The DL-DV320C LED Light with Variable Color Temperature from Dot Line Corp is a large, bright light that's compact enough for on-camera use but bright enough to warrant a spot on a light stand. Composed of 320 LEDs, the DL-DV320C is equivalent to a 200W incandescent light.
What's more, the light features adjustable color temperature that ranges from 2800K to 6500K, so you can match just about any ambient lighting. You can also step down the light output from full to 3/4, 1/2, and 1/4 strength.
The light can be mounted to a camera directly via the included shoe mount, which features a 1/4"-20 tripod socket at its bottom. There's also a shoe at the top of the light for mounting an identical unit (sold separately), for double the LEDs. The DV320C light includes a Sony NP-F750-style Lithium-ion battery and a charger, or you can plug the light into a wall socket using the included AC adapter.
