When sourcing in bulk, verify the LED bead count (e.g., 240 or 480 beads) as this directly impacts brightness and light softness. Check the input voltage compatibility (110V-240V) to ensure the product can be sold globally without power adapter issues. For mobile-centric buyers, ensure the inclusion of USB charging ports (5V/2A) on the ring light body to keep smartphones powered during long broadcasts. Furthermore, confirm the tripod stability and maximum load capacity, especially if users will mount heavy DSLR cameras.
