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.

When a light switch or electrical outlet doesn’t function correctly, a professional electrician can trace this back to a variety of causes. First, it’s possible this non-functioning device was never connected to the wiring in your building. Secondly, the circuit affected by a switch or outlet may not be completed because of another component. For example, a switch may control an outlet which is unoccupied by a lamp or any other electrical device. Also, an outlet may be connected to a switch which is in the off position. A third cause might be related to a defective breaker, or a breaker which was tripped or turned off, but never switched back on. However, a fourth possibility may relate to a much larger problem.

Sometimes, a switch or outlet fails when it is damaged by arcing. If the arcing was caused by a connection to aluminum wiring, great potential hazards exist. If your home or building was constructed or renovated before 1972, or during the late sixties, it may contain aluminum wiring. Aluminum wiring was used legally during those years, but outlawed for installation in new homes, commercial buildings, remodels and renovations after it was identified with conditions which could lead to electrical fires.

Although aluminum wiring itself is generally no more hazardous than copper, its splices and connections with other metals present a real hazard because they can become corroded and begin arcing. Because arcing in these connections can lead to a fire within surrounding materials, aluminum wire was discontinued. However, many homes still contain aluminum wiring, and research conducted by the Consumer Product Safety Commission (CPSC) reveals that buildings with aluminum wiring pose a fire risk which is 55 times greater than the risks with similar structures wired with copper. So, if you discover an electrical outlet or switch which doesn’t appear to be functioning correctly, it’s possible this outlet or switch was damaged by a connection with aluminum wiring.

A home theatre system is the corner stone for any man cave. With the huge TV and massive speakers, it can make any movie seem like a reality. But to get that home theatre system perfect it requires organization and the right tools.An Expert Electrician can help get your home theatre system setup just the way you like it.

Home theatre systems can use a lot of power. When you have everything plugged in (the television, speakers, blu-ray player, gaming system) there is a lot of power that is required to keep it all going. Sometimes it is not as simple as plugging into the wall outlet and turning it all on. You want to ensure that the outlet is strong enough and the wires behind the wall can support the load. If your overload your outlet you could cause damage to your new electronics and home electrical system. Similarly, if you have too much load on a circuit, you could be risking electrical problems that could damage anything on that circuit or cause constant tripping in your breaker. When you have all your equipment prepared, have an expert electrician assess the output that the circuit and outlet will need. We can make the necessary upgrades to get you going.

One thing we have been encouraging everyone with lately is to have a surge protector on your appliances and electronics. There is no exception here. You have a lot invested in your home theatre system, so using surge protectors will add a barrier of safety to your expensive devices. Whether it is a power bar or a home surge protector, it is worth the investment.

One sign of a properly setup theatre system is the absence of visible cables. There can be several cables connected from one device to the next. This makes an eyesore if it is not properly sorted. When you have your equipment and the necessary wires, make a plan of where you would like everything to go. If you have difficulty mapping out your wires, call in the experts. We will help create a plan of action to place each and every wire. Keeping the wires organized and out of sight will make the system not only aesthetically pleasing, but also much easier to switch out and upgrade in the future.

It can be complicated setting up a home theatre system, but if you are organized and have a plan you will end up with an area all your friends will be jealous of.

If you’ve ever watched the show “Holmes on Homes” on HGTV, you’ve likely seen the problems associated with old or faulty wiring.  Mike Holmes tends to get very agitated by safety issues, and for good reason.  Each year, over 40,000 homes suffer fire damage due to home electrical problems.  These electrical fires account for hundreds of deaths and thousands of injuries.  And what’s the main culprit?  Old wiring!

If you live in a classic home built before 1940, chances are you have old wiring in the house.  You may have knob-and-tube or Romex wiring, both of which can become brittle over time.  The insulation dries out and starts to crumble, causing the inner wire to become exposed. The cloth insulation around the wire deteriorates with age and eventually becomes unsafe.

But perhaps one of the biggest threats of Romex and knob-and-tube wiring is that these types of wires aren’t grounded.  That means if one of your appliances shorts out, you could become the path to the ground for the electricity.

Even if your home is only 20 or 30 years old, you could still experience electrical problems at home due to a lack of capacity.  Most homes built more than 10 years ago are not designed to handle the amount of electronics we use today.  Think about it:  if your house was built in 1980, it was built before home PCs and laptops and HDTVs and surround sound and all of the other toys and gadgets we use today.  These appliances can draw a lot of power, and your current electrical wiring may not be up to the task.

If you own one of the one million houses in the DFW area that’s more than 20 years old, it’s a good idea to have a licensed electrician come out and take a look at the wiring.  He or she can make sure that your house will be safe and productive for many years.
