Overview
The One-Light Molepar puts a single PAR64 lamp in a short housing with a ⅝ in. stand receiver. The lamp sets the beam spread. Rotating the housing turns the oval on its axis, while an optional front intensifier concentrates the beam. At 15 ft, Mole-Richardson lists 560 fc for the bare FFN very narrow spot and 900 fc with the Type 2275 specular intensifier.

Strengths and limitations
- The optional intensifier can increase centre output without changing the lamp. On the 15 ft chart, the medium flood goes from 150 fc bare to 225 fc with the diffuse intensifier.
- The PAR lens fixes the basic spread. Rotating the head reorients the oval. A change from a spot to a flood requires a different globe.
Practical uses
For a narrow shaft of light through a window, set the long axis of the oval first. At 15 ft the FFN pattern measures 6.4 × 3.7 ft bare and 4.4 × 3.0 ft with the 2275. If the window is the same width as the bare beam, fitting the intensifier may cut off the edges even though the centre gets brighter.
Output and photometrics
Mole-Richardson’s performance heading says 650 W, while its globe table rates the same six lamp codes at 1,000 W. The test wattage is unresolved. The figures below reproduce the published values by lamp code and intensifier. Use a meter to confirm the level from the lamp in hand.

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 manufacturer specifies a 25 ft lead with an inline switch and lists the plug as an ordering choice. The head accepts lamp versions for different supply voltages. Check the voltage on the actual globe before connecting the head.
Optics and mounting
Mole recommends the Type 2275 specular intensifier for the very narrow and narrow spots, and the Type 2276 diffuse intensifier for the medium and wide floods. The head also accepts 10⅛ in. scrims, the Type 41252A four-leaf barndoor and the Type 22761 Parsnoot.
Comparable fixture
For a larger area, the Six-Light Molepar (Type 5761) takes six 1 kW PAR64 lamps in pivoting pairs. Use the six-light chart for that configuration.
Field coverage and further reading
Renovo Rentals identifies its single PAR as Type 2271 and gives the 15 ft figure for an FFN lamp with the 2275. Ask for that accessory by number if the shot depends on its tighter beam. Renovo Rentals Type 2271 listing.
Rental and used-fixture checks
Check the lamp code, front safety screen and accessory clips. An order for a PAR64 head alone leaves the lamp spread and the intensifier unspecified. Confirm the intensifier type and the power plug with the supplier.
