Godox VL150 150W LED COB Light - Lab Review

Godox VL150 – Technical Analysis

The Godox VL150 is a 150 W daylight COB light with a fixed colour temperature of 5600K. Measurements were taken at a distance of 1 m without modifiers, plus one measurement with the standard reflector, across a total of 4 individual measurements.

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 (45,949 lux).

🔎 Performance Analysis

💡 Light Output

Unmodified, the VL150 delivers 5,049 lux at a distance of 1 m (EV 11.0). With the standard reflector, output rises to 45,949 lux (EV 14.2), roughly nine times the bare value. Relative to its 150 W, that is one of the strongest reflector results in our database and the reason for the very high power score of 129.1.

Dimming is almost perfectly linear, and the colour temperature hardly moves across the dimming range:

Between 10% and 100%, the CCT changes by less than 1 MK-1. Since the VL150 only offers one colour temperature, there are no output differences between CCT settings to plan around.

Standout Features:

• ✅ Very high output with reflector: 45,949 lux, power score 129.1
• ✅ Linear dimming: 10% power ≈ 11% light, 50% ≈ 51%
• ✅ Stable colour across the dimming range: under 1 MK-1 between 10% and 100%
• ⚠️ Moderate bare output: 5,049 lux; the full potential only shows with a focusing reflector

🎨 Colour Rendering (White Light)

CRI (Ra) reaches 96.9 and R9 96, so skin tones and saturated reds are rendered cleanly. R9 stays at 95 to 96 even at 10% and 50%. TLCI (for information) is 97.

TM-30 is more modest with Rf 92 and Rg 101. Saturation is natural overall, but fidelity is somewhat lower than the high CRI suggests (see TM-30 in detail). The SSI of 70 is typical for phosphor-converted daylight LEDs: solid for content and studio work, but not at the level of high-end cinema lights.

Standout Features:

• ✅ High CRI and R9: Ra 96.9, R9 96
• ✅ Natural overall saturation: Rg 101
• ⚠️ Moderate TM-30 fidelity and SSI: Rf 92, SSI 70

🧪 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.

The VL150 shows a clear daylight pattern: purple is rendered around 10% more saturated, and blue-violet follows with +5%. Yellow, on the other hand, is slightly desaturated (-4%). The weak point is the cyan range: local fidelity drops to 85 in cyan and 83 in cyan-blue, and blue-green to cyan-blue tones also show a noticeable hue shift (up to 0.10). That is why 28 of the 99 colour samples fall below Rf 90, and the weakest one only reaches 67.

In practice, this matters for turquoise, teal and cyan product colours, which can look slightly off, and for purple fabrics or flowers, which appear more intense than in reality. Skin tones are hardly affected: the orange-red and orange bins (2 and 3) show no saturation shift and reach Rf,h 96 and 94.

The spectrum peaks at 453–454 nm (blue pump), as is typical for phosphor-converted daylight LEDs.

Standout Features:

• ✅ Skin tones unaffected: bins 2/3 without saturation shift, Rf,h 94–96
• ⚠️ Weaker in cyan: Rf,h 83–85 in bins 10/11, hue shift up to 0.10
• ⚠️ Purple oversaturated: +10% in bin 15

🌡️ CCT Accuracy

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

At 5,816 K, the VL150 is slightly cooler than its nominal 5600K. With 6.63 MK-1, the deviation stays below the threshold of around 10 MK-1 at which a shift becomes perceptible. The lab report evaluates the light against a 5500K target, which results in 9.88 MK-1 there.

The Duv value of -0.0017 means a minimal, practically invisible magenta tendency. At 10% and 50%, Duv is even closer to zero (-0.0003 and -0.0007).

Standout Features:

• ✅ Good CCT accuracy: 6.63 MK-1 against 5600K
• ✅ Neutral white point: Duv -0.0017
• ✅ Very stable across dimming: 5,793 to 5,816 K

✅ Strengths

1. Very high output with reflector → 45,949 lux with the standard reflector, power score 129.1
2. High CRI and R9 → Ra 96.9, R9 96, natural skin tones
3. Linear dimming without colour shift → 10% power ≈ 11% light, under 1 MK-1 CCT change between 10% and 100%
4. Good, neutral white point → 6.63 MK-1 against 5600K, Duv -0.0017
5. Simple operation → One colour temperature, no output differences between settings

⚠️ Weaknesses

1. Only one colour temperature → No flexibility for warm or mixed lighting moods
2. Weaker cyan rendering → Rf,h 83–85 in cyan and cyan-blue, 28 of 99 colour samples below Rf 90
3. Medium SSI → 70 is solid but not high-end
4. Moderate output without reflector → 5,049 lux bare; large, soft modifiers use much less of the potential

📉 Practical Applications

Ideal for: → Interviews, portraits, small studios: high CRI/R9, natural skin tones, linear dimming → Daylight key light with reflector: very high output for the power class → Content creation: YouTube, streaming, social media

Use with caution: → Spectrally sensitive work: SSI 70, TM-30 Rf 92 → Products in turquoise, teal or purple: visible deviations in the cyan and purple range → Large, soft modifiers: bare output is only moderate → Variable white balance: only 5600K available

📌 Conclusion

The Godox VL150 is a reliable daylight COB light with high CRI and R9 (96.9 and 96), linear, colour-stable dimming and very high output with the standard reflector (45,949 lux). It is ideal for setups where daylight, ease of use and plenty of punch matter most.

The detailed TM-30 analysis puts the high CRI into perspective: skin tones are rendered cleanly, but cyan and turquoise lose fidelity, and purple is oversaturated. For portraits, interviews and most content work, that hardly matters. For spectrally critical tasks and colour-critical product work in these hues, there are better options; for many studio and content applications, the VL150 remains a safe and very powerful choice.
