The VELVET Light 4Long-Studio Bi-Color LED Fixture offers directional lighting in a slim form factor through 192 individual LEDs evenly arranged between four articulated strips. Manually bend the strips into a concave or convex shape to adjust the beam angle between 30 and 75 degrees to find the ideal setting for each scene. The 4Long-Studio LED Fixture includes barndoors and a softbox diffuser to help shape your light, which can be dimmed in 1/2 stop increments and is flicker-free at up to 3000 frames per second.

The 4Long-Studio offers a notable color temperature range from 2500 to 6500K plus green/magenta correction from quarter plus to quarter minus green, allowing you to easily match other light sources and avoid complex post-processing. A CRI rating of 90 promises a high degree of tonal fidelity across the entire color range, while the LEDs are rated to last for approximately 50,000 hours. Adjustments can be made on-board via buttons on the back panel or with an optional DMX board thanks to 5-pin XLR in and out ports. Made of anodized aluminum with a passive cooling system, the 4Long-Studio runs on 90 to 264 VAC power provided via a 6.6' powerCON cable.
