De Sisti Wyeth 2 kW

Last Updated 4 hours ago

Overview

Wyeth 2 kW pole-operated head

The Wyeth 2 kW places two independently switched tungsten lamps in a shallow reflector. It gives a broad fill from a low grid without needing a separate bounce. With the silver reflector, De Sisti measured 1,212 lux at 3 m across a field approximately 4.2 m wide by 3.9 m high.

Strengths and limitations

  • A second switched lamp adds level without adding another stand or moving the source. The shallow reflector is useful over a desk or beneath a low studio ceiling.
  • At 6 m the measured centre is 303 lux with the silver reflector. The broad spill can lift both the subject and the background, so distance and eggcrate choice matter.

Practical uses

Over a presenter desk, start with both lamps and establish the fill level at the far mark. To bring the level down, switch one lamp off and meter again, or move the unit. Check the shine on the desktop before locking the tilt.

Output and photometrics

De Sisti provides one chart for the two-lamp head with the 230 V P2/20 and silver reflectors. Only this documented configuration is available in the calculator.

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.

Power and controls

The two switches control the lamps separately. With both 1,000 W lamps operating, their combined nominal load is 2,000 W. A single switch gives the option to reduce the load without dimming the remaining filament.

Optics and mounting

The hinged socket compartment drops down for lamp access. The spring-loaded double track accepts front accessories, including stackable eggcrates. A white reflector and a silver option are documented. The published readings use silver.

Field coverage and further reading

B&H distinguishes the stand-mounted 3210.210 package from the pole-operated hanging model.

Rental and used-fixture checks

Test each lamp and switch separately. A head with one dead lamp can still look evenly lit from the front. Confirm the type and voltage of both globes, the reflector finish and whether the package includes the eggcrate.
