For photographers and videographers, lighting often means compromise. Fixed-beam LED panels are versatile but lack precision. Spotlights are powerful but inflexible. A focusable LED video light solves this by combining both in a single compact fixture.
The GVM PF100B is a 100W bi-color COB LED focusing light designed for creators who need versatility without the bulk. With a built-in optical Fresnel lens that adjusts from 15° spot to 45° flood, this single light replaces a bag full of modifiers.

Focusable Beam: From 15° Spot to 45° Flood
The PF100B features a built-in optical Fresnel lens that adjusts smoothly from a narrow 15° spot to a wide 45° flood with a simple twist of the focus knob.
| Beam Setting | Effect | Best For |
| Spot (15°) | Concentrated, punchy beam with strong directionality | Dramatic accents, product highlights, rim lights, long throws |
| Flood (45°) | Wide, even spread with soft falloff | Key lights, interviews, portraits, soft fill |
This versatility means one focusing LED light for photography handles multiple lighting tasks. Need to isolate a product with a tight beam? Twist to spot. Need soft, even illumination for an interview? Twist to flood. No extra modifiers required for most everyday shooting scenarios.
The PF100B delivers consistent and uniform illumination across the entire 15°-45° zoom range at any color temperature setting. Its advanced optical design provides a softer fall-off compared to conventional COB spotlights, reducing harsh shadows and eliminating hot spots.
Bi–Color Temperature: 2700K – 6800K
The PF100B covers everything from warm tungsten-style looks to cool daylight with its 2700K–6800K adjustable color range. With CRI and TLCI ratings of 97+, the PF100B delivers accurate color rendering and faithful skin tones straight out of camera — minimizing post-production color correction.
This focusable bi-color LED light gives you precise control over both beam angle and color temperature, making it adaptable to almost any shooting environment.
Silent Mode for Audio–Sensitive Shoots
The PF100B features an advanced active cooling system with multiple fan modes. The Silent Mode disables the cooling fan entirely for clean audio capture — essential for interviews, podcasts, and dialogue-heavy shoots.
Three fan modes are available:
- Smart— Adjusts automatically based on temperature
- High— Maximum cooling for extended shoots
- Silent— Fan stops for sound-sensitive environments (output reduced to 10-20W)
This makes the PF100B a reliable focusable video light for photography that won’t compromise your audio track.
Professional Control Options
The PF100B offers flexible control options:
Onboard control — Physical knobs and LCD screen on the fixture for direct adjustments
Bluetooth APP— Control via iOS/Android devices with Mesh networking support, Bluetooth range up to 50 meters
CCT Mode— Adjust both brightness and color temperature
Compact and Portable Design
At just 1.53 kg, the PF100B is genuinely portable. A portable focusable LED light means you don‘t need to pack multiple modifiers for different looks — one light, one knob, and you’re ready for whatever the location throws at you.
The fixture supports V–mount battery power (sold separately) for location shoots, and a built-in barn door is included for additional light control.
