Concerts, theater productions, film production, church services, large speaking venues... All of these require the same thing for proper execution: light!
But, what kind of light do they need? If you found this post, you probably know that you need more than a flash light for a correctly lit concert venue. You've also probably seen the lights, but do you know what they're called?
Parabolic Aluminized Reflector Lamps or PAR lights usually adorn the trusses of any major stage fixtures. You've probably seen the large Par light holders at arenas or the trusses above concert stages. These lights produce soft, flat light which allows the stage or set to look natural and the audience to see clearly.
James Thomas offers a wide range of Par lighting fixtures to adorn various truss systems. Basically, you can light the stage with absolute perfection with our selection because you have enough options to choose from. So, if you seek to light a stage, film set or whatever, consider James Thomas Engineering. You'll be sure to have the most complete selection with our stock!

Trusses in the Golden Gate Bridge
When we think of the Golden Gate Bridge, or suspension bridges in general, we normally don't think about trusses. We usually focus on the cables and suspension design. In fact, if you do a search on the Wikipedia entry for the Golden Gate Bridge, you will not find any use of the word "truss" or "truss systems" in the entire entry.
But look at the photos. What lines the entire bottom of the bridge? Yes, that is actually a giant truss. Any structure containing the connecting triangles for support is a truss. It's the perfect system because of the proper displacement of force within the object or structure.
I'd be hard-pressed to find a bridge that carries any substantial weight in the world that does not feature a truss. These things carry so much weight because they are the perfect design. Consider the molecular structure of a crystal: In this, we see six triangles brought together by nature to create a very strong (and beautiful) object. In essence, a crystal's structure comes from the formation of atomic sized carbon trusses, creating some of the strongest objects occurring in nature. Almost every molecular crystal structure features triangles in some way, in essence proving the perfect structural basis as the triangle.
So, keep this in mind as you go about building and utilizing truss systems. Truss design integrity is by no means accidental and even the objects that we don't think of for trusses (suspension bridges) tend to feature them in one way or another.
