Nanlite Forza 60c 60W RGB Led COB Light- Lab Review

Nanlite Forza 60C – Technical Analysis

The Nanlite Forza 60C is a compact RGB COB light. The measurements cover white light from 1800K to 6500K at a distance of 1 m without modifiers, plus one measurement with the standard reflector, across a total of 9 individual measurements. RGB mode was not part of this measurement series, so there is no RGB score.

Scores and lab report based on the current version of our evaluation (October 2026). The power score refers to the output with the standard reflector (12,691 lux).

🔎 Performance Analysis

💡 Light Output

Between 3200K and 6500K, the Forza 60C delivers very even output: 5,017 to 5,134 lux at a distance of 1 m (EV 11.0), a spread of only about 2%. Even at 1800K, it still reaches 4,066 lux, about 21% less. For a compact RGB light, that is a strong and very predictable result.

With the standard reflector, the light reaches 12,691 lux at 5500K (EV 12.3). That is only about 2.5 times the bare output, a relatively small focusing effect.

The dimming curve is slightly lifted:

At 10%, the 60C still delivers about 13% of its maximum, at 50% about 54%. The colour temperature also shifts with brightness: at 3200K by about 8 MK-1 (from 3,197 K to 3,113 K), at 5500K by about 5 MK-1. In both cases, the light gets warmer as brightness increases.

Standout Features:

• ✅ Very even output from 3200K to 6500K: about 2% spread
• ✅ Strong output at 1800K: 4,066 lux
• ⚠️ Small reflector gain: 12,691 lux, about 2.5 times the bare output
• ⚠️ Lifted dimming curve with CCT shift: 10% ≈ 13% light, up to about 8 MK-1

🎨 Colour Rendering (White Light)

CRI (Ra) is high at 96.5 to 98.1, with a peak at 3200K. R9 reaches 97 at 3200K and 92 to 93 in daylight, only 1800K is somewhat lower at 87. At 5500K, R9 even stays at 97 at 10% and 50%. TLCI (for information) reaches 96 to 97 from 3200K upwards, but only 83 at 1800K.

TM-30 Rf lies between 93 and 94 from 3200K upwards, with Rg 102. At 1800K, Rf drops to 90 while Rg rises to 109: this setting renders colours clearly more saturated (see TM-30 in detail).

The SSI is 80 at 1800K and 79 at 3200K, and drops to 69 at 5500K and 65 at 6500K. The daylight values are moderate and matter when matching with high-quality daylight sources.

Standout Features:

• ✅ High CRI: Ra 96.5–98.1
• ✅ Very good red rendering at 3200K: R9 97
• ⚠️ Daylight SSI moderate: 69 at 5500K, 65 at 6500K
• ⚠️ 1800K strongly saturated: Rg 109, TLCI 83

🧪 TM-30 in Detail

TM-30 divides colours into 16 hue bins. The local chroma shift (Rcs) shows whether a hue is rendered more or less saturated than under the reference light, the local fidelity (Rf,h) how accurately it is rendered overall. Shifts of a few percent are barely visible; from around 10%, the affected hues look noticeably more intense or duller.

1800K behaves very differently from the other settings. Yellow-orange (+9%), yellow (+11%), yellow-green (+13%) and green (+7%) are rendered clearly oversaturated. Violet and blue-violet also shift noticeably in hue (up to -0.19), and local fidelity drops to 80 in yellow-green and 81 in violet. 40 of the 99 colour samples fall below Rf 90. The result is a warm, very saturated look, which suits candlelight or sunset moods, but is not a neutral reproduction.

From 3200K upwards, the 60C behaves like a classic white light. At 3200K, all hue bins stay within ±6%, with blue (+6%) and violet (+5%) slightly emphasised. At 5500K and 6500K, the typical daylight pattern appears: purple (+9%) and violet (+12%) become more saturated, while fidelity in cyan-blue drops to 85–87.

Skin tones in the orange-red and orange bins (2 and 3) reach Rf,h 95 to 98 from 3200K upwards. At 1800K, orange drops to Rf,h 86 and is rendered about 4% more saturated.

In the warm settings, the spectrum peaks at 645–647 nm, noticeably further into the red than with typical phosphor white LEDs. That points to a dedicated red channel in the colour mix and fits the high R9 of 97 at 3200K. In the daylight settings, the peak sits at 451–453 nm (blue pump).

Standout Features:

• ✅ Balanced at 3200K: all hue bins within ±6%, Rf,h ≥ 90
• ✅ Skin tones stable from 3200K: bins 2/3 at Rf,h 95–98
• ⚠️ 1800K strongly oversaturated: yellows and greens up to +13%, 40 samples below Rf 90
• ⚠️ Daylight pattern: violet +12% at 6500K, cyan-blue Rf,h 85

🌡️ CCT Accuracy

The deviation in Mired (MK-1) is more meaningful than the raw Kelvin difference, since the Kelvin scale is not linear:

All colour temperatures stay below the threshold of around 10 MK-1 at which a shift becomes perceptible. 1800K and 5500K are precise (3.68 and 4.67 MK-1). 3200K is slightly warmer than set at 3,113 K, 6500K slightly cooler at 6,897 K; both are close to 9 MK-1.

Duv is slightly negative at every colour temperature (-0.0016 to -0.0030), meaning a very slight magenta tendency. In practice, that is barely visible, but it is consistent across all settings.

Standout Features:

• ✅ All CCTs below 10 MK-1: 3.68 to 8.86 MK-1
• ✅ Precise at 1800K and 5500K: 3.68 and 4.67 MK-1
• ⚠️ Slight magenta tendency at every CCT: Duv -0.0016 to -0.0030

✅ Strengths

1. Very even output across CCTs → 5,017 to 5,134 lux from 3200K to 6500K, 4,066 lux even at 1800K
2. High colour fidelity → Ra 96.5–98.1, R9 97 at 3200K
3. Wide white range → From 1800K to 6500K, all CCTs below 10 MK-1
4. Stable skin tones from 3200K → Bins 2/3 at Rf,h 95–98
5. High usability score → 78.3

⚠️ Weaknesses

1. Daylight spectrum → SSI 69 and 65, violet up to +12%, cyan-blue Rf,h 85
2. Small reflector gain → 12,691 lux with the standard reflector, about 2.5 times the bare output
3. Lifted dimming curve with CCT shift → 10% ≈ 13% light, up to about 8 MK-1 at 3200K
4. 1800K not neutral → Rg 109, yellows and greens up to +13%, TLCI 83
5. Slight magenta tendency → Duv negative at every CCT

📉 Practical Applications

Ideal for: → Interviews and content at 3200K: high CRI, R9 97, stable skin tones → Multi-light setups with mixed CCTs: almost identical output from 3200K to 6500K → Warm, atmospheric looks at 1800K: candlelight or sunset moods → Mobile productions: compact RGB light with high usability

Use with caution: → Neutral reproduction at 1800K: strongly oversaturated yellows and greens → Spectrally demanding daylight work: SSI 65–69 → Long throws with a reflector: small focusing effect → Precise exposure control at low levels: lifted dimming curve

📌 Conclusion

The Nanlite Forza 60C is a compact RGB COB light with very even output across colour temperatures, high CRI values and a wide white range from 1800K to 6500K. Its best white setting is 3200K, where CRI 98.1, R9 97 and a balanced TM-30 profile come together.

The detailed analysis shows two characteristics to be aware of: 1800K renders yellows and greens strongly oversaturated, which suits atmospheric looks but not neutral work, and the daylight settings show the usual oversaturation in violet and purple with an SSI of only 65 to 69. With its small reflector gain and lifted dimming curve, the 60C is a flexible, colour-accurate light for content, interviews and creative setups, but not a daylight reference.
