Lighting Systems

The following notes document the lights and gels we have available for the course in the Hunt A10A Media Lab.

Lights

Soraa LED 5000K

We have two sizes of LED bulbs at a 5000K color temperature:

The Soraa system includes magnetically attachable ‘Snap system’ diffusers, which we have available for both bulb sizes:

Soraa 00325 PAR20 25 degree diffuser
Soraa 00333 PAR20 10x36 degree diffuser
Soraa 01145 PAR30 25 degree diffuser
Soraa 01595 PAR30 10x36 degree diffuser

Cool Lights 5600K Chromakey (Green Screen)

We have a pair of these lights mounted on the ceiling to illuminate the green screen:

The chromakey backdrop paper roll is:

We also have small quantities of paint available upon request. This must be taken to a separate space for application, the A10A lab is not a suitable location for painting:

Dracast Portable Bi-Color LED 3200-5600K

We have a portable kit with three LED fixtures with adjustable color temperature:

Gels

We have gels for both color effects and color correction. The color effects are mostly saturated colors for producing highly stylized lighting effects. The color correction gels are intended for shifting the color temperature of a source.

Color Correction

The Cinegel 3202 and 3203 are good starting points for matching the 3200K ellipsoidals to the 5000K LEDs. See pages 8 and 9 of the Rosco Filter Facts guide linked below for a quick tutorial.

Product Name Description Mired Shift Transmission
Rosco 3202 Full Blue CTB Converts 3200K tungsten to 5500K daylight -131 36%
Rosco 3203 Three-Quarter Blue CTB Converts 3200K tungsten to 4700K daylight -100 41%

Procedures

  1. Always avoid unnecessary creasing and store all gels carefully in the provided envelopes. Gels are endlessly reusable if properly handled.
  2. If you need to trim a gel to size, please cut neatly to a standard size to allow future re-use.
  3. If you need to attach two gels, we have a special clear tape for the purpose. Please do not use this tape for anything else: Shurtape JLAR Clear to the Core Tape (Permacel J-LAR): 1 in. x 72 yds. (Clear)
  4. If you need to limit light, we have opaque metal foil: Black Foil Wrap
