Overview
The two-lamp Botticelli is an indirect tungsten softlight with separately switchable lamps. The 2 kW version takes two 118 mm lamps. A similar-looking version takes longer 189 mm lamps, so the model number matters when ordering spares. With the silver reflector, the published beam covers about 4.0 × 4.4 m at a 3 m throw.
Key specifications

Strengths and limitations
- Each lamp has its own switch. Dropping to one lamp reduces output while the operating filament stays at its rated voltage.
- The 118 mm and 189 mm versions look similar from the front. A lamp ordered from wattage alone can be the wrong length.
Practical uses
For a broad room fill, set the lamp count before balancing the foreground. At 3 m the silver-reflector chart gives 968 lux at centre. At 6 m it gives 242 lux. Meter the one-lamp setting separately if you switch a lamp off during a setup.
Output and photometrics
De Sisti’s two-lamp model sheet identifies P2/20 lamps at 230 V with silver reflectors. It gives one output chart. There is no separate measured one-lamp configuration in the sheet.
| Configuration | Distance | Lux | Foot-candles |
|---|---|---|---|
| P2/20 · 230 V · silver reflector | 3 m | 968 | 89.9 |
| P2/20 · 230 V · silver reflector | 6 m | 242 | 22.5 |
| P2/20 · 230 V · silver reflector | 9 m | 108 | 10 |
| P2/20 · 230 V · silver reflector | 12 m | 61 | 5.7 |

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
With two 1,000 W lamps installed, the 118 mm head can run one lamp or both. The separate 189 mm version has its own lamp table and higher maximum rating. Read the model plate before choosing replacement lamps.
Optics and mounting
The double front track accepts the colour frame and stackable eggcrates. De Sisti lists the 3116.100 at 24.5 mm deep and the 3116.200 at 49 mm. Select the deeper grid when more off-axis control is needed.

Rental and used-fixture checks
Read the model number at the head and confirm the lamp length. Test both switch positions, check that the reflector is seated and inspect the accessory latch. Record reflector finish before using the published figures.
