The landscape of portable lighting for independent filmmakers, documentary crews, and mobile content creators is undergoing a rapid technological evolution. As cameras become smaller and more light-sensitive, the demand for highly portable, color-accurate, and power-efficient illumination sources has reached an all-time high.
In a significant move to capture this highly competitive segment, SWIT has announced the Mini-150B, a 150-watt bi-color Chip-on-Board (COB) LED light designed to challenge existing power-to-size benchmarks in the professional lighting industry.
Executive Overview
The SWIT Mini-150B represents a deliberate engineering effort to condense high-output, color-precise lighting into a form factor that fits comfortably in the palm of a hand. Measuring just 103 x 103 x 124 mm (approximately 4 x 4 x 5 inches) and weighing a mere 1.0 kg (2.2 lbs) bare, this fixture delivers a true 150W bi-color output. It targets a broad demographic of visual storytellers, including:
- Documentary and News Crews: Requiring rapid deployment, minimal footprint, and battery-powered versatility.
- Corporate Videographers and Event Teams: Demanding high color fidelity and seamless integration into fast-paced corporate environments.
- Podcasters and Livestream Studios: Needing silent operation, flicker-free dimming, and app-based remote control.
- Rental Houses: Looking to build ultra-compact, high-density lighting kits for traveling cinematographers.
What distinguishes the Mini-150B from its competitors is its unique dual-array power management system. While traditional bi-color fixtures often compromise on output at the extreme ends of their color temperature range, the Mini-150B maintains its full rated output from 2700K to 6500K.
Equipped with a native, on-board V-mount battery plate, versatile USB-C Power Delivery (PD) inputs, and an adaptable Mini Bowens accessory mount, this fixture represents a highly integrated solution designed to eliminate external ballasts, dangling cables, and complex rigging.
Detailed Chronology & Design Philosophy
The development of the Mini-150B highlights a broader industry trend: the transition away from bulky, multi-component lighting fixtures toward highly integrated, single-body systems. Historically, a 150W fixture required an external ballast, a heavy mounting bracket, and proprietary cabling, which added weight and failure points to a lighting setup.

+---------------------------------------------------------+
SWIT’s engineering team approached the Mini-150B with the goal of eliminating these pain points. By integrating the power control circuitry, the thermal management array, and a native V-mount receiver directly into the light head, SWIT has achieved one of the highest power-to-size ratios in the 150W bi-color class.
Mechanical Architecture and Thermal Management
To pack 150 watts of LED power into a 10-centimeter cube without causing thermal throttling or premature component failure, SWIT developed a highly efficient active cooling system.
The chassis features a multi-directional airflow design coupled with a low-noise brushless fan. The light is rated for continuous full-power operation under standard operating temperatures, supported by an intelligent thermal sensor array that monitors the COB emitter and regulates fan speed dynamically.
Dual-Array LED Configuration
To achieve consistent brightness across the color spectrum, the Mini-150B utilizes two completely independent LED arrays: a 150W array dedicated to 2700K (warm tungsten) and a 150W array dedicated to 6500K (cool daylight).

Instead of splitting the power budget between the two arrays—which typically results in a drop in output at the warm and cool limits—the onboard microcontroller intelligently mixes the power delivery. This ensures that whether the user is shooting at 3200K, 5600K, or any point in between, the fixture delivers its full rated wattage.
Supporting Context & Technical Metrics
An analysis of the Mini-150B’s photometrics, color science, and electrical architecture reveals a fixture built to meet stringent professional standards.
Photometric Performance and Color Fidelity
When paired with its standard optimized reflector, the Mini-150B delivers an impressive 24,000+ lux at a distance of 1 meter (measured at 5600K). This provides ample output for bouncing off ceilings, punching through diffusion silks, or keying talent in high-ambient-light environments.
| Metric | Rating / Value | Significance for Cinematographers |
|---|---|---|
| CRI Ra | 98 | Superior reproduction of skin tones and subtle color gradations. |
| TLCI | 98 | Minimizes post-production color correction times for broadcast and digital cinema. |
| R9 (Saturated Red) | >90 (2700K – 5600K) | Critical for natural, healthy-looking skin tones and organic textures. |
| TM-30 Rf (Fidelity) | >92 (Across range) | Ensures highly accurate spectral distribution compared to natural light sources. |
| CCT Tolerance | Within ±2% (50K steps) | Drastically tighter than the ±5% industry norm, preventing color shifts between fixtures. |
| Output Stability | 0.4% flux variation | Prevents noticeable brightness drifting over hours of continuous operation. |
Advanced Dimming and Power Modulation
The Mini-150B addresses the critical issue of high-speed camera flicker. Utilizing a 20 kHz Pulse-Width Modulation (PWM) frequency, the light remains completely flicker-free at any frame rate or shutter angle, making it ideal for high-speed slow-motion videography.
The dimming engine allows control from 0% to 100% in 1% increments, boasting an ultra-fine 0.1% resolution for low-light scenarios. To suit different shooting styles, users can select from four distinct dimming curves:
- Linear: Proportional adjustment across the entire range.
- Logarithmic: Enhanced control in the lower end of the dimming range.
- Exponential: Finer adjustments at the higher end of the output spectrum.
- S-Curve: A balanced curve offering smooth transitions at both the bottom and top of the range.
Power Input Versatility and "Turbo Mode"
The power delivery architecture of the Mini-150B is highly adaptable, designed to handle three distinct power sources without requiring external adapters:

[V-Mount Battery] [USB-C PD Port] [AC Wall Power]
- Native Plate - PD 3.0/2.0 - Via UC-150 Adapter
- Turbo: 150W - 90W (100W PD) - 110W (100-127V)
- Continuous: 110W - 50W (65W PD) - 120W (220-240V)
- 40W (45W PD)
- On-Board V-Mount Plate: The rear of the light features a native V-mount plate that accepts standard V-mount batteries directly. When powered by a battery with a voltage above 13V, the light can engage Turbo Mode, unlocking the full 150W output. In standard Continuous Mode, the light draws a constant 110W. Using a compact 99Wh battery (such as the SWIT OMNI-99S), the light can run at its full 150W capacity for approximately 40 minutes of uninterrupted operation.
- USB-C Power Delivery (PD): The integrated USB-C input is compatible with PD 3.0, PD 2.0, Samsung AFC, and Quick Charge (QC) 2.0/3.0 protocols. The light automatically negotiates power draw based on the connected charger:
- 100W PD Adapter: Yields up to 90W of output.
- 65W PD Adapter: Yields up to 50W of output.
- 45W PD Adapter: Yields up to 40W of output.
The USB-C input accepts 15V, 20V, and 28V power rails, allowing the fixture to run off standard laptop chargers or high-capacity power banks.
- AC Mains Power: Utilizing the optional UC-150 AC-to-USB-C adapter, the light can run continuously off wall power. It delivers up to 110W on standard 100-127V mains (typical of North America) and up to 120W on 220-240V mains (typical of Europe and Asia).
Acoustic Performance and Silent Mode
For sound-sensitive environments like intimate podcast studios or quiet documentary interviews, fan noise is a critical concern. The Mini-150B offers dual cooling profiles:
- Passive Fan-Off Mode: Operates in absolute silence (0 dBA) by disabling the active cooling fan. To protect the LED, output is limited to 30W, and this mode requires a 24V+ input source (such as the UC-150 AC adapter).
- Active Cooling Mode: When the fan is engaged, the acoustic footprint is kept remarkably low. On AC power, the fan operates below 30 dBA at low and medium speeds. On battery power, noise levels range between 36 to 38 dBA, and peak at approximately 42 dBA when running at maximum high-speed cooling.
Official Statements & Manufacturer Intent
In design documentation and product briefings, SWIT emphasizes that the Mini-150B was conceived to address the practical limitations of "ultra-portable" lights currently on the market. Many competing pocket-sized COB lights rely on external power bricks, delicate proprietary mounting rings, or fragile plastic casings that fail under the rigors of daily field production.
SWIT’s design team focused heavily on build quality and ecosystem integration. By utilizing a ruggedized chassis and incorporating a Mini Bowens mount, SWIT provides a secure, compact bayonet system for dedicated travel modifiers.
Crucially, recognizing that professionals already own a vast array of light shaping tools, SWIT includes a Mini to Standard Bowens adapter in the box, allowing users to instantly mount full-sized softboxes, beauty dishes, and projection attachments without needing to reinvest in a new ecosystem.

Furthermore, SWIT has integrated the fixture into its modern wireless control ecosystem. The onboard rear display provides clear, high-contrast readouts of intensity, CCT, battery life, fan status, and wireless channel selection.
For larger-scale productions, the SWIT Console app for iOS and Android utilizes a robust Bluetooth Mesh network. This allows gaffers and directors of photography to group multiple fixtures, trigger pre-programmed lighting effects (such as lightning, television flicker, paparazzi flash, and faulty bulb), save scene presets, and perform over-the-air firmware updates to ensure long-term compatibility and feature expansion.
Future Outlook & Market Impact
The announcement of the Mini-150B positions SWIT to capture a significant share of the mid-tier, high-portability lighting market.
