While it might seem surprising, lighting for commercial buildings commonly accounts for as much as 35 percent of business overhead. The good news for business owners trying to cut costs is that commercial lighting technology is moving forward every day and modern lighting can provide the same or better quality lighting for less while improving energy efficiency. Upgrading your building’s lighting can take some of the strain off your building’s electrical system, but in order to get the most benefit from your new lights, you have to plan carefully!

It’s one thing to say “we want new lights for our building.” But it’s another thing entirely to say “we want new lights because we believe they will improve employee morale and productivity!” Before you implement a new lighting plan, consider the specific goals you have in mind for your new lights. These could range from the aforementioned productivity and morale improvements to reducing your carbon footprint and reducing your overhead costs.

If possible, try to find lighting schemes you like in other buildings that you think would work well for your building—this can give you a better idea of the lighting design you’re after. And of course, feel free to talk to the lighting design experts at Kolb Electric—we can help create the perfect lighting design for your building!

There are three specific categories of lighting, each of which serves a different purpose in your building:

A good lighting design will layer these three types of lighting, starting with ambient lighting, then task and accent lighting. Each type will require a different fixture.

The type of light fixture you use for a certain type of lighting can make a big difference when it comes to the efficiency and effectiveness of your lighting. Light fixtures are generally broken down into three categories:

This is the final post in our four-part series, "The Secret Guide for Super Moms” — tips, tricks and hacks for busy moms who need to know everything that’s happening in their house.

If you believe Pinterest, every home repair or improvement project can be a do-it-yourself job. Apparently, if every blog is to be believed, moms and dads around the country are remodeling bathrooms, rebuilding old houses and refurbishing vintage furniture -- and they do it all the time! And they look great doing it! And they have plenty of time to take lots of photos!

Maybe some people really are able to do it all (and write about it, too). Most of us are too busy and simply don’t have the training to do more than the basics around the house. When it comes to potentially dangerous repairs, a super mom knows that she needs a professional. When the time comes to fix, rewire or repair her home’s electrical needs, she knows she needs an electrician.

Electrical wiring is complicated and can be dangerous -- and it's tough to spot signs you need an electrician. An amateur electrical job may cause poor wire connections, overloaded circuits or faulty grounding. These situations are hazardous to you, your family and your property. While it may be tempting to try saving money by doing it yourself, or trusting your spouse or a friend to help, you're better off spending the money to have the job done right.

Let's take a fairly common scenario: your fuses keep blowing, or your circuit breakers keep tripping. Yes, you can keep replacing the fuses, but do you know whether they're the right type? Screwing in a 20- or 30-amp fuse as a replacement for a 15 is tempting—no electricians needed, right?—but now you've created a fire hazard by overloading your wiring. The smarter move: call a professional, certified electrician to wire a new circuit.

Like fuses, circuit breakers are meant to prevent circuit overload and the risk of fire, but we use much more electricity than people of our parents' or grandparents' generation. As you upgrade and add appliances and gadgets, you may need to upgrade your circuit breaker panels to adequately supply your home with power. Hire an electrician to do the job, not your brother-in-law who swears he did the same kind of work in the navy. The work is extremely complicated and should not be attempted by an amateur.

Turkey day is upon us, when relatives and friends descend from near and far to gobble stuffing, watch NFL football and reflect on the things they are thankful for. In the spirit of the holiday, make sure that by the end of the day you can still be grateful for your family's continued health and prosperity by following these Thanksgiving safety tips.

Careful with the Deep Fried Turkey 

Who needs a roaster? Adventuresome chefs who want to create a memorable Thanksgiving are turning to the deep fryer to cook the turkey. The process involves gallons of hot oil, so take precautions if you decide to use this method to prepare your bird:

With some prudence and awareness, you can enjoy your crispy bird safely. 

Beware Open Flames

Candles are a great way to provide atmosphere, but make sure they aren't close to any curtains or other flammable materials, and aren't in danger of getting knocked over. Never leave a burning candle unattended. The same goes for your gas burners. 

Clean up Your Clutter

Your guests might not be familiar with the idiosyncrasies of your house, like the children's cars scattered about the living room. Make sure any power cords and extensions cords aren't crossing the floor or walkway and posing potential trip hazards. 

Mind the Children

We expect adults to practice common sense, but children may not be so prudent. If you aren't used to having kids around, be aware that knives, candles, hot foods, liquids, matches and stoves might all prove irresistible to a curious youngster. Keep anything dangerous out of reach, and make sure the kids are supervised.

The jargon in the lighting world can often get mixed up. Color rending index (CRI) and color temperature are one of the most to be confused with each other. This post is going to clarify what the different between CRI and Color Temperature is so we can end this confusion.

Here is a short explanation why the CRI is more important to focus on before deciding for a color temperature. The color rendering index is the most important feature in certain applications as it determines the appearance of objects, faces and spaces. If this aspect is not relevant, the CRI can be as low as 60 or even 40.

The color rendering index (CRI) is a numeric evaluation of the light color accuracy with the reference of daylight (numbered 100). Sunlight and its broad spectrum will enable a person with normal vision to see 68 different colors in a color chart, but if the chart is illuminated by a light source of one wavelength only, each color from the color chart will appear as a different brightness of that one color. Some activities, such as walking or operating a vehicle, do not require the accurate perception of surface colors while others such as product selections in shops benefit from better color rendering features. Look at the application of the lighting installation. If the visual tasks are easy to perform the CRI doesn’t need to be high. In areas like offices, handcraft manufacturing and surgery, the requirements for visibility, contrast, visual guidance as well as face recognition need to be provided by a lighting system with a good CRI of >80 or even >90.

How much is the light color affecting the space? The term color temperature describes the temperature of objects by which they emit light, modeled through the “blackbody radiator”. When increasing the temperature of a “blackbody”, it starts to emit visible light in a continuous spectrum. The filament of a 60W incandescent lamp heats up to about 3000°F, as a result the lamp emits light with a color temperature of 3000K. Many of our artificial light sources do not create light by heating up a material until it glows like an incandescent lamps. Instead of creating a continuous spectrum, they generate an assortment of color emission lines. A blackbody color temperature cannot be directly given to this non-blackbody type of emission, generated by high intensity discharge and fluorescent lamps for example. For those light sources, a correlated color temperature (CCT) is indicated, based on the blackbody color temperature. A cool white fluorescent lamp has a CCT of about 5000K. The lamps light spectrum is different from a blackbody one but has the same temperature.

The light color influences the atmosphere in a space. The more cozy the ambiance the warmer the light color (lower color temperature) should be and the more dynamic the scene the cooler the light source (higher color temperature). The CRI is the most important factor to watch when choosing light sources. How good is the light source representing faces, colors and contrasts? The easier the visual task and perception the lower the CRI can be. The color temperature needs to be watched second, it is supporting the space’s atmosphere.

Conclusion

There you have it; an explanation of both the Color Rending Index and Color Temperature.
