Overview
An eight-light Type 2691 covers just over seven feet of a straight cyc run. Mole offered two- and four-circuit builds. The four-circuit version puts two 1 kW lamps on each feed at full load.

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 84½-inch body places 8 cells along a straight line. Each factory circuit can carry its own gel colour and dimmer cue.
- With 8 × 500 W FCL lamps, the connected load is 4,000 W. Gel choice and distance from the backing determine how much light reaches the wall.
Practical uses
Where two long strips meet, match the colour order across the joint. A pair of identical gels side by side at that point can leave a visible stripe when the other colours fade down.
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 2691. 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 2691 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. Manufacturer’s accessory drawings.
Comparable fixtures
The four-light Type 3341 fits half the number of cells into a shorter run and can give one circuit per lamp. Compare model lengths and circuits.
Field coverage and further reading
Mole’s colour-layout drawings show how the circuits continue through the corner of a cyc. The four-circuit example repeats two gel colours, with a separate feed for each group of cells. Molorama layout drawings.
Rental and used-fixture checks
Allow for an 84½-inch rigid body on the cart and at the stage door. The listed 16 lb covers the head. Four two-cell holders and eight filter frames add to the package.
