Properly lighting a space or environment takes a little know-how. An important part of what will help make an educated decision is understanding correlated color temperature (CCT) and how it relates to the shade of white light that you will experience. Understanding CCT can help greatly with setting the tone or feel of a room.

Correlated color temperature (CCT) will tell you what hue and tone of white to expect from a specific bulb or fixture. CCT is measured in Kelvin (K), which is similar to degrees in Celsius. Different temperatures on the Kelvin scale represent different colors. For example, light at 2000K-3500K looks more orange/yellow and is called ultra warm or warm white, and as temperature increases in Kelvins, color changes to more of a “paper white” known as natural or neutral white (between 3500K and 5100K) and finally into a bluish-white known as cool white (5100K-20000K).

Using interweaving print technology, each image is printed on an LED panel light lens using eight rows of 180 ink nozzles that prevent any horizontal banding or visual imperfections. While the lens is being printed, a UV light cures and dries the image as it exits the printer. Printing time varies per lens size; a 2-foot-by-4-foot lens typically requires 15-17 minutes from start to finish.

Tackling a few home improvement and maintenance projects yourself can be a great way to save money. However, there are certain jobs better left to the professionals—for the sake of your safety and security and so that you aren’t wasting money on projects you may not be able to successfully complete on your own.

The key to keeping costs down and keeping your home or building safe and secure is knowing which jobs make good DIY projects and which require a little more technical expertise—like electrical work. Working with electricity requires special training and skill. It’s far too dangerous for a novice to learn by him or herself.

There are many reasons it’s important to hire a licensed, professional electrician rather than attempt DIY electrical wiring. If not performed correctly, a do-it-yourself electrical repair can be dangerous and ineffective and can even lead to:

At Kolb Electric, we want your home to be both efficient and safe. That’s why we employ only the most qualified licensed electricians to complete your electrical work. We understand the potential dangers and know how to work with electricity safely.

Last night, thousands of walkers and hundreds of runners in Edinburgh kicked off the Courtesy of NVA.org.uk

A bunch of research went in to creating this light up gear to meet the NVA’s head designer James Johnson’s following standards:

For the runners, the design team wanted something dramatic, so they ended up going with concentrated point source LEDs, which looked great both close and at a distance. The LEDs allowed them to mix color and adjust intensity of the lights remotely. The runners themselves had to be in tip-top shape, able to run 10 miles at a 9-10 minute pace in all kinds of weather. Therefore, as to not hinder them in their physical feat, the design team fashioned a webbing suit out of the LEDs, complete with a radio and battery pack. Check them out:

The only shortcoming of these suits was that they couldn’t be powered by the runner’s motion. After attempting to harvest energy via knee braces, they determined any impediment to the runner’s motion dramatically affects his or her performance.

For the walkers, Johnson and his team wanted to build something subtler, to provide adequate safety lighting, but not to distract from the viewing experience. They decided to go with staffs/walking sticks illuminated by a combination of electroluminescent tape, fiber optic fabric, and diffused and non-diffused LEDs. Each staff housed a micro-computer that would synch up the flashing patterns with the Orchestra’s score, with changes triggered by movement and altitude. And here they are:

The research team was able to use motion to generate power in this instance, since walking is a more leisurely, steadier movement. To harness the power of movement, two LEDs, two high power Neodymium magnets, and a copper coil go in the top of the staff, then as the walker strides along, striking the stick against the ground, one of the magnets oscillates through the coil, creating a small electrical current. One LED lights up when the magnet travels down, and the other when the magnet travels up, producing a twinkly effect.

The runners also received a smaller version of this staff in the form of a baton.
