Our editorial take on the Quasar Science Double Rainbow Linear LED Light (2')
The Quasar Science Double Rainbow represents a significant step forward for linear LED lighting, moving far beyond a simple iterative update. This fixture is a thoughtfully engineered tool that directly addresses long-standing frustrations professional users have had with tube lights. With its impressive brightness and professional-grade construction, it immediately establishes itself as a serious contender for demanding on-set applications. It's clear that a great deal of user feedback went into its design, resulting in a product that feels both innovative and practical.
The key advancements are found in its core functionality and usability. The RGBX LED engine delivers exceptional color science, providing not only vibrant, saturated colors but also high-quality tuneable white light. This versatility is critical for modern productions. The most celebrated upgrade, however, is the vastly improved mounting system. It offers a level of security and flexibility that streamlines workflows and opens up new creative possibilities. Combined with versatile connectivity options for robust system integration, the Double Rainbow proves it is a top-tier instrument built for the rigors of professional filmmaking.

We’ve known about these fixtures for a while, but they are just now starting to ship widely. We got our hands on a few Rainbow 2s and Double Rainbows, and I am happy to share my thoughts with you!
These slim, fairly compact lights from Quasar Science offer detailed control, robust color science, high efficiency, and versatile connectivity—plus a pretty cool mounting system.
When I popped open the case with the new Rainbow 2 and Double Rainbow demo tube lights, I was instantly impressed with how far Quasar Science has come. These new lights have been thought out, and they addressed many issues with tube lights—namely, the mounting system.
This flagship bi-color LED delivers massive output for large-scale productions. Precision color control and professional-grade construction make it suitable for cinema and broadcast. The included flight kit supports transport and protection on location.

About this product
This Double Rainbow Linear LED Light from Quasar Science is a 2' RGBX light with versatile output options for creative results. It advances the design legacy of the Rainbow 2 tubular form factor by doubling the lamp width, but retains a low-profile shape so it can fit in all the same tight spaces. The expanded RGBX color profile allows seamless color matching, full gamut mixing, and a variety of available light effects.
