" you have to do little retro wiring hearing this a solo eleven you know this person who work. Lighting out on the original architects design it was done ahead of the lighting plan. So anyway it's a little bit of not just and that that they will be this which will be back there the fetal be over here. And bill Halloween -- track lighting in the situation we get this terra -- yet again because of the -- we have with three different parts. We have this mounting bracket which we're going to install the toggle bolts right and then this -- Sleeves into the mounting brown okay -- is that -- hanging from. The terror cut down to a certain level and on this track lighting actually floats. Overhead like that right and it -- from. Back here with -- was threatened with all that credit card was there OK good I'm glad -- using toggle bolts into the hollow product that means it's. Very very. Secure space. Apparent effectiveness you know. The pre drilled out there. Now the key thing to keep in mind it's not just installing but how do you pick the right kind of fixture to do the right kind of lighting job. The learn more about that we went to the lightolier tech center. You designed this lighting display and that's normally we go visit the plant we look at heavy machinery does this kind of retreat it's a real."

" Clean place yes our corporate headquarters to -- we've created the tech center. To display a lot of techniques. Qualities functions and we'll also see some applications let's talk first about qualities of light what does that -- well there for basic qualities. Let's take a look at one of intensity watched the bonds go up in brightness yes. That's an important quality intensity of lighting secure distribution. Means basically how do we get -- out of the picture and into the room -- the -- has receded and now the floor Spirit right. Color is another important quality. Here around the perimeter we can see red green and blue the primary colors of light OK. The last. And often most important is changed like can be a motivational element. Whether it's changing seems like we're doing now or even moving from point a to point B through space okay. And you can even roll all those qualities together into Connecticut fact. So that we create. More like a movie marquee or even like nightclub like -- theatrical tonight yeah exactly OK let's take a look at another space. We're going to show you are effects hall. Hot and in here this is a terrific place to talk about four basic functions of light. OK first and foremost is visibility we need like to see light our way along the path that -- second is revealed form shape. There it is creating composition. Consider those -- spots kind of lead us into the right and last not least as mood or atmosphere. So now we can scroll through some quick scene changes and feel have a lighting changes. -- he's black walls you can't really I mean black walls absorb a lot of -- sure -- absorbing the -- like water to respond yet so we've gone from narrow to wide. And now we're going to -- light which is bouncing light off the ceiling -- terrific way to make a room feel right OK but again the walls are absorbing. So in this scene we're raising the chains. The lighting stays the same. And it's only by having white walls that the room really opens up and becomes a bright cheery place yes reflection. Now on these walls obviously you've got a variety of different. Materials representing textures right these are common materials. Some different paint finishes Stucco. Fabric brick wood and as you can see that -- effect similar to basic wall washers that essentially creates a flat effect. Pretty flat yet. He really want to make it jump out. Go to look grazing technique law grazing technique cause I thought this was called Washington law. It is wall watching let's say using -- grazing. The fact which means you basically keep the light fixture very close to the wall behind go to a directional source like apart. And march 16 so you can accomplish this with low voltage lighting. We'll look at that Stucco -- so everything really jumps out and comes alive and then what else are we doing in the next room. It's a terrific place to see some effects for accent lighting. Now we're gonna talk about lighting an object. Who like atmosphere for example. Right now we're lighting up from above so it's very dramatic effect. On the top but it's very flat underneath OK. Other ways we can lighted object our front lighting. This has to sources often if you have an object it's bigger than a bread basket you may need to lights to make it look its best okay. We can light from the side. You can see how the highlights and shadows change and also -- using some color filters here which are very subtle right. We can also back light it. And it's -- used car you know it's a magenta filters and a low voltage can spot okay and another very dramatic way to like something is from the side. You can see here you get along."
