At one time the only way you could focus your light source was by using a Fresnel or PAR fixture. Litepanels, a pioneer in the LED field, has changed that with the introduction of the Astra Bi-Focus Daylight LED Panel. Fresnels and PARs can be cumbersome but Litepanels uses two sets of lenses in the panel to allow spot-to-flood beam adjustment from 15degrees to 45degrees in a fixture that is only 5.3" thick. The 15-degree beam angle is handy in situations where you want to isolate a subject, control spill, or for long throw applications; whereas 45 degrees is ideal for wide coverage. And best of all you can adjust your coverage without moving the light, a valuable capability when the Astra is hung overhead or mounted in a hard to reach place. This is where the Astra's control features will be appreciated. While you can make adjustments on the unit, you can also control dimming (from 0 to 100%), focus, and turning the cooling fan on or off, with the purchase of a Bluetooth or DMX module - a great option in sound sensitive environments. The Astra Bi-Focus offers all the benefits of using an LED light source and then some. The light features a low power draw of 105W with a high output, while maintaining a high TLCI/CRI rating of 95, indicating accurate and precise color rendering. The Astra Bi-Focus Daylight is ready for worldwide use thanks to the included 100 - 240 VAC power supply, but it can also run on 14.4V professional batteries with the purchase of a V-mount or Gold-mount battery plate for situations where mains power is unavailable. Mounting options include a 5/8" receiver, or alternatively, two 1/4"-20 mounting points.
