GVM Pro SD400B Bi-Color Studio LED Monolight (V-Mount)

The GVM Pro SD400B is a 400-watt bi-color COB LED monolight built for professional video productions and photography studios where maximum light output and precise color control are essential. Delivering up to 69,400 lux at one meter, it provides a sun-like intensity in a compact, studio-ready fixture — powerful enough to shoot through large softboxes, beauty dishes, and heavy light modifiers.

Key specifications:

• 400W COB output — 69,400 lux at 1 meter for powerful output through large modifiers
• Bi-color range: 2700K–6800K with 1000-step dimming from 0.1% to 100% for smooth, flicker-free brightness control critical in video
• CRI 97+ for natural, accurate color rendering across all subjects — skin tones, product colors, and fine textiles
• Standard Bowens mount for compatibility with softboxes, reflectors, beauty dishes, and other modifiers you already own
• Rainproof design (IP-rated) — suitable for outdoor location shoots in light rain without protecting the fixture
• V-Mount battery compatible (AC and battery power) — go fully wireless for location shoots
• App and DMX control — integrate into professional lighting rigs or control remotely via iOS and Android
• 12 scene modes — simulate lightning, candlelight, TV, fire, and other practical lighting effects
• Ultra-quiet dual cooling fans — below 40 dB so the set stays quiet during dialogue recording

The SD400B is suited for portrait studios, commercial productions, film sets, and any application where you need serious light output with the color accuracy and control to match. Its Bowens compatibility makes it a natural extension of your existing modifier collection.
