1. An LED lighting device configured for providing light suitable for a commercial image recording, the LED lighting device comprising:

  • a support structure;

    a housing for the support structure;

    an array of LED emitting devices mounted on the support structure, wherein the array of LED emitting devices is configured to emit five different colors of light and comprises;

    a first set of LED emitting elements configured to emit light of a first color;

    a second set of LED emitting elements configured to emit light of a second color;

    a third set of LED emitting elements configured to emit light of a third color;

    a fourth set of LED emitting elements configured to emit light of at a fourth color; and

    a fifth set of LED emitting elements configured to emit a broad-spectrum white light within a predetermined Kelvin temperature range; and

    a controller coupled to the array of LED emitting devices and configured to receive commands for operating select ones of the LED emitting devices with varying amounts of power to produce light consisting of varying amounts of the five different colors provided by the first, second, third, fourth, and fifth sets of LED emitting elements to produce many different colors outputted from the lighting device, and further comprising an LED driver, the LED driver configured to selectively provide electrical power to the array of LED emitting devices;

    wherein the housing has a linear form factor substantially that of a fluorescent tube having an axial direction and having a diameter of no greater than about 41 mm, and further comprising an electrical input connection for receiving input power, wherein the input connection is in electrical communication with the LED driver, andwherein the housing has opposite ends and the support structure is in a form of an elongated and narrow surface extending in the axial direction and the housing having a top side and a bottom side which each extend in the axial direction, and wherein the LEDs are configured to emit light from the top side of the housing along a length of the housing between the opposite ends, and the top side of the housing has a diffusion cover extending the axial length of the support between the ends.
