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 | Meilleur pour |
| 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.
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:
- Smart — Adjusts automatically based on temperature
- High — Maximum cooling for extended shoots
- Silent — Fan stops for sound sensitive environments (output reduced to 10–20W)
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.

Verdict final
The GVM PF100B delivers professional flexibility in a compact package. With 15°–45° beam adjustment, 2700K–6800K bi-color range, 97+ CRI/TLCI, 30,200 lux output, and silent operation, it adapts to whatever you‘re shooting — product photography, interviews, portraits, or run and gun video work.
It replaces a bag of modifiers with a single twist of a knob. For creators who need versatility without the bulk, the PF100B is a practical choice.
FAQ
Q1: What is a focusable LED video light, and how is it different from a regular LED panel light?
A focusable LED video light uses a built-in optical Fresnel lens that lets you adjust the beam angle by turning a knob. Regular LED panel lights have a fixed beam and cannot precisely control the light spread. With a focusable light like the GVM PF100B, you can smoothly transition from a 15° spot to a 45° flood — spot mode delivers a concentrated, punchy beam for product highlights or dramatic effects, while flood mode provides soft, even illumination for interviews and portraits. One focusable light replaces multiple fixed-beam lights plus a bag of modifiers.
Q2: Is the Silent Mode on the GVM PF100B truly silent? Are there any trade-offs?
Yes, in Silent Mode the cooling fan stops completely, producing zero noise — ideal for interviews, podcasts, and dialogue-heavy shoots. However, the trade-off is that output drops to approximately 10–20W, significantly reducing brightness. For close-up shots or quiet environments where audio quality is critical, Silent Mode works perfectly. For longer distances or brighter output, Smart Mode (which adjusts fan speed automatically based on temperature) offers a good balance between brightness and noise.
Q3: Is 30,200 lux bright enough for real-world shooting?
30,200 lux (spot mode @ 1m) is respectable for a 100W compact light. In practice, it’s sufficient for:
- Photographie de produit: Close-up shots of small items, even with a softbox attached
- Portrait fill: As a key light or rim light indoors
- Video interviews: As a key light in controlled indoor settings However, if you need to light a large scene or shoot from a significant distance, 100W will feel limited. That’s by design — the PF100B prioritizes portability and versatility over raw power.
Q4: What is a Mini Bowens mount? Can I use standard Bowens accessories?
Mini Bowens mount is a scaled-down version of the standard Bowens mount, designed for compact fixtures. This means standard-size Bowens softboxes, beauty dishes, and other modifiers cannot be directly attached to the PF100B. You will need accessories specifically designed for the Mini Bowens mount, or use an adapter ring to fit standard modifiers. Check compatibility with your existing gear before purchasing, or choose GVM’s dedicated Mini Bowens accessory lineup.
Q5: Who is the GVM PF100B best suited for? Is it beginner-friendly?
The PF100B is ideal for:
- Photographers: Needing one light for both product detail shots and portraits
- Filmmakers & videographers: Requiring bi-color range and silent mode for interviews and narrative work
- Podcasters and streamers: Silent operation ensures clean audio
- Travel creators: At 1.53 kg, it’s genuinely portable for on-location shoots For beginners, the PF100B is very user-friendly — no complex modifier assembly, just turn the focus knob to change the light effect. However, if your budget is tight and you mainly shoot static products, a higher-wattage non-focusable light (like a 300W COB monolight) may offer better value for pure brightness. The PF100B’s core strength is polyvalence, not maximum output.
