Overview
The 12-Light Moleeno packs twelve 1 kW PAR64 lamps into three columns of four. Each column pivots, and the lamps rotate in their retainers. From the same 100 ft position, a set of FFN very narrow spots puts 538 fc at beam centre. A set of FFS wide floods spreads the light across 90 ft and gives 53 fc at centre.

Strengths and limitations
- The three columns can converge on a distant mark or fan across a backing. The published figures apply with all three aimed straight ahead.
- Lamp choice changes both level and spread. At 100 ft the wide floods cover about 90 × 48.7 ft within the half-intensity boundary. The very narrow spots cover 23.3 × 15.3 ft.
Practical uses
For a night exterior, compare the width of the action to the beam at the intended throw. At 50 ft, FFR medium floods cover about 25.8 × 12.5 ft at 645 fc. FFS wide floods increase that to 45 × 24.3 ft and drop the centre to 212 fc. Those figures are for the bare bank. Meter again after adding a diffusion frame or spreading the columns.
Output and photometrics
Centre-beam output in foot-candles for 12 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.

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
The original Type 5751 sheet describes paired-lamp switching and an MC257G connector on each bank. Mole-Richardson lists the Type 5751-61REV with twelve independent switches and two Socapex pigtails. Identify the version from the head and its connectors before ordering cable or specifying individual lamp control.
Optics and mounting
The optional Type 5759 frame takes 6 × 6 ft diffusion on four Type 57869 extension arms. The head uses a removable 1⅛ in. yoke pin. The 92½ lb figure covers the lamped head. Account for the frame and arms separately when specifying support.
Comparable fixture
The Nine-Light Molefay takes smaller 650 W PAR36 lamps. Its spares, beam data and diffusion hardware belong to a different system. Nine-Light Molefay (Type 5541).
Field coverage and further reading
B&H’s archived Type 5751 listing identifies the original MC257G feed and removable yoke pin. Those details help distinguish it from the Socapex revision. B&H Type 5751 listing.
Rental and used-fixture checks
Ask for a photograph of the rear panel and a list of the twelve installed lamp codes. A package described only as a “12-light” leaves both the feeder arrangement and beam spread open. If the 6 × 6 frame is part of the order, confirm that all four extension arms travel with it.
