I ordered 3 of these and they showed up today - really nice/small/portable and they're surprisingly bright at full strength. They come in cute little pouches with clips too. I think they might work as the beginning of a really small portable lighting kit for my A7s and/or A7rII, potentially combined with Lumecubes (I have a small handful of them on the way too).

The M9's feel light enough that they could easily be attached to things with moderately-strong tape if one didn't want to bring with a bunch of light stands to go with them (though the next step is figuring out what can be done for really tiny light stands - a few small gorillapods might be a place to start)

Check out my review of this light. The Aputure Amaran AL-M9

Thanks for good video.

PV Lab measurements, CV600 spectrometer, 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 244 and look for color distortion and Rf values.

AL-M9 is very good little light with good light quality.

This is exactly my problem. In my opinion, it makes the light useless for anything other than very short takes, yet no-one else seems to mention this in their reviews!

Aputure M9 PWM at 100% (battery at not full fresh charge)

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

See above that controller can't keep output level.

PWM Frequency is 39,8Khz

Most hot parts are solid middle lines of led board and also controller board near USB connector.
