A grid narrows the beam that is emitted from your light, cutting off unwanted angles and affording you a degree of precision that is unattainable without one. When rim-lighting your subjects, a grid is particularly useful for preventing unwanted flare into your lens.
This grid is fabric and foldable, keeping in step with the portability of the TL30. You'll hardly notice it in your bag.
This grid was made for the Godox TL60 only. It will not fit on other lights.
Note: Light not included.
