Light red 1A type safelight filter for the Kodak 2-Way Safelamp and other safelight housings that accept 3¼"x 4¾" filters. These permanently pigmented plastic filters can't shatter like glass filters can. Light red 1A type filters are suitable for use with many B&W photographic papers but are also commonly used for orthochromatic graphic arts materials. Please refer to the product data sheet packed with the material you are using to confirm that this is the recommended safelight filter for that specific material.
NOTE: No safelight filter is 100% safe for an indefinite period! Always perform a safelight test with the materials you're using to determine the maximum exposure before fogging begins to occur. For information on how to conduct safelight testing, click here.
