The LED1000B puts you in control. It has amazing power for its size. The included barn doors, softening diffusers, wireless remote control, and onboard touch control panel let you shape, feather, soften, and adjust light to your liking. The LED1000B includes generously long AC power cables; but, you can also power it by 2 or 4 NP-F type batteries (sold separately). The high CRI of 95+ means the quality of light from the LED1000B is clean, natural, and brilliant. This unit uses a bi-color design so you can also control the amount of warmth or coolness. ProMaster's special FULL POWER mode gives you the most light output when you need it.
