Urban Effect Filters from Lee Filters allow users to create the look of sodium street lighting with either a tungsten or daylight source. The range includes 604 Full CT Eight Five, which converts daylight to tungsten with a red bias and creates an orange effect similar to sodium when used on tungsten. 642 Half Mustard Yellow is a half-strength sodium light effect, and 643 Quarter Mustard Yellow is a quarter-strength sodium light effect, both for use with daylight sources. For tungsten, 650 Industry Sodium blends with sodium lights; 651 HI Sodium creates a high-pressure sodium look; 652 Urban Sodium provides the orange glow associated with sodium light; and 653 LO Sodium, outputs a low pressure sodium look.
