Overview
The twelve-light Molorama spans 10 ft 6½ in. Its circuit configuration changes the dimmer requirement considerably. It carries six lamps per feed on the two-circuit head, four on the three-circuit, or three on the four-circuit.

Replacement lamps
| Lamp codes | Per lamp | Supply | Rated colour | Current per lamp |
|---|---|---|---|---|
| FCM / FHM | 1,000 W | 120 V | 3,200 K | 8.3 A |
| EME / EMF | 800 W | 240 V | 3,200 K | 3.3 A |
| EJG / EMD | 750 W | 120 V | 3,200 K | 6.3 A |
| FDF / FDN | 500 W | 120 V | 3,200 K | 4.2 A |

Mole specifies a T-3 lamp, 4 11/16 in. overall, operated horizontally within 4°. EME and EMF are the 240 V pair. For examples of these lamp codes in other heads, see FCM · EMD · FDN · FCZ.
Strengths and limitations
- The 126½-inch body places 12 cells along a straight line. Each factory circuit can carry its own gel colour and dimmer cue.
- With 12 × 1,000 W FCM lamps, the connected load is 12,000 W. Gel choice and distance from the backing determine how much light reaches the wall.
Practical uses
Plot the ends of the 126½-inch housing as well as its centre. A shorter head at the start of the return can follow the curve while the twelve-light stays parallel to the straight wall.
Output and colour
Mole’s strip specification lists the lamps and circuit loads. It gives no measured foot-candles at a stated wall height or setback for the Type 3121. For a multi-colour wash, meter each colour at the base, centre and top of the backing with the show gels in place.
Power and controls
The Type 3121 has no onboard switch. Mole specified 36-inch leads for each circuit and offered different plugs. Identify which cells each lead serves before patching the dimmers. The per-circuit ratings above are for 1,000 W lamps on 120 V.
Optics and mounting
Each filtered cell takes one Type 27240 Molequik frame. The front holders for this length are listed in the specification table. Mole lists the Type 26530 bracket pair for floor use and the 26120 end hangers for pipe mounting. Its removable front holder increases the fixture profile to 13⅛ in. high by 12¾ in. deep.

Comparable fixtures
Two six-light Type 3361 strips can follow two different wall angles. The twelve-light adds the option of a four-circuit layout. Compare model lengths and circuits.
Field coverage and further reading
Mole’s rental catalogue lists the Type 3121 by both model and lamp count. It also lists the frame and floor-bracket or hanger package. Mole-Richardson rental catalogue, Cycs.
Rental and used-fixture checks
Mole lists 26 lb for the head alone. A full complement of holders and twelve filter frames has to travel with it. Confirm the circuit version on the order and on arrival.
