G/046 Lighting Rig

Power

The rig eats a lot of juice: It is fed from two 32amp Ceeform plugs on the wall (same wall as fire escape). According to the Mains Circuits page, both are on the Yellow Phase.

Dimmers

Pulsar status dimmers: (2 of)

• 8-pin Din analogue signal in, 0-10v
• With pre-heat (good for not shocking cold bulbs if they suddenly get turned on, this increases lamp life.
• 6 5amp channels each.
• IEC plugs on flying leads out.
• If they're buzzing, they're happy!
  • faults
    • Top dimmer channel 3, Likes to turn itself on to around 30% after a while. i.e. It's level can be raised, but not lowered beyond 30%. The time taken for this fault to appear can be minutes, or hours. It does not seem to be linked to heat - on 18/02/2010 the behaviour was observed when warm, and cold (given a break for 1/2 hour before retrying). This dimmer channel corresponds on the desk to what was "old channel I" - i.e. pre 18/02/2010 it would have been bottom dimmer channel 3..
    • Bottom dimmer channel 3, The transistor/triac looks fried and has continuity between the emitter and collector, also two medium-power 270 Ohm resistors have physically split. This dimmer channel corresponds on the desk to what was "old channel C" - i.e. pre 18/02/2010 it would have been top dimmer channel 3..

Eurolite DPX-405: (1 of)

• DMX512 control Via 3pin XLR. Pass Through.
• 4 5amp channels each.
• IEC sockets out.
• No Preheat.
• 13a Plug currently.

Double clunky 13a: (1 of)

• 2 13a channels each (MAX 2.5Kw each)
• 13a in and out for each channel
• Sliders / pots for control
• Max & min adjust (you'll need a flat screwdriver)
• Very useful on OB's. Don't hesitate to bring it!

Hardware

• On the ceiling is a home-made steel pipe frame, with some IWB's here and there (IWB's not connected).
• More pipe clamps, lamp clamps in box under lighting desk.

Cables

Usually found on top shelf in techie room

• 15a -> IEC
• Various lengths of 15a
• UK 13a ->15a adaptors (2 of)
  • Very useful on OB's

Patching

• IEC Panels feed the plugs on the ceiling.
• IEC leads from dimmers. MAX 5a (1Kw).

Lights

Furse fresnels: (2 of)

• Old fresnels.
• No barndoors
• TUNGSTEN

Selecon Asymetric floods: (2 of)

• Not old! - still incredibly popular as of 01/10
• Asymetric! not even spread of light. spread gets better, the further they are from the wall. Remember, big side at bottom.
• Use to light back walls evenly, rather than a large "splodge" of light at the top, and not much at the bottom.
• The above makes them very useful when doing Chroma keying work.
• Lamp access by flipping the catch on top - whole fornt of fixture is hinged to allow lamp change without re-focusing.
• Colourframe located by flipping open the cover at the top. Not the catch! Slide out colourframe from top.
• No Barndoors (selecon do still sell them though)
• TUNGSTEN 500w

Selecon Symetric Floods: (1 of)

• As Asymetric, but even.
• No colourframes.
• No Barndoors (selecon do still sell them though)
• TUNGSTEN 500w

Generic bar of 4 floods: (2 of)

• normal floodlights
• 3 functioning bulbs per bar.
• DIY colourframes from gridding - bend to suit...
• 300w / compartment
• very god for OB's

Generic floods: (3 of)

• normal floodlights
• DIY colourframes from gridding - bend to suit...
• 300w

Strand patt 123 Fresnels: (1 of)

• The funny egg shaped ones.
• No colourframes.
• T17 / T1 lamp.
• TUNGSTEN 1000w

Strand patt 743 Fresnels: (2 of)

• Adjustment control at rear, and behind barndoors.
• Rotating barndoors.
• Colourframes in cupboard.
• T19 / T11 lamp.
• TUNGSTEN 1000w

Polaris Quartzcolor Pole-Op Fresnels: (2 of)

• With rotating barndoors
• adjust Pan, Tilt & Beam Via knobs.
• Colourframes - the octagonal ones. in cupboard.
• Rotating barndoors.
• HALOGEN 1000w
• These are more "orange" than tungsten, so bear that in mind when colour balancing...

Par 64 Floor cans: (6 of)

• Black
• all with Gel frames
• MF lamps
• 500w Tungsten
• Please only use HT gels, as they make an awful stink!

Gels

Colours

• Blues
  • Lee 132 (medium blue)
  • Lee 118 (Light Blue)
    • Nice for set boards/uplighting...
  • Lee HT* 079 (just Blue)
  • Rosco 65 (pale blue)
  • Lee 117 (steel blue)
  • Lee 172 (Lagoon blue)
  • Unknown dark blue, marked as "199" (probably Lee regal blue)

  • Unkown purple (possibly congo blue lee 181, looks like UV - but isn't really)

• Greens (inc turquoises)
  • Unkown green (various & dark)
  • HT* 122 (Fern Green)
  • HT* 115 (Peacock Blue, yes it isn't really blue)
    • This works really well for backlighting set-boards.

  • Rosy Pink (not much)
  • Lee 148 (Bright Rose)
  • Lee 345 (Fuschia Pink)
    • This is stronger than you'd think

• Yellows
  • yellow straw(not much)

Diffusions & scrims

• Scrim - looks like tracing paper, but made of plastic and not nearly as flamable. Like gels, will melt if touching the glass of a flood. Use this to soften light - you can also put over only some of the fixture (called half scrim) to soften light e.g near to the source only. Very useful, but underused.

Colour Temperature Filters

• 1/2 CTB. Lee 202 or eqiv. Looks grey. decreases output of lower CT's (orangeyness reduction). Makes thing noticeably dimmer. ** tungsten (3200K) to daylight (4300K)
  • Mired Shift -78
• 1/4 CTB less strong CTB.
  • tungsten (3200K) to daylight (3600K)
  • Mired Shift -35

Signal

DMX

• Chamsys MagicDMX as control
• 120ohm terminator in back of last unit in DMX chain
  • currently Eurolite DPX-405
• UVI remux in construction.
