The Nanlite PJ-BM gives a Bowens-mount head a focusable projection lens and internal shutters. A gobo can put a window pattern on a wall, while the shutters can make a clean rectangular cut without a gobo. The 19° and 36° kits share a housing and take interchangeable lenses.

These Forza, FC and FS heads appear in Nanlite’s PJ-BM specifications. The Forza 720B is named explicitly. The FC-1200B and FC-1200C have a separate modifier chart in which Nanlite marks these projectors as unsuitable. The compact FM-mount PJ-FMM is a different system.

Lens, shutters or iris?
| Choice | On-set consequence |
|---|---|
| 19° lens | A tighter pool at the same throw. Useful for isolating an actor or projecting a small pattern from across a set. |
| 36° lens | Fills more of the wall when the room limits how far you can back up. Confirm the pattern size from the actual rigging position. |
| Internal shutters | Trim the top, bottom and sides independently for a doorway, a strip or a rectangular window. |
| Adjustable iris | Makes a smaller round pool from the same lens position. Include it when the size of the circle needs to change between takes. |
On set
For a foliage breakup, focus on the wall, then soften the image slightly if the leaves look pasted on. If only one side needs to fall off, use a shutter for that edge so the focus stays consistent across the rest of the pattern.
Rental and used-gear checks
- Confirm the case label specifies PJ-BM-19 or PJ-BM-36 and open it to check the actual lens.
- Include the gobo holder and correct gobo size. Inspect the glass and check that the shutters move freely.
- Account for the head, housing and lens in the stand choice. Use the projector’s support yoke as directed and check the complete assembly at working tilt.
