Overview
The Two-Light Molefay places two 650 W PAR36 lamps side by side on a baby stand. The modules pivot independently. At 10 ft with two daylight FAY spots, opening the beam changes its width from 4.4 to 8.9 ft and drops the centre from 680 to 380 fc.

Strengths and limitations
- Two switches let the operator drop one lamp while the other stays at full voltage. The remaining globe keeps its rated colour.
- Switching one side off also moves the bright part of the field. Meter both marks when the head is covering two people.
Practical uses
For two seats seen through a side window, spread the modules until the two pools meet. At 15 ft the two FCX medium floods cover 18.0 × 7.4 ft at maximum width or 9.9 × 7.3 ft at minimum width.
Output and photometrics
Centre-beam output in foot-candles with 650 W, 120 V lamps. All lamps are on. Maximum and minimum refer to the width of the field as the modules pivot. In the original chart, the field boundary is where the intensity falls to roughly 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
Mole’s product page calls the 25 ft cord attached. Its original data sheet specifies a detachable Type 5727 lead with a twist-lock at the head. Check the inlet on the rental unit and order the matching cable.
Optics and mounting
Type 5728 shields and holder, Type 5724 diffuser frame. Each lamp has its own Type 55416 retainer. The yoke mounts on a ⅝ in. baby spud.
Comparable fixture
The Nine-Light offers a larger bank when a two-lamp throw cannot cover the required area. Nine-Light Molefay (Type 5541).
Field coverage and further reading
Mole illustrates the 5721 on its Type 2541 compact baby stand. The published performance chart is for both lamps on and gives separate readings for the two extreme module positions. Mole-Richardson rental catalogue, two-light package.
Rental and used-fixture checks
Check that both module pivots hold their aim, both switches operate and the correct lead and individual lamp retainers are present.
