Electrical engineers usually have a huge responsibility in implementing safe electrical conduits to ensure safety and efficiency in designs of power substations. Conduits are the means in which power cables run from the ground to the electrical equipment and appliances. In addition, conduits provide protection of medium-voltage circuits in the power substation. Examples of circuits that need this protection are collector circuits entering the substation and distribution circuits leaving the substation to feed residential and commercial power needs.

The term “light box” can mean a few different things, but from a lighting perspective it typically refers to a backlit display panel. Light boxes are most commonly used for advertisements or other commercial displays. You’ve probably seen them in trade show booths, restaurants, airports, nightclubs, offices, hotels, museum exhibits, and retail shops. That’s right, light boxes are everywhere.

One of the most common uses for light boxes is the commercial advertisement. You see these in large spaces like terminals or outdoors at bus stops. They capture the attention of passers-by and create lasting impressions. The light box pictured below is one of the biggest I’ve ever seen.

One of the most obvious places you’ll see light boxes are along the walls inside and outside of movie theaters. Sometimes lines of light boxes stretch incredible distances, advertising all the movies being shown in large theaters.

In fact, light boxes can be a fun addition to any home and can be used for as many purposes as you can imagine. Sure, you could illuminate a movie poster of your daughter’s favorite movie. But you could also make a custom sign saying whatever you want. I really like the light box below, created at home for home.

As part of our series on pop culture from 15 years ago – a continuing celebration of our 15th anniversary as Pegasus Lighting – here are 15 moments from March 1999 you may remember. Monica Lewinsky’s book on her affair with Bill Clinton goes on sale; the Dow Jones average beats 1000 for the first time; and The Matrix is released. Ah, the sweet 90s. Where were you?

1. Jar Jar Annoys Basically Everyone

At the Golden Raspberry Awards, better known as the Razzies, the award for Worst Supporting Actor went to Ahmed Best, who voiced the character Jar Jar Binks in STAR WARS: EPISODE 1, THE PHANTOM MENACE. Poor Jar Jar, you-sa not much appreciated by STAR WARS fans.

2. The Worst Picture of the Year

The Roth 401(k) combined elements of the Roth IRA and the traditional 401(k). In a traditional 401(k), you contribute income without paying taxes on it. You then pay taxes on the funds when you withdraw them during retirement. With the Roth 401(k), however, you pay the taxes upfront so that you can withdrawal funds tax-free during retirement.

 5. The Melissa Worm Attacks the Internet

At the end of March 1999, the Dow Jones Industrial Average closed above the 10,000 mark at 10,006.78. This was unprecedented! People made “DOW 10,000” hats and celebrated. In hindsight, people wonder whether that day represented the peak of our economy’s health up to that point or the peak of market excess that was responsible for the economic instability of the 2000s.

7. You Are the One, Neo

Legendary film director Steven Spielberg was once again named Best Director at the Academy Awards for SAVING PRIVATE RYAN. In fact, the director of early 80s movies like E.T. was on a real tear, just coming off of the JURASSIC PARK series and SCHINDLER’S LIST. He continues to direct great movies today.

9. Roberto Begnigni Is Exuberant 

Roberto Benigni won Best Actor for his role in LIFE IS BEAUTIFUL at the 1999 Academy Awards. His reaction immediately became more popular that the movie itself. I’ll have a glass of whatever he’s drinking!

10. Gwyneth Wins Best Actress

SHAKESPEARE IN LOVE was the most awarded film of the night of the Academy Awards. Perhaps the most touching award acceptance, though, was Gwyneth Paltrow’s. Try to watch her acceptance speech without getting teary. I dare you.

11. Lewinsky Tells All

In March, 1999, The Supreme Court of the United States upheld the murder convictions of Timothy McVeigh for the Oklahoma City bombing, which left too many dead and wounded to even go into detail here. It was a tragic and totally unnecessary crime, and the Supreme Court decision echoed the feelings of many Americans.

14. Stanley Leaves Us

On the day after we lost Stanley Kubrick, we lost another beloved American hero, the legendary baseball player Joe DiMaggio. His death was caused by lung cancer. He was 84 and sure saw America from an interesting point of view. The loss of this former star was felt all over the nation.

It’s fun to think back to these moments in the popular culture of 1999, even though not everything that happened was happy. Most of us lived through all these events and remember them well. Come back next month to see what we resurrect next.
