Where can I Get LED lights?
In 2009, we got excited once we heard that LED lights didn’t entice bugs. We do love LEDs for a number of factors currently - lengthy, longevity; reduced, low energy usage; and great, high-quality light. (additionally, the cool element.) The thought that they might also keep consitently the pests away felt too good to be true until we saw some credible sources explaining that LED lights emit little light when you look at the UV spectrum, and that it’s Ultraviolet light that attracts insects.
Lo and behold, the thesis hasn't passed the test of time. It is true that many LED lights try not to produce a significant number of UV light. But, while the spectral range of light made by LEDs can differ from light to light, as it happens that most do create a substantial level of blue light.
Blue light, as it happens, in addition appeals to insects. We emailed Andrei Alyokhin, an entomology professor at University of Maine, asking if he could “shed some light” in the matter. He reacted:“Insects are mostly drawn to UV light and blue light. They can not truly see red light. Warmth plays a minor, if any, role. So, insect attraction will depend on the wavelength of Light-emitting Diode light utilized by the home owners.”
… guaranteeing that, yes, white LEDs create a significant level of blue light, which also pulls insects - explaining the reason why, as some commenters regarding previous post noticed, many LEDs are not protected to molestation by people in the pest neighborhood.
This past week-end we tested the idea in the real life - particularly, outside a cabin in Northern Maine, where pests tend to be a-plenty - utilizing a Pharox 6 Watt LED bulb (this bulb is intended to replace a 60-watt incandescent bulb, although it only creates 360 lumens - less than half of exactly what a 60 watt incandescent would produce) and a GE show 10w, 400 lumen CFL (simply a slightly greater production versus Light-emitting Diode, it's promoted as a 40w replacement). We put the two light bulbs in accessories on either part of an exterior home. Lo and behold, both, unfortunately, did attract insects.
