The YN-408 Bi-Color LED Ring Light with Phone Holder from Yongnuo features a uniquely shaped light with a color temperature that can be adjusted from 3200 to 5600 K, allowing it to match other lights, ambient lighting conditions, or simply to enhance creative expression. The YN-408 can be mounted on an optional handle or light stand, enabling you to shoot through it for a silky smooth, nearly shadowless effect that flatters your subject's complexion. Ideal for self-photographers, a smartphone holder is also included, while another bonus is the unique circular shape of the light that reflects in your subject's eyes. The YN-408 is powered by the included AC adapter but can also be used in locations without AC power with an optional NP-F lithium-ion battery.
