The Onyx 120 Bi-Color On-Camera LED Light from ikan has an output of roughly 100W at full power, yet draws only 15W. It is a bi-color light that enables you to adjust the color temperature of the fixture's output from 3200 to 5600K and features a CRI of 95 and TLCI of 96 in both Tungsten and Daylight. Power on/off, dimming, and color temperature are controlled from the back of the fixture via four buttons. A two-digit LED screen is shared for dimming and color temp, with an indicator light informing you of which characteristic you are controlling.
The fixture powers from an L-series battery, and ships with the equivalent of a 550 L-series battery. You can also power the fixture from an optional AC power supply that outputs 13 to 17 VDC. The built-in diffusion helps prevent the effect of multiple cast shadows that afflict some LED array-type lights. A built-in 1/4"-20 threaded mounting hole, and the included cold shoe adapter enable mounting the fixture on your camera.
On the back of the fixture are four buttons:
M - select
The M button enables switching between dimming and color temperature. An LED indicator lights up to indicate which characteristic of the fixture you are controlling. A two digit display screen indicates dimming from 10 to 99% and color temperature from 32 to 56.
