Great question!
Fluorescent lighting in cold weather applications has been used for some time now. Typically you have cold weather ballast and cold weather rated lamps that have been used in freezer applications without a problem. They come in T12, T8 and T5 HO series these are the long skinny lamps that you see every where they come in two and four foot lengths. The problem occurs when one or more of the components are not listed for cold weather use.
CFL’s or compact fluorescents that you buy at your local hardware store to replace your incandescent light bulbs are not rated for cold weather use and cannot be used in cold weather applications due to their inability to start in cold weather.
LED lighting is unaffected by cold weather and is the recommended choice for optimum choice for energy efficiency. LED’s have draw backs as well. The number one drawback is cost LED’s cost more but the typical life expectancy is 50,000 hours which will make up for any cost differential and are more robust in nature. As the LED field expands and with consumers demanding more colors and brightness levels LED’s will be the one to bet on in the future.
In any case you will want to contact a local electrician to explain your options for your particular application as every lighting scenario is different.
As building costs grow, building owners and renters have been looking for cost saving strategies. One technique has been that the contractor not only builds the project, but also assists in its design. This technique offers some positive aspects to include a decrease in communication problems between the owner and contractor in regard to their needs, problem installation materials being detected in the design process rather than on the job, and less on the job changes.
Of all the symptoms that an electrical system can have, groups of lights that flicker are (in my opinion) the scariest. I suspect that you are getting some arcing somewhere. Arcing occurs when wire connections are close but not fully touching. The electric current jumps the gap, like lightning, and creates some heat. This heat could be minor, or it could be a serious problem, depending on how much current is jumping across the gap, and how wide the gap is.
Many construction teams use a portable generator to power tools and lights at a remote site. Sports officials may also bring in a portable generator to aid in night play or to run an electronic timer/scoreboard. Most commonly, residents and businesses left without power after a weather event will use a portable generator to keep vital appliances operating. A portable generator usually has enough power to keep a freezer, refrigerator, television and some lights working.
The need for surge protection products has increased dramatically and is expected to grow in the years ahead. Today’s businesses rely on computers and computer systems to support transaction activities essential to the success of the business. If the computer is down, most activities stop. The business comes to a grinding halt. Power irregularities such as surges and spikes create performance problems for the systems handling essential transactions and sensitive information.
Electric Vehicle Charging Systems: The SEC has established provisions for the future installation of electric vehicle charging equipment. Article 625.27 has been added to establish requirements for physical space in the service equipment to install a future disconnect for electric vehicle charging. The article also requires pre-planning where the panels and charging outlets would be installed. Consideration should also be given to routing raceways to the required parking areas. Article 220.57 identifies the additional electric vehicle load calculations to be added to the service demand loads. It is anticipated at this time that electric vehicles will be available in the Seattle area as early as the fall of 2010.
