This flashtube is UV-Coated, or UV-Corrected. UV flashtubes have a yellow appearance, and they counteract the excess blue 5700° or higher output of non-UV coated flashtubes. UV Coating lowers the color temperature to 5500°, which is the color of noon daylight on a clear day.
The 3/8" Finger Nuts are used to securely lock the 9.Solutions 3/8" rods to different accessories. The 3/8" Connecting Nut is used to connect multiple 9.Solutions 3/8" rods together, allowing you to make longer rods.
Multiple rods can be used to create larger structures for rigging small cameras, lights, and a variety of other equipment.
