| The 1000 watt, 16 inch Ellipsoidal Reflector Floodlight (or Scoop) is generally used to light the backdrop (or cyc) and/or provide a general wash of light over the entire stage. (Cost of an Altman 16" Scoop with a 1000w lamp: $ 248) |

1. What are the two commonly available sizes of theatrical Ellipsoidal Reflector Floodlights (or Scoops)?
Twelve and sixteen inch.
2. What wattage lamps are used in each?
3. Where, and how, are Scoops traditionally used in the theatre?
Scoops are generally used to light the back drop (or cyc), provide a wash of down light over the entire stage or work lights for the load-in and load-out.
4. What is the difference between an Ellipsoidal Reflector Floodlight and a CYC "Light?"
A CYC Light is a large rectangular (12"x16") floodlight with a reflector designed to provide a smooth even wash of light across a vertical surface (Cyc) hung eight feet from the face of the light. Generally two to four units are placed within a giant yoke creating a huge strip light. (Cost of an Altman 3 section Sky Cyc w/ 1000w lamps: $ 831)
Four to six sections of 6' or 7'6" Border (or Strip) Lights, using 150 watt R40 or PAR38 lamps, are generally used to light the backdrop (or cyc) and/or provide a general wash of light over the entire stage.
(Cost of an Altman 6', 12 light Striplight w/ 12- 120w lamps: $ 426)
| 8' Border Light | 6' Border Light | Intensity w/ 250w lamp | |
| PAR38/FL | 17' x 25' | 17' x 18' | 64fc / circuit |
| PAR38/SP | 7' x 15' | 7' x 11' | 280fc / circuit |
5. What was the original function of the Border light?
To light the up stage scenery.
6. What are the two standard lengths of a Border Strip?
Six foot, 12 lamp and 7 1/2 foot, 15 lamp. Both of these units have lamps on 6" centers and are designed for the 120 watt BR-40 (or PAR38) lamps. Some rental houses also have available 8 foot, 12 lamp (for 300w PAR56) and 9 foot, 12 lamp (for 500w PAR64) units.
7. What type of lamps are used in Strip lights today?
Either Reflector lamps (such as the 120watt R-40FL) or 150 to 500 watt PAR lamps. Altman has also developed a 6'4" , 3 circuit, low profile strip light -- the ZipStrip -- around the 12 volt, 20 to 75 watt MR-16 lamp. Each color circuit contains 10- 12 volt lamps wired in series. (Cost of an Altman 6'3', 30 lamp ZipStrip 75w lamps: $ 1042)
8. What is a Source 4 MultiPAR?
A Source 4 MultiPAR is a striplight built around 3, 4, or 12 -- Source 4 PAR lamps. The 12 light unit, which is 8 1/2 feet long, can be wired in either 3- 4 lamp or 4- 3 lamp circuits. (Cost of an ETC - 8 1/2 foot MultiPAR-12 w/ 575w lamps: $ 2,440)
9. How many circuits are in the traditional Border light?
Three.
10. How, and where, are Strip lights used in the theatre?
Like scoops, Strip lights are generally used to light the back drop (or cyc), provide a wash of down light over the entire stage or work light for the load-in and load-out. The high wattage (300 and 500w) PAR strips have also been traditionally used to provide strong washes of back and down light for the Broadway style musical. Eleven of the 13 light pipes in Abe Fader's 1956 plot for My Fair Lady held 4 sections (32' to 36') of strip lights.
