The Smith-victor smartphone mounting kit is the perfect accessory for both the SV-RLED42 13.5” and SV-RLED 19” Ring Lights. The accessory foot slides easily into the shoe on the Ring Light and tightens down to securely stay in place. The adjustable tension grip will firmly hold smartphones 50mm to 100mm wide. When the smartphone adapter is removed, the accessory foot can be used to mount a light weight camera. By loosening the thumbscrew, the ball head can be adjusted for use both horizontally as well as vertically.
