Original Soft Egg crates® are made up of uniform parallel cells that control off axis light at right angles to the diffuser. A secondary effect is that original Soft Egg Crates® reduce the near to far light ratio, creating a more even lighting, which is ideal for when a subject is moving towards or away from the light. This more even lighting occurs due to increased occlusion† by the cells at closer distances.
Lighttools ez[POP] Soft Egg Crates combine all the light control benefits of Original Lighttools with faster set up and a built-in tensioning frame. The built-in tensioning frame keeps the Soft Egg Crate taut and in perfect formation regardless of how your softbox is angled .
CUfocus® Soft Egg Crates® are made up of specially angled cells to provide full-source illumination at close distances. These angled cells also tightly block light around the desired subject avoiding spill in the most confined spaces. Full-source illumination at close distances is not possible with original Soft Egg Crates due to occlusion†.
CUfocus Soft Egg Crates® are available to purchase or rent directly from Lighttools.

As the inventors of the Original and CUfocus® Soft Egg Crates®, we are the world leader in soft light control.
•A complete range of soft light control tools.
•Models to fit most manufacturers' lightbanks.
•Unparalleled quality assurance, dependability and 3-year warranty.
•Personal support with product selection, technical specifications and photometric data.
The off axis portion of the light is controlled by the cell size.
Cell size, measured in degrees, describes the maximum angle of the off-axis light. A 20° Soft Egg Crate® is our narrowest model, giving you the greatest ability to aggressively control light. At the same time this model creates the most significant occlusion† at close distances. The 60° is the widest cell size and, therefore, is the most modest light blocking tool.
The 30°/50° and the 20°/60° models offer two variations in a single Lighttools® Soft Egg Crate®. You can easily vary the amount of soft light spread in four directions by rotating these models of Original Soft Egg Crates®.
A specific Lighttools® cell size designation gives the same cutoff of light whether it is on a lightbank or an Overhead Frame. The only difference would be the square footage of light coverage determined by the light source size variation. The exposure changes for all our Soft Egg Crate models® can be calculated by applying the diagonal dimension to the Lighttools Occlusion Reference Charts.
Light loss on center axis is minimal at a distance greater than 3x the diagonal dimension of the light source. With Original Soft Egg Crate® models the light loss, at these distances, is less than a 1/4 f-stop, even on our most dramatic 20° model. At closer distances there is a much greater loss due to occlusion; of up to 2 f-stops.
With CUfocus† Soft Egg Crates® full-source illumination occurs at the focus point. This means no light loss occurs at that point on center axis.
Refer to the Lighttools Occlusion Reference Charts to view exposure changes with Soft Egg Crates for any diffuser size.
Lighttools Stretch Frames eliminate sag - to give you complete control - regardless of how much your lightbank is angled downward.
Essential for larger softboxes, Stretch Frames are a one-piece, collapsible frame that are constructed with the usual high standards of all Lighttools products. When inserted into the softbox, the Stretch Frame creates rigid sides to keep original Lighttools Soft Egg Crate taut for 100% efficiency.
One Stretch Frame can be used for all Lighttools Soft Egg Crates of the same outside dimensions, regardless of their cell size. This includes Original and CUfocus models.
