Insect Vision: Ultraviolet, Color, and LED Light, Marianne Shockley Cruz and Rebecca Lindner from the University of Georgia’s Department of Entomology write, “Experimental work supports the idea that color perception exists in insects and that they are especially responsive to the shorter wavelengths of the visible spectrum and UV light.” Wavelengths are measured in nanometers, and shorter wavelengths of light (less than 550 nanometers) can indicate ultraviolet (UV), blue, or green colors. Cruz and Lindner also cite work that confirms the correlation between UV light from the sun and moon and how certain bugs navigate Earth. Another point to remember about bugs is that certain types, such as mosquitoes, are attracted to heat and have thermal receptors to help them find it. All of this information is helpful for determining why bugs flock to certain light sources.

The color that is 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 draw them closer. 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 LED lights that will attract less bugs, it’s important to choose a fixture that emits more wavelengths that are above 550 nanometers, such as warm white, ultra warm white, or yellow lights.

CCT) instead of nanometers, it’s easy to tell if the bulb will be more or less visible to bugs. CCT is measured in Kelvin (K), and different temperatures on the Kelvin scale represent different colors. An LED bulb with a CCT below 3600K will emit warm or ultra warm white light that’s not easily seen by bugs. Bulbs with CCTs of 3600K and above will emit natural or cool white light that is more likely to attract bugs.

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.

Bug lights are simply light bulbs with a yellow coating that decreases the color temperature of emitted light. Because of the coating, bulbs will emit a peak wavelength of light that is around 550-600 nanometers. However, you don’t need a yellow-coated bulb to reduce the presence of bugs. LED lights that emit warm-colored illumination, such as yellow malibu light bulbs for landscape applications, or From top left to bottom right: incandescent bug light, yellow LED strip lights, yellow LED malibu light bulb installed in landscape fixture, and gold-tint LED filament bulbs

Ecologist Michael Justice performed an experiment to determine the type of residential light that attracts the least amount of bugs. He used six lighting types inside of an insect trap each night during the summer. Justice also made efforts to equalize the effects of weather and the moon’s irradiance. His LED Z-Bug Bulb™ from NEBO is a bug zapper and an LED bulb in one. The bulb emits white illumination from its top and ultraviolet (UV) light from its caged center. The UV light attracts mosquitoes and other insects toward the bulb’s high-voltage electric grid and kills them on contact.

Because different types of bugs see different wavelengths, it is never guaranteed that an LED light won’t attract them. However, most bugs are attracted to short wavelengths of light and are especially drawn to UV light; they can see it better, and some use it for navigation. Bulbs that emit more short wavelengths of light (cool white/bluish color) will attract more bugs. Lights that emit a majority of longer wavelengths (yellow/orange/red colors) are less visible. Heat can also draw bugs into an area. LED lights produce little to no UV light and a minuscule amount heat, which makes them less attractive to bugs—so long as they emit longer wavelengths of light.

Wouldn’t it be nice to really step up your game this holiday season? This is the time of year when friends and family are sure to visit your home. Maybe it will be for an evening of fun and entertainment or maybe it will be for a lovely dinner. No matter what your plans are for the holidays, wouldn’t it be nice to have a little something extra to help set the scene in your home? A new chandelier is the perfect, functional idea. An electrician in Burbank, like those at The Electric Connection can get your new chandelier installed just in time for holiday entertaining.

Gathering in the sitting room for cocktails, games or good conversation is a great way to reconnect with old friends and family you haven’t been able to spend quite as much time as you would like with.

relatively high ceilings. Drive by any industrial park, warehouse, or factory, and walk inside and what you will see is a high bay light.

But walk into any factory or warehouse and you will see different styles and options, wattage’s and configurations. Traditional high bay fixtures that were once common place were Mercury Vapor, which were then replaced with High Pressure Sodium and Metal Halide bulbs. As new technologies were introduced, and old technologies became more common, the old HID bulbs were replaced with Induction and Fluorescent light sources. And more recently with the more wide spread approval and popularity of LED, we started to see conversions from these older technologies to the latest energy saving LED High Bays.

A High Bay Fixture, depending on the light source, can take on many forms and shapes. If you consider a Metal Halide or High Pressure Sodium fixture, they typically consist of a large heat sink block at the top of the fixture that typically houses the fixtures ballast. Below is an aluminum or acrylic dome and at the top of the dome is the HID bulb. These bulbs typically come in two wattage’s, 400 and 1000. 400 Watt Fixtures tend to be installed in ceiling heights no higher than 30 feet, 1000 watt fixtures are typically 40 feet or higher. Interestingly enough, spacing of lights is similar to the height they are located off the floor. A fixture installed at 20 feet from the floor is installed in a 20X20 pattern, 30 feet in a 30X30 pattern, 40 feet in a 40X40 pattern. Of the 3 type of HID bulbs, Metal Halide tends to be the best option. High Pressure Sodium Bulbs are very low on the temperature color and have the warehouse aisles have the ability to focus the light where it is needed. A light designed for a warehouse aisle is a lot different than a light designed for a gymnasium or a factory floor. In these spaces, a light that can flood the area evenly is important, in a warehouse aisle, a light that can light up the face of the shelves and the floor below is important. And when selecting energy efficient options, its just as important to understand the technology and what it is capable of doing. Adding controls to a T5 fluorescent fixture is a good idea only if the ballast is designed to handle that requirement and not lower the life expectancy of the bulbs. Motions sensors and daylight controls that dim the light output based on occupants and the amount of daylight available in the space. Technologies such as metal halide and high pressure sodium are not a good choice as these technologies are not good at dimming or turn on or off quickly. Fluorescent can dim, but you need special ballasts for them. So knowing what you want to do and may want to do is important at time of purchase, because not having the proper equipment or options could mean a costly lighting warehouses, factories, gyms and readily available through the utility companies, and mass adoption means the technology of LED had matured to the point where the questions and disbelief of past years have gone away.
