The Smith-Victor 401704 17" Bi-Color LED Ring Light Features a CRI of 95 with step-less color temperature adjustments buttons for immediate tungsten, daylight and 4250K. The redesigned reflector provides softer and smoother light than previous models. Luminance can be adjusted from 1% up to 100%. The digital LCD screen allows easy set up of the desired color temperature and brightness. Additionally it comes with a remote that provides control over the settings. This new generation of Bi-Color Ring Light also has the option of using 2 Li-ION (NP-F) batteries so the ring light can be taken out of the studio to any location you need it.
