For some odd reason, the LED's aren't attracting many bugs, most of my LED's are in the 2700k - 3000k range. I do see some around the pond lights, but having bugs around the pond is a good thing.





Wavelengths and color temperature:

The color that’s emitted from a light source is important because of its ability to attract bugs. As previously stated, shorter wavelengths (UV, blue, and green light) are more visible to bugs than longer wavelengths (yellow, orange, and red light) and, therefore, will attract them. Incandescent, compact fluorescent (CFL), halogen, and high-intensity discharge (HID) lights emit UV radiation that is attractive to bugs, and since certain types of bugs navigate by UV light from the sun and moon, a closer, brighter source of UV light can disrupt their orientation and draw them in. LEDs produce very little to no UV light, which makes them less visible to bugs. However, it is still possible for an LED bulb to produce shorter wavelengths of light (bluish white/cool white color), which will be more attractive to bugs. Therefore, when browsing for bug-resistant LED lights, it’s important to choose a bulb or fixture that emits more wavelengths that are above 550 nanometers, such as warm white, ultra warm white, or yellow lights.


Heat:

Incandescent, halogen, CFL, and HID bulbs waste most of the energy they consume—as much as 90 percent—in the form of heat. Bugs with thermal receptors can sense the heat released by these light sources. LED bulbs produce a minuscule amount of heat, which makes them less appealing to bugs.
