The ultraviolet spectral parameters are strictly controlled within the safe range. The Bug Zapper Lamp of Coospider adopts the 365-395 nanometer band, with an irradiance intensity of only 0.05W/m², which is much lower than the 1.0W/m² skin exposure limit stipulated by the International Commission on Non-Ionizing Radiation Protection (ICNIRP). According to the measured data from the German Federal Office for Radiation Protection (BfS) in 2024, the ultraviolet intensity at a distance of 30 centimeters from the equipment is equivalent to 1/80 of that under the shade of a tree on a sunny day. The effective radiation dose from continuous exposure for 8 hours is less than 30% of that from direct sunlight for 4 minutes. However, traditional mercury vapor mosquito killer lamps contain 254-nanometer short-wave ultraviolet light, and there is still a risk of corneal burns within a distance of 3 meters. In 2023, Japan reported 27 related medical accidents.
The photobiological safety certification is complete. The equipment has passed the IEC 62471 standard test and reached the risk-free level (RG0). Its LED light source does not contain toxic substances such as mercury and lead. The weighted radiant brightness of blue light hazard is only 1.2W/m²·sr, which is less than 10% of the screen brightness of a smart phone. Comparative studies show that the VOCs (such as chlorothrin) released by chemical mosquito repellent sprays can reach a concentration of 200μg/m³ indoors within one hour, which is 50 times higher than the WHO standard, while physical light sources completely avoid such health risks. The American Academy of Ophthalmology (AAO) recommends that when the hanging height of the equipment is greater than 1.5 meters, its potential impact on the retina of children can be ignored (risk probability < 0.001%).
Sensory interference has been scientifically quantified and verified. When the equipment is in operation, the noise value is ≤5 decibels (dB), which is 90% lower than the sound of a mosquito flying (55dB). The purple visible light of it has an intensity of only 3 lumens in the 400-500 nanometer band and has a weak impact on adaptability to the dark environment. The Sleep Laboratory of The Ohio State University confirmed that when the test subjects fell asleep 3 meters away from the device, the fluctuation rate of melatonin secretion was ±1.7%, which was not statistically different from the unexposed group (p>0.05). The 8-hour average concentration of PM2.5 produced by chemical mosquito repellents (such as mosquito coils) exceeded 35μg/m³, resulting in a 42% increase in complaints about respiratory discomfort.
The protection mechanism for special populations is clear. For patients with photosensitive diseases (such as lupus erythematosus), when they are active at a distance of 2 meters from the equipment, the exposure to ultraviolet rays is only 1/15 of the threshold for triggering symptoms. The 2025 WHO Health Report on the Elderly indicates that physical pest control methods reduce the risk of asthma attacks by 87% compared to chemical sprays. The device is also equipped with an intelligent light-sensing system: it automatically enhances the brightness when the ambient illuminance is less than 5 lux and reduces the power by 70% when it is greater than 50 lux, avoiding the superimposed stimulation with natural light.
The electromagnetic safety performance is excellent. The electric field intensity test shows that the magnetic field intensity on the surface of the equipment is less than 0.5μT (attenuates to 0.1μT at a distance of 1 meter), which is only 1/200 of that of a hair dryer and complies with the IEEE C95.1 human exposure standard. The electrical insulation layer reaches the double protection grade (Class II), with a leakage current of less than 0.1mA, which is 80% lower than the allowable value (0.5mA) for medical equipment. The zero accident record of the U.S. Consumer Product Safety Commission (CPSC) in the past three years attests to its reliability.
Ecological chain protection indirectly guarantees human health. The proportion of beneficial insects mistakenly killed by this equipment is less than 0.1%, while the mortality rate of pollinating insects caused by pesticide spraying reaches 22%. A 2024 study by the University of California indicates that for every additional 100,000 physical insecticidal lamps, the use of approximately 380 tons of pyretoid pesticides can be reduced, lowering the probability of drinking water sources exceeding pollution standards by 65%. Its ozone-free release characteristic (laboratory test concentration < 0.001ppm) also avoids accelerating the transformation of air pollutants and reduces the incidence of respiratory diseases in urban populations by approximately 3-8% (depending on the regional PM2.5 background value).
