2. PARTS OF A FIXTURE

3. Ellipsoidal Reflector Spotlight
Produces hard-edge, focusable beam
Shutters allow for framing of beam
May be used to project steel patterns (gobo), color patterns on glass (glass gobos) or color images on dichroic glass
Evenness of field depends on lamp position within reflector (bench focus)
Long through makes them suitable for FOH applications.
Labeled by either beam spread (26 deg) or lens width by focal length (6x12)

12. STRIP LIGHTS AND CYC LIGHTS
USED TO LIGHT DROPS AND CYCLORAMAS
PROVIDE EVEN WASH LIGHT FOR CYCS AND DROPS
USUALLY HUNG FROM BATTENS OR PLACED ON FLOOR (ground row)
COME IN MULTIPLY “CELLS” AND CONFIGUATIONS
USUALLY HEAVY AND LONG (2 man lift)
REFLECTOR SHAPE AND POSITION MATTER TO BEAM SPREAD

14. MOVING LIGHTS ALSO CALLED INTELLIGENT LIGHTS, AUTOMATED, OR MOVERS
2 TYPES - MOVING MIRROR AND MOVING YOKE
FIRST APPEARED IN 1979 ON GENESIS TOUR
USE ELECTRIC MOTORS TO FOCUS/POINT, CHANGE COLOR AND CHANGE TEMPLATES, ZOOM, AND EDGE/FOCUS
MOST USE DISCHARGE LAMPS, NO DIMMERS NEEDED

19. LED’s L.E.D.- LIGHT EMITTING DIODE
ELECTRONIC PART THAT EMITS A CERTAIN WAVE LENGTH OF LIGHT(COLOR) WHEN ELECTRICITY FLOWS THROUGH IT
USUALLY USED AS AN UPLIGHT,CYC, AND A WASH LIGHT
GETTING BRIGHTER AND DOING MORE EVERY DAY
USES LESS POWER
GENERATES LESS HEAT

26. PHOTOMETRICS
DATA USED TO DESCRIBE THE PERFORMANCE OF LIGHTING INSTRUMENTS, SPECIFICALLY THEIR INTENSITY AND BEAM SPREAD

27. COLOR TEMPERATURE
Color temperature is a characteristic of visible light, that has important applications in lighting. Color temperature is conventionally stated in the unit of absolute temperature, the kelvin, having the unit symbol K.
Color temperatures over 5,000K are called cool colors (blueish white), while lower color temperatures (2,700–3,000 K) are called warm colors (yellowish white through red).[1]

28. COLOR TEMPERATURE COLOR TEMP IS RELAVENT TO HOW COLORS AND PEOPLE LOOK
THE SUN IS ROUGHLY 5600k (COOL BLUE WHITE)
INDOOR LIGHT BULBS ARE APPROXIMATELY 3050k (WARM REDDISH WHITE)
FLOURESCENT BULBS ARE ROUGHLY 4400k (GREENISH WHITE)
MOVING LIGHT LAMPS ARE 5600k (COOL BLUE WHITE LIGHT)
STAGE LIGHTS ARE 3200k (WARM ORANGE WHITELIGHT)
COLOR TEMPERATURE HAS NOTHING TO DO WITH HOW HOT THE FIXTURE GETS
THE WAY WHITE LIGHT LOOKS IS RELATIVE TO ITS COLOR TEMPERATURE AND CAN BE COMPARED TO A RAINBOW, IT FOLLOWS TO SAME COLOR ORDER AS FAR AS THE QUALITY OF WHITE LIGHT

29. BASIC ELECTRICITY
ELECTRICITY IS THE FLOW OF AN ELECTRIC CHARGE/CURRENT
ELECTRICTY IS MEASEURED IN 4 CRITERIA:
VOLTAGE- PRESSURE OF ELECTRICTY IN A CIRCUIT - MEASURE OF ELECTRICAL POTENTIAL
AMPERAGE- AMOUNT OF ELECTRICY IN CIRCUIT - MEASURE OF ELECTRICAL CURRENT
RESISTANCE- THE RESISTANCE TO ELECTRIC FLOW IN A CURCUIT, MEASURED IN OHMS
WATT- HOW MUCH POWER IS USED
THE COMMON FORMULA FOR THIS IS:
WATTS=VOLTAGE x AMPERAGE

30. BASIC ELECTRICITY ELECTRICITY IS TRANSMITTED IN 2 WAYS AC OR DC
DC- DIRECT CURRENT
AC- ALTERNATING CURRENT
DC- IS BEST DESCRIBED AS BATTERY POWER
AC- IS THE ELECTRICITY IN YOUR HOME OR OFFICE
IN THE UNITED STATES WE USE 120/208V OR 277/480V POWER AT 60 HERTZ
MOST LIGHTING FIXTURES ARE EITHER 120V OR 208V
DO NOT TOUCH ANYTHING RATED 277V OR 480V

31. BASIC ELECTRICITY OHM’S LAW E=IR “E” IS VOLTAGE “I” IS AMPERAGE
“R” IS RESISTANCE
“W” OR “P” IS POWER(WATTS)
WHEN YOU KNOW 2 OF THESE VARIABLES YOU CAN FIGURE OUT WHAT YOU NEED TO KNOW
