Very much unlike their incandescent and florescent predecessors, LED lights emit practically no ultraviolet wavelengths, and therefore have a drastically reduced attractive effect on insects. Whatever effect outdoor lighting may have on insects, should be showing precipitous declines over the past several years, as LEDs have become the dominant artificial light source.
- nobodyandproud 4y agoInsects are most attracted to UV, but they’re attracted to most of the visible (to human) spectrum. Just less so, which is why the recommendation is to use “warm” led to minimize insect attraction. Also, light usage hasn’t remained constant. LED’s lower power usage means that it enables more lighting, including solar powered (day charged) landscaping lights. So whereas owners would formerly only have one or two lights at low watts before, the reduced energy usage means that they sprinkle in another magnitude more with LED.
