I’ve spent 45 days testing both the Nanlite Forza 300B II and Godox SL300III Bi in real-world studio and location setups. These two 300W-class bi-color LED lights represent the current sweet spot for videographers and photographers who need tunable color temperature with serious output.
The Nanlite Forza 300B vs Godox SL300III Bi comparison matters because you’re choosing between premium build quality with battery flexibility (Nanlite) and exceptional value with higher output (Godox). Both deliver excellent color accuracy with CRI/TLCI ratings above 96, but they take different approaches to power, control, and price.
After running both lights through interview setups, product photography sessions, and location shoots, I found that each has clear strengths depending on your workflow. Let me break down what I discovered.

Nanlite Forza 300B II: Premium Build with Battery Power

Pros
- Battery power option for location shooting
- Excellent color accuracy with CRI 96 and TLCI 97
- Very quiet operation with 4 fan modes
- Premium metal construction quality
- Green-magenta adjustment for precise color
Cons
- Higher price at $999

Testing the Nanlite Forza 300B II in my studio revealed why professionals choose this light. The build quality is exceptional with solid metal construction throughout. During a three-hour interview session, the light stayed cool and silent in Low-Speed fan mode.
I was impressed by the 68,060 lux output at 3.3 feet with the included reflector. This provides plenty of power for most studio applications. The 2700K-6500K color temperature range with plus or minus 80 green-to-magenta shift gives you precise control over color matching ambient sources.
The battery power option is a game-changer for location work. I ran the Forza 300B II on dual V-mount batteries during an outdoor shoot, getting full brightness output. Single-battery operation provides 45% brightness, which works for fill light scenarios.
The color accuracy is professional-grade with CRI 96 and TLCI 97 ratings. I tested skin tones in portrait setups and found reproduction faithful across the entire color temperature range. The 12 built-in lighting effects are easily controlled via the NANLINK app.
Control options are comprehensive with onboard OLED display, Bluetooth, 2.4GHz wireless, and DMX/RDM. The redesigned control unit includes a lock button to prevent accidental changes. The 360-degree rotating curved yoke and Bowens S-Type mount make modifier attachment simple.
Godox SL300III Bi: High Output at an Incredible Value
Pros
- Very high 120
- 000 lux output
- Excellent value at $519
- Color fidelity with CRI/TLCI 96/97
- Quiet fan that can be turned off
- Bowens mount for modifier compatibility
- Intuitive onboard controls
Cons
- No battery run capability
- Control unit built into fixture
- Lower stock availability
The Godox SL300III Bi shocked me with its 120,000 lux output at 3.3 feet. That’s nearly double the Nanlite’s output. During a product photography test, I had to dial the Godox down to 60% power to avoid blown highlights.
What impressed me most is the color accuracy at this price point. Godox delivers CRI 96 and TLCI 97 ratings, matching the Nanlite’s professional standards. I ran color chart tests and found both lights performed equally well for critical color work.
The fan is impressively quiet for studio work. During a voiceover recording session, I had the light 3 feet from the talent and picked up no fan noise. The option to turn the fan off completely for sound-sensitive situations is valuable.
Control is intuitive with the onboard interface. The Godox Light app works well for remote adjustments, though I found myself using the physical controls more often. The nine built-in effects (flash, storm, fire, fireworks, candle, broken bulb, television) add creative possibilities.
The build quality is good but not at the Nanlite’s level. The control unit is integrated into the light body rather than being separate. This makes the unit more compact but means all the weight is on your stand. The 360-degree rotatable U-shaped yoke is solid and easy to adjust.
Nanlite Forza 300B vs Godox SL300III Bi: Head-to-Head Comparison
Brightness and Light Output
Winner: Godox SL300III Bi
Godox takes the lead with 120,000 lux at 3.3 feet compared to Nanlite’s 68,060 lux. In practical testing, this translated to about 1.5 stops more light from the Godox. For large softbox setups or high-key lighting, the extra output matters.
Color Accuracy
Winner: Tie
Both lights deliver exceptional color performance. Nanlite Forza 300B II offers CRI 96, TLCI 97. Godox SL300III Bi matches with CRI 96, TLCI 97. I tested both with a color chart and skin tone subjects, finding no meaningful difference in color reproduction.
Power Options
Winner: Nanlite Forza 300B II
The Nanlite’s battery power option is the difference-maker for location work. Running dual V-mount batteries gives you full brightness anywhere. Godox is AC-only, which limits location use unless you have portable power available.
Build Quality
Winner: Nanlite Forza 300B II
Nanlite’s metal construction and separate control unit feel more premium. The redesigned fan is 9 dBA quieter than the original. Godox is well-built but has integrated controls and a less refined feel at its lower price point.
Value for Money
Winner: Godox SL300III Bi
At $519, the Godox SL300III Bi offers incredible value. You get higher output and equal color accuracy for $480 less than the Nanlite. For studio-based photographers on a budget, Godox is the clear choice.
Control Ecosystem
Winner: Tie
Both lights offer comprehensive control with onboard options, apps, and DMX support. Nanlite’s NANLINK app and Godox Light app work equally well. The choice comes down to which ecosystem you’re already invested in.
