What better way to celebrate Independence Day than to do so in Virginia, one of the first colonies to create talks of revolution against the British? Virginia had a huge rule in the American Revolution. In fact, our first president of the United States, George Washington, was from Virginia! Thomas Jefferson helped expressed reason for colonial independence from Great Britain by writing the Declaration of Independence. The last major battle of the Revolutionary War was fought in Yorktown, Virginia and that victory led to the end of the war.

Virginians have a lot to be proud about for their involvement in the American Revolution, so you know we love to celebrate July 4th big! Our fireworks are always over-the-top and our parades are the best in the country. If you’re planning to celebrate big this Independence Day, consider these activities to do the weekend of July 4th. Make this Independence Day a day to remember!

Museums have a hard line to walk, exhibiting items for public education and enjoyment while protecting those same collections from damage. Today’s museum also carry the additional weight of safeguarding the future of the environment – as well as their financial future – against the dangers of unnecessary energy consumption. What advancements have been made in preservation lighting technology to help accomplish these goals?

Light, including all three types: ultraviolet (UV), infrared, and visible light, causes permanent and irreversible damage to museum pieces. Cumulative and dependent on the intensity and duration of exposure, light affects chemical composition, physical structure, and, the appearance of a collection. There is no conservation treatment that can repair it. Light damage is forever.

Only complete darkness ensures conservation, since exposure to light in any form naturally breaks down items. However, keeping pieces locked away in the dark defeats the mission of the museum – sharing those works with the public. It is thus a museum’s dilemma to find a suitable solution that balances the best of both worlds, in addition to considering energy costs and the environmental impact of its lighting selection.  

In your search for preservation lighting, you will find that a great deal of lighting solutions involve UV (ultraviolet light), the most energetic and destructive form of light. These include natural light, fluorescents, HID, and tungsten halogen lighting. Fortunately, the effects of UV can be controlled with simple filters, offering a greater variety of lighting options. UV filters are hard plastic tubes or soft sleeves wrapped around bulbs/light sources, which filter and block up to 98 percent of UV light, preventing its damaging effects. NOTE: UV filters lose efficiency over time and must be replaced every eight-10 years.

Specific, detailed recommendations for preservation lighting levels based on your collection type can be found from various sources, including the Library of Congress, National Park Service, UNESCO, and more.

Since 1980, the GFCI building code requirements have expanded. Previously only used on construction sites, GFCI’s are now required in many different rooms of your home, especially those with moisture – washrooms, kitchens, pool areas, etc.

The GFCI monitors the input and output levels being passed through an outlet. If there is a slight difference in the current being transferred from the hot outlet to the neutral outlet, then the device will quickly cut off the power supply to prevent damage or injury. A GFCI can detect changes in current supply as minor as a few millamps. GFCI’s are a simply advancement in technology that could potentially save lives or prevent injury to your family.

If you need assistance installing a GFCI or determining the appropriate rooms to upgrade your outlet to a GFCI outlet, please contact Expert Electric. 604-681-8338
