The LitePanels CTB Gel Set for MiniPlus is a set of gels commonly used with tungsten (3200°K) MiniPlus fixtures--there are 4 blue color correction gels that will change the color temperature of the fixture, ranging from the full CTB (changes the temperature from 3200°K to 5600°K; from tungsten to daylight), 1/2 CTB (changes the temperature from 3200°K to 3800°K), 1/4 CTB (from 3200°K to 3600°K) and 1/8 CTB (3200°K to 3400°K). You also get 2 diffusion gels: Opal Frost, a light diffusion gel that cuts output by 1/2 f-stop, and Half White Diffusion, a medium diffusion gel that cuts output by 3/4 f-stop.

CTB gels can partially or fully balance a tungsten fixture to daylight; diffusion gels smooth and soften the light
