Light Storm LS C120D II Daylight LED Light from Aputure is a chip-on-board (COB) fixture with a 5500K color temperature. It consumes a negligible 180W of power while outputting 135,000 lux, equivalent to a 1000W hot light at a distance of 1.6' with an optional Fresnel. In addition to power efficiency, the fixture also features a high CRI/TLCI rating of 96/97, an indicator of precise rendering of color. Ideal for sound-sensitive environments, the LS C120D II is seen but not heard thanks to an intelligent cooling system that employs temperature-sensitive fan to regulate the heat. There is also an Auto/Force button that triggers maximum cooling. In any case, even at maximum power, the fan noise doesn't exceed 18 dB: basically the sound of a person breathing. The LS C120D II's performance is backed by its design. The all-aluminum construction goes through over a hundred fabrication steps. The reflector and accessory mount is the widely-used Bowens S-type, while the wired controller is separated from the fixture's body, making it lighter and reducing its size. You can make light intensity adjustments locally on the fixture or remotely with an included wireless remote that allows you to control dimming functions from as far away as 328'. Yet another way to turn the light on and off or dim it from 1-100% is via onboard DMX remotely from a console. The LS C120D II is ready for worldwide use thanks to its controller's 110-240 VAC power supply. You can also use its V-mount battery plate for external battery power when mains power is unavailable. The LS C120D II is delivered as a kit with a reflector, controller, and a dedicated carrying bag to protect the light during travel and storage. 25% Brighter than Predecessor The LS C120D II boasts a luminance of 135,000 lux at 1.6' away with the optional Aputure Fresnel.5500K Daylight Color TemperatureCRI/TLCI: 96/97Wired Controller Box
