Overview
The Type 5761 Six-Light Molepar is a 6 kW bank with three pivoting pairs of PAR64 lamps. All six lamps switch individually. With FFR medium floods at 50 ft, it delivers 325 fc at beam centre over a field roughly 26 ft wide. Switching to FFN very narrow spots takes the centre to 1,010 fc and cuts the width to just under 12 ft.

Replacement lamps
Mole-Richardson lists the following 1,000 W, 120 V lamps. Beam spread and colour depend on the globe installed.

Strengths and limitations
- A separate switch for each lamp lets the crew reduce output in steps while the lamps left on continue to run at full voltage.
- The whole pair swivels together. For a wider pattern, fan the three pairs and check the overlaps with a meter. The straight-ahead chart does not describe that configuration.
Practical uses
For a wide backing or a large bounce, choose the lamp spread before setting the stand position. At 30 ft a set of FFS wide floods covers 27 × 14 ft at 310 fc. FFP narrow spots at the same distance cover 8 × 5 ft at 2,320 fc. Rotating the lamps turns the long axis of the beam.
Output and photometrics
Centre-beam output in foot-candles for 6 matching 1,000 W, 120 V lamps. The columns point straight ahead and the lenses are turned for maximum horizontal width. The quoted field edges fall at approximately half the centre reading.
| PAR64 lamp | 20 ft | 30 ft | 40 ft | 50 ft | 75 ft | 100 ft | 150 ft |
|---|---|---|---|---|---|---|---|
| FFN · Very narrow spot | 6,300 | 2,800 | 1,575 | 1,010 | 450 | 250 | 110 |
| FFP · Narrow spot | 5,220 | 2,320 | 1,305 | 835 | 370 | 210 | 90 |
| FFR · Medium flood | 2,025 | 900 | 505 | 325 | 145 | 80 | 35 |
| FFS · Wide flood | 700 | 310 | 175 | 110 | 50 | 30 | No data |
| FGM · Narrow spot | 3,600 | 1,600 | 900 | 575 | 255 | 145 | 65 |
| FGN · Medium flood | 1,350 | 600 | 340 | 215 | 95 | 55 | 25 |
The manufacturer gives no 150 ft reading for the FFS wide flood. Its calculator range ends at 100 ft.

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
Six toggles on the head switch the lamps independently. Mole-Richardson specifies an attached 3 ft feed with a 60 A Bates MC257G plug. The head is rated 120/240 V AC or DC. The chart uses 120 V lamps, so confirm the lamp voltage as well as the connector on the rental package.
Optics and mounting
The Type 5769 two-leaf shields carry the optional Type 57614 diffuser frame, which measures 40 × 21½ in. The yoke has a removable 1⅛ in. steel pin. The manufacturer illustrates the fixture on a Type 41494 senior stand.
Comparable fixture
The Nine-Light Molefay has nine smaller PAR36 positions. The 6 kW Molepar uses 1 kW PAR64 globes, so the two fixtures need different lamp cases even though their maximum wattages are close. Nine-Light Molefay (Type 5541).
Field coverage and further reading
Lights On Kansas City lists this head as a “Par Brute” and lists the available 1 kW PAR globe spreads separately, from very narrow to wide. Lights On Kansas City tungsten inventory.
Rental and used-fixture checks
Check the code stamped on each of the six lamps. A mixture of spots and floods can look alike from the back of the head and gives a different pattern from the chart. Ask whether both shield assemblies are included if the job calls for the diffuser frame.
