The FL-20G concentrates a Nanlite Bowens-mount spotlight into a variable 10° to 45° beam. Twist the barrel to set the spread, then use the included metal barn doors to trim spill. It suits a hard backlight or a pool on a background when the standard reflector lights too much of the room.

Nanlite names the Forza 300 and 500 II models, FC-300B and FC-500B, and the larger FS-series Bowens heads. The Forza 720B has separate operating guidance. For the compact FM-mount Forza 60 series, Nanlite lists the FL-11.

Setting focus and cut
| Adjustment | What changes |
|---|---|
| Spot towards 10° | The central pool gets narrower and brighter. Set the focus on the target before trimming the doors. |
| Flood towards 45° | Use more of the wall or background. Check the edges for spill when broadening a backlight. |
| Barn doors | Rotate and feather the leaves to cut a lens or wall. A separate flag farther from the head gives you more control when the leaf edge is too soft. |
On set
For a slash across a background, set the head far enough back to cover the full length, then trim height with opposing leaves. If the brief calls for sharply drawn edges or a window pattern, use the PJ-BM projector and shutters instead.
Rental and used-gear checks
- Confirm FL-20G on the pull sheet. The smaller FL-11 uses Nanlite’s FM mount.
- Check the glass, focus travel and door retention. Look for a bent leaf that drifts when the light tilts.
- For a 720B booking, give the crew the model-specific operating note and confirm the planned output and run time.
