Conventional Fixtures:
Conventional Fixtures:
Parcan – Creates an intense beam of directional light they tend to be very intense and use 15 amp to power and are dimmable, you can also add filters (Gels) into these fixtures.
Par 16 (Birdies) - These fixtures tend to be used as footlights but are also helpful on set pieces as they are lightweight and small, filters can also be used for this fixture. A smaller version of a par can.
Fresnel - This fixture provides a wash and the Lense used in this fixture is the same as what a lighthouse would use you can change the size of the wash and add filters. You can change the size of the beam of this fixture by moving the bulb inside
Profile - Profile fixtures contain two lenses inside them and shutters controlling the beam of the fixture and you can use this to create corridors of light. You can control the edge of the beam by making it either soft or hard-edged you can do this by moving the Lense, these fixtures can also use Gels to change the color. These fixtures are perfect for lighting actors they have 2 lenses and can change the shape of the beam and if its hard or soft edged
Flood - This fixture provides a large wash of light, and gels can be used in the fixture.
Four Cell flood (Batten) - This fixture is primarily used for washes and can integrate gels where you could have an RGB and could use this to do additive mixing to create different colours.

Lighting Chain For Conventional Fixtures:
For a Conventional fixture to work and be able to be operated the desk needs power and also the dimmers/beta pack will also need hard power.
The desk is where the chain starts and after this, a DMX will need to be run from the desk to the dimmers, the DMX sends a signal to the dimmers that then after this the dimmers will transfer power to the fixture with usually a 15amp cable but can also be 16amp.
Each dimmer has 6 channels and each channel has two 15 amp sockets.
Rigging Timelapse
Rigging Prossess:
To rig a fixture firstly you need to check everything is safe with the fixture and that there is no damaged cables for the fixture and that it has the correct safety bond on.
After this you need to make sure the right safety equipment this could include your steal caps rigging gloves etc.
You must have someone footing the ladder with a hard hat on and have 3 points of contact on the ladder for whoever's going up.
​
After you would connect the G clamp to the rig and tighten the clamp and connect your safety bond after the cable for the fixture should come from the bottom of the fixture you need to make sure the cable is going to be safe and not get burned or damaged.
You would then focus the fixture however you would want it to be.
​
Distro (Power Distribution Box):
A Distro is a power distribution box it is a method of distributing an electrical circuit from a single input usually 63 Amp source to multiple output devices in the branch circuit using soka-pex cables to do so converting the power into 16amp to power conventional fixtures.
​
The Distro is controlled by DMX and is patched on the back of the distro using IEC cables and it is patched 1 to 1
