For those of you who desire to use bottom or top lighting with a 100mm Light Ring or to replace your cell, follow these examples for ring disassembly.
NOTICE: This procedure only works with the new generation of 36 LED Light Rings purchased after December 12, 2015.
Step 1: Position the gray wire so it faces you. Place a piece of tissue over top of the Ferrocell to avoid fingerprints on the glass. Grip the outside bottom edge of the top ring with your index fingers, while pressing down on the edge of the cell with your thumbs. Step 2: Once the top ring is loose, gently push it away from the bottom ring.
Step 3: Gently slide the top ring over the gray wire and away from the bottom ring just far enough to remove the Ferrocell. Reverse the procedure to reassemble without a cell inside, or to install a replacement cell.
Thread the black strain relief (end of gray wire) into the top ring hole and squeeze the top and bottoms together. Plug it into power and place the Ferrocell on top of the ring assembly for a different view.
