The Light Storm LS-mini20c Bi-Color LED Light from Aputure is a Chip on Board (COB) designed fixture with a 3200-6500K color temperature,
that consumes 30W of power while outputting 390 fc in spot mode and 67 fc in wide mode at a distance of 3.28'.
In addition to power efficiency this fixture also features accurate color rendering, with a CRI and a TLCI rating of 96.
The LS-mini20c can be seen but not heard, which is ideal for sound sensitive environments. The intelligent cooling system employs a temperature sensitive fan to regulate the heat.
There's 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-mini20c's performance is backed up by its design. The light goes through over a hundred fabrication steps.
The LS-mini20c is ready for worldwide use thanks to its 110-240 VAC power supply.
You can also use an optional V-mount or Gold mount battery plate and battery for external DC power when mains power is unavailable.
