Overview
The Type 5781 Moleeno is a 24 kW bank with six columns of four PAR64 lamps. Each column swivels. From 75 ft, a full set of FFR medium floods puts 330 fc at the centre of a field about 40 ft wide. With FFS wide floods in the same head, that field opens to nearly 70 ft and the centre falls to 105 fc.

Strengths and limitations
- Six pivoting columns let a crew spread the bank across a wide backing or concentrate the beams along one axis.
- The frame breaks into four sections and the yoke into two. Those features matter for access because the assembled head measures 69 in. across before the diffusion frame is fitted.
Practical uses
For light through a distant window, compare the centre reading and the width at the window plane. At 100 ft the FFP narrow spot chart gives 520 fc over 28 × 17.7 ft. The FFR medium flood gives 185 fc over 53.7 × 25 ft. Spreading the columns changes both figures.
Output and photometrics
Centre-beam output in foot-candles for 24 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
Each four-lamp column has two toggles. Mole-Richardson lists an attached 3 ft cable with an MC257G 60 A Bates connector on each bank. The head carries a 200 A maximum rating. Confirm the bank feeds and switching on the specific unit when ordering the distribution package.
Optics and mounting
The Type 57870 frame holds 6 × 8 ft diffusion and uses four Type 57869 arms. The lamped head weight excludes this frame and the stand. Mole-Richardson illustrates the assembly on a Type 500572 folding crank stand.
Comparable fixture
The Nine-Light Molefay has nine 650 W PAR36 positions. Its much smaller lamp face and different globes make it a separate option when a full-size Moleeno will not fit. Nine-Light Molefay (Type 5541).

Rent For Event identifies its 24,000 W Moleeno rental as Type 5781 and lists the sectional frame. Check the supplied support and accessories against the order. Rent For Event Type 5781 listing.
Rental and used-fixture checks
Ask whether the head travels assembled or in sections. Confirm the number and beam codes of the globes in the case, the stand, and the four extension arms if the shot calls for the 6 × 8 frame.
