The SDMV Grid for Speedbox 100-140 is a professional lighting accessory designed to control and direct light distribution in studio photography applications. This grid attachment helps prevent unnecessarily wide light spread, making it particularly suitable for high-contrast photography where precise lighting control is essential. With its 43-degree beam angle, the grid enables photographers to achieve targeted illumination and refined lighting results.

The grid features a cellular construction with individual cell dimensions of 5 x 5 x 4 cm, arranged in a four-sided rectangular pattern that provides consistent light control across the entire softbox surface. Mounting is accomplished through a secure hook-and-loop fastening system that ensures stable attachment to compatible Speedbox 100-140 softboxes. Constructed from durable materials, this grid maintains its structural integrity during regular studio use.

The rectangular form factor matches the dimensions of standard Speedbox 100-140 softboxes, providing full coverage without light leakage. This accessory is particularly valuable for portrait photography, product shots, and any application requiring controlled lighting with defined edges and reduced spill. The grid helps create dramatic lighting effects by concentrating light in specific areas while minimizing unwanted illumination of background elements.

Professional photographers will appreciate the precision this grid brings to their lighting setups, allowing for creative control over shadow definition and highlight placement. The product is manufactured by SMDV, a recognized brand in professional photography equipment. Compatibility is specifically designed for Speedbox 100-140 softbox models, ensuring proper fit and optimal performance. This lighting grid represents a practical solution for photographers seeking to enhance their lighting toolkit with accessories that provide measurable improvements in light control and creative possibilities.
