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.

The times, they are a-changin'. President Obama recently announced the details of his highly anticipated Clean Power Plan, a measure aimed at reducing the country's harmful fossil fuel emissions and limiting our contribution to climate change. The plan, when fully implemented, should reduce carbon emissions by 32 percent below 2005 levels by 2030. Read on to learn more about the Clean Power Plan and what it means for you.

Lower Prices at the Meter

The Clean Power Plan was developed by the Environmental Protection Agency, under the authority granted by the Clean Air Act. It imposes sharp limits on the types of energy production that power the nation's electrical work, but grants flexibility to states in how they act to meet those limits. In general, the plan encourages a shift away from burning coal during energy generation, while states have the option of upping their renewable energy production, using nuclear energy, increasing their efficiency or relying more on natural gas.

The good news for homeowners is that the plan is projected to decrease the bills you pay to power your residential electrical work. An analysis by the Natural Resources Defense Council found that the average home electricity bill could fall by as much as 8 percent, and consumers could save up to $37.4 billion overall in electricity by 2020. The rationale for the savings is that renewable fuel sources cost less to run over time once the initial infrastructure is in place. Also, the plan encourages investments in household energy efficiency, which means that you may come to be less reliant on your home electrical work without substantially changing your behavior.

Clean Air for Breathing

The Clean Power Plan has another ancillary effect that has nothing to do with electrical work: it should cut down on air pollution and create a healthier breathing environment. For example, while we rely on the ozone level high in the sky to block harmful sun rays, ozone at ground level is known by another name – smog. It is created when sunlight interacts with pollutants and can be very harmful to our health. The plan should reduce smog levels and provide us with cleaner air to breathe.

Furthermore, one of the biggest signs of climate change is unusually hot and dry weather in certain parts of the country, which can lead to out-of-control wildfires and harmful particulates that damage your lungs. Strange weather patterns have also been blamed for an increase in allergies this year. By slowing the pace of climate change and keeping harmful pollutants out of the air, the Clean Power Plan can help you breathe easy.

If you have any concerns about the effect the Clean Power Plan will have on your energy prices or electrical work, call a knowledgeable electrician today.

An Indoor Generator™ is a backup power system that is delivered to you fully charged.  The charge is held in the unit’s batteries, which will be available for immediate use the moment you need it.  Everything that requires power from wall outlets will lose its power in the case of an outage.  You can either be left without power or you can implement your home back up power system to stay up and running without worry.

A unit like this is important for people who live in areas where outages and power surges are common.  Even if these occurrences are rare, maintaining power through an outage will provide safety and value in the event that you do lose power.  Also, if you live in a condo or high-rise where gas generators are not allowed, you can still use a battery-powered unit like the Indoor Generator.  Finally, if you have valuable computer or medical equipment, a power outage or surge could destroy them.  Thankfully, an Indoor Generator can prevent this.

In many of our past electrical safety articles we have talked about electrical fires. The reason we warn homeowners so frequently about the threat of an electrical fire is because of the danger it poses to your home and your family’s lives. Electrical fires can result from poorly managed electrical wires or equipment and result in huge damages and health hazards. It’s important that you have taken the necessary steps to avoid this.

Electrical fires are fires that start as a result of electrical wires that are hot, overloaded, or sparking. Electrical wires run throughout your home, next to hundreds of feet of wood. If a circuit is overloaded or damaged it can become extremely hot and product a spark. If your circuit breaker does not detect this and fails to shut it off quickly the wires can heat up the surrounding wood structure and start a fire. The biggest problem with these types of fires is their location. The fire has now started behind the wall, out of sight. By the time the smoke is visible through outlets or vents, significant damage can already be done. By the time you notice the fire, call the fire department and they arrive to extinguish the fire, there will already by substantial damage to your home. This situation can be even worse at night while you and your family is sleeping. The fire can creep up on you and spread behind the walls before you notice. You may even find yourself in your home and unable to prevent the fire from overtaking the entire structure.

Some common causes of electrical fires are:

To prevent electrical fires ensure that your electrical circuit panel is properly organized and up to date. If your electrical panel is old and not properly organized, it will not detect overloads and do its job of protecting your home. We recommend having your home inspected every 10 years. Some problems you will not be able to identify on your own. Our electricians will be able to identify areas that need to be upgraded and brought up to code. There are some precautions that you can take on your own. Check on your appliances, electrical equipment, and extension cords to ensure they are not frayed or have exposed wiring. If you notice that one of your electrical devices is very old, it may be time to repair it. If you are not sure contact your local Expert Electric.
