Aputure 300X Bi-Color Light

  • Aputure 300X (Daylight setting), Measurement using CV600, Russian Lab processing

    We cover spectrum, color temperature, and all modern color quality standards, including latest 2016 and 2017 years ones.

    Never select light based on just CRI number.

    Focus on TM30 and CIE 224 and look for color distortion and Rf values.

    300X is good light with light quality suitable for videos. But nothing to write home about, on par or even worse with typical cheap Chinese COB lights now.

  • In maximum-output mode, the 300X develops around 9000lx at 2800K and 11500lx at 6500K. Cooler LEDs tend to have higher output since they’re converting less of the blue emitter, and this is normal. In maximum-output mode, the 4200K setting achieves perhaps 16000lx. That’s still less than a 300D at full power, but not unreasonable given the involvement of warmer-tuned emitters. Selecting constant-output mode drops the 4200K setting to around 8500lx, more or less as we’d expect. It’s always the case that constant-output mode will noticeably limit output in the middle and cooler ranges, and Aputure’s menu option makes sense.

    At no time does TLCI fall below 91.2, and even then it’s at the difficult 5% output level, which also provokes the poorest R9 reading at a still-fine 79. At 50% output, lowest TLCI is 97.3 and R9 remains at 80, even at the cooler end of the CCT range. At 3200K, which tends to be easier to get right, the 300X achieves 98.4 TLCI, 93 R9, and 90 R12.
