The 19.7 x 13.6 x 3.7" WS 840B Bi-Color 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. The WS 840B's flicker-free output is variable from 3200 to 5600K, allowing it to meet any ambient light challenge, match other fixtures, or facilitate creative expression, while its CRI/TLCI ratings as high as 97 and 98 indicate 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 840B runs quiet thanks to its heatsink and efficient air flow - a valuable asset in sound-sensitive environments. The 840B 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.
