Grow Light HPS Filter 82mm Kit
- The Grow Light HPS filter was engineered for photographers, cinematographers, and social media managers that need to take pictures or video inside "Grow Houses" that use High Pressure Sodium Vapor (HPS) lights to simulate daylight during the plant growing process.
- HPS lights emit a very strong and very bright color spike in the 570-590nm (yellow/orange) area of the color spectrum.
- The Grow Light HPS filter specifically targets the color spike and blocks it from entering the camera. This allows the camera, phone, or video camera to Auto or Custom white-balance the scene with ease.
HPS lights emit a very strong and very bright color spike in the 570-590nm (yellow/orange) area of the color spectrum. This is great for growing plants, but horrible for taking pictures. The color is so strong that cameras can't properly color correct it in-camera even using custom white-balance options. We tested many different color-correction options, both in-camera and Raw processing, with varying levels of success without using a filter. Adding the filter, no matter how we chose to WB the room, always produced the best results because the Grow Light HPS filter specifically targets the color spike and blocks it from entering the camera. This allows the camera, phone, or video camera to Auto or Custom white-balance the scene with ease.
Check out the Before and After examples or the Video Tutorial below.
The 82mm Grow Light HPS filter is packaged in a kit that includes 3 step-up adapter rings that will allow you to attach the filter to a corresponding lens filter thread. Check out the video about the filter here. We go over how the filter works and how step-up rings works if you are not familiar with them.
Included in the kit:
- 82mm Grow Light HPS Filter
- 67-82mm Step-up Ring
- 72-82mm Step-up Ring
- 77-82mm Step-up Ring
If you need a smaller filter, we also make a kit using a 62mm filter. Click Here for the 62mm or if we do not include the step-up ring size you need, they are available online and at most local camera shops. Just make sure you ask for a step-up ring with the first number being the "lens" filter-ring size and the second number being the size of the filter.
NOTE: The images and video are straight from the cameras and phones we used to shoot them. No edits were made except for cropping. The "after" shots were only adjusted for exposure in-camera by increasing the ISO 2 full EV steps to compensate for the 2-stop filter factor.
