Overview
The Type 7251 MaxiCoop puts six PAR64 lamps behind a rectangular light box with room for two 36 × 48-inch filter frames. The difference a cloth makes is substantial. At 25 ft, six 1 kW FFR medium floods give 718 fc bare, 56 fc through Tough Spun, 46 fc through double 216 and 19 fc through double full grid cloth.

Replacement lamps
The globe table lists 1 kW tungsten and dichroic daylight PAR64s and 1.2 kW tungsten PAR64s. FFR medium-flood lamp reference. Mole includes the 1.2 kW GFE wide flood in the performance chart. The separate globe list ends at GFA.

Strengths and limitations
- Two slide-out frames make diffusion changes possible without changing all six globes.
- The MaxiCoop produces a much narrower field bare than it does through dense fabric. A matching centre reading alone cannot guarantee matching coverage.
Practical uses
For a rectangular skylight reflection over a car or countertop, fill the diffusion frame and watch its reflection from camera. When aiming the head from the side, check the long axis of the PAR beams. Mole’s bare chart assumes the globes are rotated for maximum field width.
Output and photometrics
Bare-head values are centre readings with the modules pointing straight ahead. Width and height in Mole’s chart follow the approximate half-intensity boundary. The diffusion tests cover the four 1 kW tungsten beam patterns. Select the actual material and lamp code in the calculator.
| Bare lamp at 25 ft | Centre (fc) | Field width × height |
|---|---|---|
| FFN | 1325 | 9.5 × 5.1 ft |
| FFP | 1175 | 12 × 5.3 ft |
| FFR | 718 | 12 × 5.3 ft |
| FFS | 230 | 24.1 × 11.3 ft |
| GFC | 2768 | 6.7 × 5 ft |
| GFB | 2033 | 7 × 5.3 ft |
| GFA | 900 | 12 × 8 ft |
| GFE | 400 | 20.8 × 10.7 ft |
Output through diffusion at 25 ft
| Lamp | Tough Spun (fc) | Double 216 (fc) | Double full grid (fc) |
|---|---|---|---|
| FFN | 67 | 50 | 20 |
| FFP | 67 | 50 | 20 |
| FFR | 56 | 46 | 19 |
| FFS | 43 | 40 | 18 |
Photometric & exposure calculator
Estimate centre-beam illumination and the corresponding camera aperture from this fixture’s published measurements.
Estimated output
Select a configuration to calculate.
Manufacturer readings are for the stated optic, colour setting and full output, measured at the beam centre. Values between measured distances are interpolated. Point-source values outside those distances are approximate inverse-square estimates; large sources cannot be reliably extrapolated and are limited to their measured range. Exposure uses frame rate, shutter angle, ISO and the selected incident-meter calibration. Only the optics and diffusion explicitly listed in the measurement are included; additional modifiers, bounce, beam edges, ambient light, ND filters and camera exposure-index differences are not accounted for. Confirm critical exposures on set with a meter. Photometric source
Power and controls
With six 120 V lamps the nominal load is 8.3 A per 1 kW lamp or 10 A per 1.2 kW lamp. Confirm the head connector and breakout at prep. An adapter that groups the feeds changes which lamps the board operator can control together.
Modifiers and mounting
Type 72518 is the accessory holder. The 72552 aluminized skirt encloses its sides and the 72529 filter frame measures 36 × 48 inches. Mole also lists Type 72551 adjustable solid extensions for cutting side spill.
Comparable fixture
A Super-Softlite makes its soft field by reflecting bare quartz lamps inside its hood. The MaxiCoop uses sealed PAR64 lamps and changes the field with the globes and material in the frame. 4 kW Super-Softlite.
The Type 20165 Six-Light Coop has six mogul-screw sockets and a six-circuit Socapex connection. The Type 7391 Maxi-Spacelite pairs six PAR64 lamps with a skirt and target.
Field coverage
Mole’s rental packages are listed by lamp wattage and include a skirt, holder and frame. The four-sided skirt extension is a separate rental item. Mole-Richardson rental catalogue.
Rental and used-fixture checks
Check whether the quote includes the holder, the aluminized skirt and both filter frames. Identify each cloth on the frames. A single layer of 216 is a different setup from the double 216 listed in Mole’s test.
