Overview
The 10 kW Skypan uses one tungsten globe in a 52-inch white reflector. With the diffuser holder in place, a 120 V DTY gives 420 fc at centre at 15 ft. Mole lists a 46.2 ft field diameter at that throw.
Key specifications

Replacement lamps
| Lamp code | Power | Lamp voltage | Nominal colour |

See the DTY lamp in the lamp lookup.
Mole lists both globe codes for this head. Its published light readings use DTY. Rated life varies by lamp make and version.
Strengths and limitations
The 52-inch reflector covers a wide backing from a short throw. At 73 lb with its holder fitted, the head and its mounting hardware need to be accounted for together.
Practical uses
For a cyc seen through stage windows, check the level on the backing at the outermost window as well as on axis. A 30.8 ft published field at a 10 ft throw gives a starting point for positioning adjacent heads.
Output and photometrics
All readings are for DTY at 120 V with the diffuser holder installed. The sheet gives no separate test for CP83 or for diffusion fabric. Field diameter marks the points at approximately half the centre intensity.
| Throw | Centre (fc) | Field diameter |
|---|---|---|
| 5 ft | 3,780 | 15.4 ft |
| 10 ft | 945 | 30.8 ft |
| 15 ft | 420 | 46.2 ft |
| 20 ft | 236.3 | 61.6 ft |
| 25 ft | 151.2 | 77 ft |
| 30 ft | 105 | 92.1 ft |
| 35 ft | 77.1 | 107.5 ft |
| 40 ft | 59.1 | 122.9 ft |
| 45 ft | 46.7 | 138.2 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
Mole rates the head for 120/240 V, up to 10 kW. A 10 kW DTY at 120 V draws approximately 83.3 A. The 3 ft head lead uses the MC258G Bates connector. Match the marked lamp voltage and the installed supply connection.
Optics and mounting
The 24637 holder and screen accept the 34724 four-foot-square diffuser frame. The catalogue also lists a 19210 socket adapter for a 5 kW lamp and a Type 42596 trapeze. The 10 kW chart applies to the original DTY setup.
Comparable fixtures
The 20 kW Skypan uses the same nominal reflector diameter. At 20 ft the 10 kW chart gives 236.3 fc at centre and the 20 kW chart gives 562.5 fc, each with its holder.
The 5 kW Type 245 has a smaller, 27½-inch reflector and published readings both with and without the holder.
Field coverage
Mole’s rental list identifies the 10 kW by Type 2461 and lists the lamp, holder, frame, scrims, screen and cable as package components. Mole-Richardson rental catalogue.
Rental and used-fixture checks
Confirm the installed lamp code and voltage with the rental house. A 5 kW socket adapter changes which globe is in the head and which output figures apply.
