The Stella 1000 LED Light from Light & Motion is a daylight-balanced LED source that packs enough features to cause many users to call it their ideal on-camera source. For location work, the Stella 1000 is hard to beat. With a very small form factor and weight of only 0.6 lb, it's barely noticeable in your kit case. What is noticeable is the clean, accurate color rendering output from the unit's flicker-free COB LED that gives it a rating of 90 CRI and 90 TLCI.
The Stella 1000 has a wide 120 degree beam that can be narrowed with the included 25-degree optical Fresnel lens or softened with the diffuser. The fan-less design is dead quiet for sound-sensitive locations and is dimmable either continuously or in steps. And, the housing is durably built. Not only can it survive repeated dropping on concrete from a height of 3.3', but it's also waterproof to depths of 328 feet!
The unit is powered by a built-in battery that charges in 1.0 hr. to 80% and 1.75 hr. to full charge, giving you a run time of 90 to 700 minutes depending on the power selected. You can also run the light from a D-Tap external battery source for longer shoots. Additionally, you can use mains power anywhere in the world thanks to the inclusion of a multi-voltage AC power supply. The Stella 1000 also comes with an external AC power supply and a 1/4"-20 adapter.
