquito-borne diseases are common could help people light their homes at night, without the risk of attracting more insects.
UK Based LED Lighting Supplier
As an LED lighting supplier and installer in the UK, we think this new research is incredibly encouraging for the future success of fighting diseases such as malaria. People will always need to light their homes in developing countries, and the widespread use of lighting that attracts fewer insects can only be positive for the control and prevention of malaria.
