The 19.7 x 13.6 x 3.7" WS 840D Daylight Widescreen LED Panel from Astora is a compact fixture with a 50-degree beam spread and a 16:9 format that gives it a wrap-around quality of light. Color temperature is a constant, flicker-free 5600K that makes the light a good choice for shooting outdoors or in spaces with large windows or for matching other daylight fixtures. The WS 840D has CRI/TLCI ratings as high as 97 and 98 - an indicator of precise rendition of color. Light intensity is variable from 0 to 100% and while you can make adjustments locally on the fixture, you can also do it wirelessly from a distance via the included remote control.
The 840D runs quiet thanks to its heatsink and efficient air flow - a valuable asset in sound-sensitive environments. The 840D is ready for worldwide use with separate purchase of a multi-voltage AC adapter but its dual NP-F plate allows it to run on optional batteries when mains power is unavailable.
