This Crossfade X Linear Bi-Color LED Light Tube from Quasar Science measures 4' long and is a low-profile linear light source that offers a simple, broad spectrum and tunable white light from a beautifully warm 2000K to a crisp 6000K. Whether for lighting actors or environments, its simplicity delivers versatility at an exceptional value. Use one as a key light, rig three for a 3-point lighting setup, install 10 as architectural lighting accents, or go big and stack 100 into a massive LED array with unprecedented energy efficiency for illuminating stage backings, or for rigging above diffusion for the perfect skylight.

The fixture's light weight makes it easily hand-portable and opens up rigging possibilities. Carry one or two fixtures with camera equipment on public transportation, and quickly tape them up to walls for temporary lighting setups without safety worries. The scalable design allows them to be stacked in columns and rows to create large LED panels and arrays of any size, or line them up end-to-end for long linear lighting sources. Construct geometric patterns and 3D structures for endless visual possibilities.
