The Broncolor B-33.107.00 P70 is a specialized light shaping accessory designed for use with Broncolor flash heads and continuous lights. It is a 70-degree wide-angle reflector that attaches to the front of a compatible light source to modify its beam spread and quality. The primary function of this reflector is to produce a broad, even field of light with soft, gradual fall-off at the edges, making it well-suited for lighting large areas, providing fill light, or creating a soft, wrappy key light in close quarters. Its 70-degree angle offers a balance between coverage and control, wider than a standard reflector but more focused than a true umbrella or softbox.

Constructed from high-quality, lightweight aluminum, the reflector features a highly reflective silver or white interior surface that efficiently directs the light forward while maintaining spectral integrity. The design often includes a recessed front to help control spill and maximize efficiency. It attaches via Broncolor's proprietary quick-lock mounting system (likely S-fit or similar), ensuring a secure and precise connection that aligns the reflector perfectly with the flash tube for optimal optical performance. The accessory is a fundamental tool in a photographer's lighting kit, valued for its simplicity, durability, and ability to deliver a clean, controllable light suitable for both studio and location work.

By using this reflector, photographers can achieve a more natural and flattering light quality compared to the bare flash tube, with reduced risk of hotspots and harder shadows. It is a versatile choice for portrait, fashion, and product photography where a soft yet directional light is desired without the setup time or bulk of a large softbox.
