Quasar Science Double Rainbow and Rainbow 2 RGBX LED Lights – Review – CineD

February 21, 2022 by No Comments

The tube LED light has been a popular form factor for filmmakers for a few years now due to the ease of transport and mounting, the ability to wrap light around a subject, and the simple modular design making it easy to add more tubes for more light. Lighting manufacturer Quasar Science, now a Vitec company, has updated their RGBX Rainbow series with a second generation called the Rainbow 2 and the Double Rainbow.

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!

I’ve been a fan of Quasar Science’s products for years now. Primarily I utilize their T-8 and Crossfade tubes, even adding Quasar tubes in a few Kino Housings. The daylight or tungsten T-8 tubes can be zip-tied or even taped to ceiling tiles to replace ugly overhead office lighting, and their small weight and low power draw make them easy to work with.

Though I’ve never had an opportunity to work with the original Rainbow Fixture, the updated versions – given the connection options on paper and the mounting system – are definitely appealing to me.

The Double Rainbow is available in a 2′ 50W and 4′ 100W version, and I had access to both sizes for this review. Currently, the pricing sits at $900 for the 2′ and $1,300 for the 4′. These prices place the Double Rainbow fixtures as a premium offering in the LED tube category.

One of the banner features for the Quasar Science Rainbow series is the addition of pixels, with the 4 ft. Double Rainbow containing 48 pixels and the 4 ft. Rainbow 2 containing 24 individually controllable pixels. This is more pixels than the new PavoTube II from Nanlite (which we also reviewed!) or the Astera Titan. As used here, “pixels” are small LED diodes or clusters of diodes that can be controlled independently or programmed as a group. I like using programmable pixels for light engine zone control in process car filming or specific VFX gags

I’ll admit I was skeptical that the overall LED tube exterior design we’ve all become used to needed much tweaking. This is because T-12 or 1.5-inch diameter-sized tubes have become a standard size based on the older fluorescent tubes. Also, there is an entire 3rd party ecosystem of accessories available for T-12 tubes. Because of its non-standard size, the double Rainbow currently doesn’t have a ton of support from 3rd parties. Hopefully, that will change over time!

To me, the exterior look of the Double Rainbow (basically double the width of the Rainbow 2) is lovely, and, story permitting, I’d choose it over a T-12 tube, thereby avoiding the music-video-look cliché.

Taking a 2′ Double Rainbow out of the case, I was immediately impressed by the build quality and connectivity options. USB-C for firmware, Ethernet port for daisy-chaining, and wired or wireless DMX make this fixture very handy for professional shoots or in-studio or on-stage projects where grid access can be tricky. You can use ethernet to pass commands from fixture to fixture, but unfortunately, at this time, you can’t pass through power from fixture to fixture. Quasar …….
