Hoya 82mm HPS Grow Light Filter Kit

This 82mm HPS Grow Light Filter Kit from Hoya can be used to enhance images or video of plants while recording under grow lights with high-pressure sodium bulbs. The included filter is designed to reduce the yellow and orange cast of those light sources by selectively blocking light waves at 570 to 590 nanometers. This effect can be obtained when this filter is used on a film camera system with daylight film installed or on a digital camera system with its daylight white balance setting selected.
