Not only a tube light but a telescopically adjustable one, the T60 Telescopic RGB LED Video Light from Sirui is highly portable and easily suitable for a wide range of applications. It telescopically adjusts from 18 to 29" in length. A 1/4"-20 thread on the bottom lets you mount the light on an included mini tripod or various other supports. On the opposite end is a pull-out ring for hanging the light on a hook or something similar. You can also use the light handheld.
