Yellow bug lights or bug away lights can usually be found in most hardware and home improvement stores.
What is a yellow bug light.
In effect the yellow bug light works by shifting the color temperature of the light lower on the spectrum to a point where it is nearly invisible to many flying insects.
Either way you can find them in fluorescent or cfl as well as incandescent which saves money and keeps on burning.
The reason a yellow light works at keeping insects away is because they simply are not attracted to it in the first place.
The yellow bug light bulb gives off amber yellow lighting illuminating your porch or patio while keeping insects at bay.
Bug lights take advantage of the difference between human and insect eyes in that many types of insects have trouble perceiving light with a lower color temperature.
A yellow light bulb used mainly outdoors that does not attract insects.
So incandescent bulbs attract the most bugs and it seems the higher the wattage the more bugs are attracted to the light.
Impressively the yellow hued leds turned out to be even better than bug lights bulbs on the market that claim to avoid attracting insects.
As the wavelength of a light source decreases its color temperature increases as according to wien s displacement law low color temperatures are red yellow and exhibit a long wavelength while high color temperatures are blue violet and exhibit a short wavelength.
The yellow bug lights are all about light pollution in the ecological sense.
According to the results by far the worst option for outdoor lighting was traditional incandescent bulbs while the best and least appealing to insects was a warm coloured led light those are the leds that produce a yellow orange hue rather than cool blue light.
If that isn t working for you they re available online.
Wavelength and color temperature have an inverse relationship which you can also see in the graph.
Insects see lights that radiate ultraviolet and blue light best which include black lights florescent and metal halide.
So low wattage led lamps could greatly reduce the impact of light pollution on insects.
Besides saving you money on energy costs these bulbs boast a longer lifespan to reduce the cost and hassle of renewing them.
How do they work.
These lamps come in a variety of wattages voltages and sizes.
