    @Sph1nxster

    This one do not know, sorry. They do not have dealer as it seems.

    We'll do more measurements, but for now controller behavior looks little strange.

    Like M9 it can't keep up output, but it also have sudden jumps.

    GVB Gear GVBPL12 (Daylight model), 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.

    GVB Gear GVBPL12 is quite good light with light quality suitable for videos.
    Light tends to be slightly cooler than 5500K.

    More complete brightness during discharge, it is much brighter than Aputure M9

    But same approach used by controller - more life but with cost of falling brightness.

    image

    Compare to M9

    image

    Better brightness due to more and larger leds used

    GVB PL12 PWM at 100% (battery at not full fresh charge)

    image

    You can see that controller dims leds even at 100%.

    See above that controller can't keep output level.

    PWM Frequency is 43,45Khz

    GVB PL12 PWM at around 25% (battery at not full fresh charge)

    GVB PL12 Inside

    Light has simple and cheap design, but better than Aputure M9.

    Wheel used here is much more handy for adjustments and will live longer.
    Front led board has large vertical holes for inside ventilation.

    image

    Battery and strange empty space inside

    manufacturer decided to put empty space with some little vent holes.
    It is not much efficient and take lot of space from battery that could be larger.

    image

    Main board

    Soldering is not top notch here. Plus board is unnecessary crowded.
    Lot of space is left between board and battery to make proper design and to not have battery wires solder points so densely placed.
