There are times when you simply can’t or shouldn’t do certain repairs around your house. Not everybody is trained or cut out to take care of all the little jobs that arise. You need to hire a professional from time to time. One of the professionals you will likely need on occasion is a Glendale electrician. If you have never used an electrician or have had a bad experience in the past and are looking for a new one, how do you know what to look for? The team at The Electric Connection has been helping folks out for years and is here to help you as well. The following characteristics are what you should look for when you need to hire an electrician to take care of work around your home.

• Good reputation-ask your friends, neighbors and family members if they have used a particular company. What was their experience? Do some checking online as well. Angie’s List is a great place to start.

• Professional-an electrician that shows up at your door should look and act professional. A clean uniform is a good sign of a professional contractor. If you are bringing an electrician into your business, a professional appearance is very important.

• Licensed and bonded-this is an absolute must when hiring an electrician. Glendale residents should only allow contractors into their homes or businesses who have the proper licensing through the state as well as a bond to protect you in case there is any damage done to your home.

• Timely-Cable companies are often joked about because of their lack of timeliness, but it isn’t a laughing matter. You are busy and don’t have hours to sit around waiting for an electrician to show up. You need a company that can give you a set window and stick to it.

If you need an electrician, you can call The Electric Connection and find an electrician who meets all of these standards.

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.
