The Rainbow 2 Linear RGB LED Tube Light from Quasar Science is a 2' linear LED tube that offers multi-pixel control with high CRI/TLCI ratings, an SSI daylight rating of 74, and a tungsten rating of 91. The high-efficiency LEDs blend colors and brightness for millions of available colors and intensities. The integrated Pixel software provides control over 20 pre-built effects and macros, including rainbow, short circuit, customizable emergency lights, and much more. Each pixel can be controlled independently, or even grouped together so the light operates as a single pixel.

The Rainbow 2 is a useful linear LED for motion picture and content creation. A workhorse for everything from lighting actors to environments, it outputs up to 40.7 lux at 9.8' (5600K) and provides high-quality tunable white light and a high RGB color saturation. Multiple pixels maintain super smooth, flicker-free dimming and billions of available colors. This linear LED light offers incredible data connectivity whether wired or wireless, and can be powered anywhere via multi-voltage AC and DC power inputs. The integrated Ossium Mounting System (OMS) allows for rigging in ways previously unobtainable.

The perceptually distributed color palette created by advanced color science research offers artists instinctual lighting control. In addition, Spectral Control, a new technical and creative tool, provides artists with complete control over any color's spectral fingerprint.

The RGBX Spectral Science Color Engine produces spectrally based color calibration for more than one billion available colors.

Rainbow 2 white light conforms to illumination standards used by camera sensors. From 1750 to 10,000K, Quasar Science calibrates all CCT spectrums to their TM-30 reference illuminants, producing white light with high color rendition (SSI up to 91, TM-30 up to 94, CRI up to 95) to ensure the best photographic quality. CCT control provides an equal amount of color change throughout the entire Kelvin range.

Designed specifically for Quasar Science, the Ossium Mounting System pushes the boundaries of light placement while integrating seamlessly with industry standards for safer and faster rigging, with greater precision. A slender, secure rail along the length of the rear of the LED light provides multiple mounting points to accommodate any specific rigging need.

The Rainbow 2 can be controlled locally using the integrated controls and OLED screen for precise, repeatable results. The Cat 5/6 RJ45 in/out ports allow lead/follow control for multiple fixtures in an ad-hoc wired network. Wireless control is available using Bluetooth, DMX, Lumen Radio CRMX Wireless+ Bluetooth, and Artnet using Wi-Fi connectivity. In addition, Ethernet passthrough enables daisy chaining, simplifying network design, expansion, and flexibility.

Compatibility with a wide range of industry-standard batteries that can be mounted on separately available Ossium battery plates makes swapping batteries seamless. The external battery prevents the need for duplicate lights waiting on stand-by and eliminates associated shipping restrictions. The light is compatible with batteries from 12-30 VDC, using a 4-pin push-pull to PTAP connector.

Q: 1. Hello,I am concerned about how a person determines if a subject is in focus or not. Will my focusing green dot on my Nikon D610 work with this lens? Do I have to look at the image and determine focus by the picture quality. I have tried magnifying eyepieces and my eyesight will not allow me to use them.Thanks in advance.Bill

A: When the lens is stopped down the dot indicating that focus is achieved works fine. When working at a shallow depth of field, live view or a zacuto z pro finder helps with focus. If using live view a helpful hint I found on the internet is to program the center button of the multiselector (option f2 in the custom settings on a D-810 so that live view will immediately go to zoom mode when this button is pushed when you're in live view. This button can also be programed to zoom during playback to quickly check focus. You can program it for 50%, 100%, or200% magnification and it zooms centered on the site of your focus point. On a sunny day a hoodman is very useful. It's much smaller than a zacuto and can be quickly placed over the review screen to check exposure or focus in the sun when you can't see the liveview screen well. If relieing on the in camera focus dot for focusing with a narrow depth of field, there is quite a distance that the lens focus ring can be moved and yet still indicate that the camera thinks you are in focus. I did some test shots and I found that sometimes even though I thought I turned the focus ring until it was about in the center of where focus was indicated when coming into and out of focus as the ring was turned, the picture sometimes was still slightly out of focus. I found that if I started focusing in front of my desired site and turned the focus ring until the camera just indicated in focus I often achieved good focus, but when I began focusing behind the subject and turned the focus ring until the camera indicated in focus then the image was always fuzzy. This also happens with my other camera, a D700.
