The fixture is powered by an array of seven potent 40-Watt 4-in-1 RGBL color mixing LEDs, each of which can be controlled independently. Through mixing the intensity of the primary LED colors, a huge gamut of output colors can be created to suit any mood or desired look. The fixture features a convenient Virtual CMY mode, which allows control alongside native CMY color mixing fixtures using hardware/software CMY color picker/pallete tools. It also offers Virtual Foreground and Background Color Wheel control as well as white light output with variable color temperature of between 2700K to 10,000K. This can be accessed either via linear control or a collection of 10 convenient presets. Meanwhile, through controlling the seven LEDs independently, the fixture can be used to generate impressive pixel-mapped effects. All of the LEDs used to construct the Focus Flex L7 are color calibrated to ensure uniform output of fixtures from different batches.

Motorized zoom allows the field angle of the Focus Flex L7 to be altered remotely between a wide 55-degrees and narrow 6-degrees, which allows it to be used for creating both broad washes and concise beams. Its extremely quick motor movement allows for the creation of stunning high-impact aerial effects, while 16-bit fine motor control ensures precise positioning.

A flexible fixture, the Focus Flex L7 offers seven DMX mode options (requiring between 16 and 50 control channels), appropriate to different applications, as well as a variety of customizable options, including selectable LED refresh rate and dimming modes. These are accessed through a color LCD display panel with 6-button menu interface located on the side panel of the fixture alongside a USB port which can be utilized for easy updates of future firmware releases.
