Overview
The Type 3391 is a 95-inch, three-circuit strip with nine reflectors. Each feed serves three cells, so a three-colour gel sequence can repeat three times across the head.

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 |
| FCL / FCZ | 500 W | 120 V | 3,000 K | 4.2 A |
| EHM / EHZ | 300 W | 120 V | 2,950 K | 2.5 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 95-inch body places 9 cells along a straight line. Each factory circuit can carry its own gel colour and dimmer cue.
- With 9 × 300 W EHM lamps, the connected load is 2,700 W. Gel choice and distance from the backing determine how much light reaches the wall.
Practical uses
When one gel colour reads unevenly across the backing, bring up its circuit alone. The three repeats make it easier to distinguish a dark lamp from a gap between heads.
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 3391. 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 3391 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
The six-light Type 3361 is shorter and comes in a three-circuit build compatible with the same colour sequence. Compare model lengths and circuits.
Field coverage and further reading
Mole’s rental catalogue lists the Type 3391 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
The bare head weighs 19½ lb. Mole lists three three-cell frame holders for a full set. Count the nine individual filter frames separately.
