The Nanlite Forza 300B and the Godox SL300III Bi are both bi-color LED monolights in the same general power class, built for video, interviews and studio photography. They overlap heavily, so the better choice comes down to the ecosystem you already use, the controls you like, and the exact specifications you confirm on each maker’s page.
What Each Light Is For
Both lights are compact COB-style LED heads designed to replace a small tungsten or HMI-style source. You can shape their output with reflectors, softboxes and lanterns, and both can run from a mains adapter on a stand.
Nanlite positions the Forza line as a compact, field-friendly series, and the 300B is the bi-color version that lets you shift color temperature between warm and cool. Godox offers the SL300III Bi as a bi-color studio light that fits into its wide range of lighting accessories.
Key Differences to Check
| Area | What to compare |
|---|---|
| Output and color range | Maximum brightness and the warm-to-cool range, as stated by each maker |
| Power options | Mains only, or battery use through adapters or plates |
| Control | On-body dials, app control and wireless protocols |
| Mount and modifiers | Which mount style the head uses and which softboxes fit |
| Fan noise | Cooling design and whether a quiet mode is offered |
| Weight and size | Head weight on a stand and on a boom |
We have not used either light ourselves, and we are not listing numbers here, since specifications can change between production versions. Check the maker’s current product page.
How to Decide
- Begin with your modifiers. If you already own softboxes or reflectors in one mount style, favor the light that accepts them without adapters.
- Think about your shooting location. Studio work with wall power is simple. Location work may need battery plates or a portable power source.
- Consider fan noise. Interviews and dialogue scenes benefit from a quiet mode, so look at what each maker says about it.
- Match the control system. If your other lights use one maker’s app or remote, staying inside that system keeps control simple.
- Check service and spare parts. Look at warranty terms and local support in your region.
Practical Tips
- Pair either light with a softbox or lantern for flattering, soft output on faces.
- Keep the head away from walls and fabric so the cooling vents can breathe.
- Use a sturdy stand with a sandbag, since a head with a large modifier is top-heavy.
FAQ
Can these lights replace flash for portraits?
They can for many setups, since continuous light lets you see the result as you shoot. Flash still offers more power for freezing motion and overpowering daylight.
Is a bi-color light better than a single-color light?
Bi-color gives flexibility to match daylight, tungsten or mixed sources. A single-color light can be a simpler choice if you always work in one color temperature.
The Short Version
These two lights are close rivals, so choose by ecosystem, mount compatibility, control style and noise behavior rather than by name. Confirm current specifications on each maker’s page before buying.
