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.

Using the right mixture of outdoor lighting in your front yard will enhance your home’s safety, security and beauty!

While it may seem like we can simply duplicate our backyard lighting scheme in the front of our homes, there are actually differing objectives to lighting your front yard. Lights in your front yard add security by deterring unwanted visitors while also adding ambient lighting to our landscape, and highlighting the architecture of our homes.

Sometimes it can seem that the light switch is connected to your wallet. But you don’t need to live with the lights out to keep your money to yourself. Here are some tips to help you make your lighting more efficient this year.

BC Hydro offers a simple comparison chart of the lighting technology currently available. Because of the wide range of brands and types of bulbs, be sure to do your homework before purchasing new bulbs for your home to make sure they will fit your needs. Energy Star also provides a helpful purchasing guide for when it comes to choose your bulb.

Don’t sweat the small stuff; Change it up, lighten your load and keep cool this summer with innovative and energy-efficient light source solutions and state-of-the-art ceiling fans and free standing fans.

1.  Stop baking in your kitchen!  Get rid of old incandescent and hot halogen bulbs.  Replace with cooler CFL’s (compact fluorescents) or LED’s (light-emitting diodes) in recessed and overhead fixtures. CFLs and LEDs** consume at least 75% less energy and emit 90% less heat.  Relamping with cooler bulbs will make a major difference in work areas of the home such as kitchens where oven, cook-top and dishwasher usage emit a great deal of heat.  Laundry rooms, too, can heat up pretty quickly when machines are in use, so update your illumination with cooler lamps. Also, switching to cooler bulbs in offices and hobby/work areas will vastly improve your ability to concentrate and keep cool.

2.  Shield yourself from sun streaming in through windows. Close the shades and curtains during peak daylight hours to keep the sun from fading your fine fabrics and overheating your rooms.

3.  Conserve energy and do not leave lights on haphazardly.  Consider automated heat and motion sensors to conveniently turn lights on and off.  Dimming ambient light sources adds an extra cool down option and helps save energy.  Brilliant and stylish cool new switches, automated fan and lighting controls provide the utmost in sophistication and design to revamp your home this summer!

4.  Opt for task light, and limit usage of general and accent light sources.  Task light includes focused reading lamps, uni-directional and adjustable recessed or track lights over work areas, and security lighting for safe navigation.  Although accent lamps enhance the beauty of your environment, save them for the times when you are entertaining or showcasing your home.

5. Beautify your environment and bask in the comfort of ceiling fans, wall fans and free-standing fans. Save on air-conditioning bills and keep cool by employing energy-efficient fans in rooms that are used most frequently.

♦When the air temperature is 78 degrees, your body will feel as if it is 72 degrees if you are seated under a ceiling fan operating at a low speed. Plentiful cooling options include innovations from Casablanca, Fanimation, Hunter, Kichler and Savoy House.

♦Purchase lamps, light fixtures and fans from a reputable dealer.  Top quality LED and CFL lamps are engineered to last and provide pleasant illumination.  Cheaper LED and CFL lamps may contain substandard elements; they may burn out prematurely and  illumination effects may be less pleasing. The best ceiling fans are engineered with motors that are guaranteed to last and work flawlessly for a lifetime of comfort.

Lighten Up, Cool Down and Revel in Summer 2013!

Bring on the summer heat, and power up the latest in sophisticated design and energy-saving innovation.  Pairing ceiling fans and air conditioners set at low fan settings offers the ultimate in comfort and energy-savings.

1.  ENERGY STARtm-rated fans:

2. The greater the angle of the blade, the more air circulation. Fan blade brackets should be positioned so the blades form a 12-15 degree angle for optimal circulation.

3.  The heart of every ceiling fan is the motor. Motors equipped with heavy-duty windings and sealed bearings that are permanently lubricated should work flawlessly for long periods of time.  Check out motor warranty information when comparing ceiling fans.

4.  A typical ceiling fan weighs between 15 and 50 pounds when fully assembled.  While many junction boxes may support that weight, a fan in operation exerts additional stresses. Be sure to upgrade to a proper junction box when replacing a light fixture with a ceiling fan.

5.  American Lighting Association (ALA)-member showrooms offer customizable fan products—decorator finishes, unique options such as hand-carved blades, custom light fixtures, ceiling medallions, and control systems, as well as installation tips and servicing advice.

It doesn’t feel like it yet, but fall is coming! Cooler weather and clearer nights are on the way; perfect time for some home hot tub relaxation. But when our electricians in Baltimore talk hot tubs, we have some concerns. These stem from various issues, but they can all mean one thing in the end: danger.

At Kolb Electric, your safety always comes first. Yes, even before our service (though you might argue that they go hand-in-hand; we would). If you’re considering a hot tub installation, or you’re just getting primed and ready to make use of the one you have, there are some factors we would like you to consider.

Looking for industry-leading electricians in Baltimore for your hot tub or home appliance wiring? Contact Kolb today!

The definition of the word faulty is “working badly or unreliably because of imperfections”, so when we’re talking wiring, faulty can mean old or damaged, or poorly installed. Both of these are equally dangerous and can lead to electric shock, electrocution, and fires! It’s serious business and we aim to help ensure you never deal with these potential threats.

So why are we so worried about hot tubs? Aside from the fact that they’re almost literally giant bathtubs with an electric current, once they’ve been installed many homeowners opt to never have the wiring inspected for water damage or replaced.

And even further beyond, some homeowners regard hot tub wiring as a DIY job. It’s really, really not. Wiring can get complex, and when you’re dealing with something as potentially volatile as electricity (especially when that electricity is surrounded you water!), even the tiniest mistake can become a harmful and even deadly issue.

So how do you get the glorious hot tub you’ve always dreamed of with none of the risks? Do these:

Hot tubs are made to be enjoyed, not worried over! When you’re ready for an installation, trust in the team at Kolb. Or if you’ve already got a hot tub, let our team make sure your system is working safely and effectively. Contact our experts today for the superior service and safety assurance you deserve!
