The 13.4 x 12.7 x 3" 896S Bi-Color LED Panel from GVM is a compact light source with a wide color range from a warm 2300K to a cool 6800K, to meet any ambient light challenge, match other fixtures, or just for creative expression. The light's high CRI/TLCI rating of 97 is an indicator of accuracy in rendering color. The 896S has a tight 25-degree medium beam spread that can be further controlled with the light's 4-way barndoors. Simply swing one or more of the barndoor's leaves into the path of the beam to light areas that you want to and keep light from areas that you don't want illuminated. The light is dimmable too, from 10 to 100%. The 896S also features a Master/Slave Control Mode. Set one GVM LED light as the "master" light and other optional GVM lights as "slaves." The panel has a total of 12 channels that can each support up to 10 lights. Brightness and color temperature adjustments on the master light will be mimicked on the slave lights. The 896S runs on 110-220 VAC voltage using the included AC adapter, but it will also run on optional NP-F-type batteries when mains power is unavailable. The light comes with a diffusion filter and a bracket diffusion filter to soften the bright LEDs, as well as a case for storage and transport.
