Review on GVM Video Continuous Spotlight Photography by Renee White

They're really cheap and they love it BUT. Both the ones I got show the same light output and it's slightly higher than the rating given in the specs. I'm not trying to fit my honeycomb grid into the reflector, but I'm pretty sure it won't fit because I don't have the flat "edge" that all my other reflectors have. The Bowens mount fits all of my accessories, although they are quite loose. even if"blocked". None of them hang around with any of my Bowens flashes. It looks like the airflow is designed to exit around the mounting ring, so that could be the problem. The van runs VERY quietly on it. (Something that is a problem with many cheap LED tubes when recording A/V). They are very light, but that also makes them feel cheap. I'm not picky about my gear, but if you're demanding it might not be enough on the road. I ran them at 100% load for over an hour and they felt very warm (metal heatsinks around the LED). I should have taken my temperature, but it was in the hot "coffee" range. Maybe a little bit more. If these are the latter, I will be very happy. I made a DC power supply for them: Evercool Fan 45x45x10mm 3pin 12v Fan EC4510M12CAGowoops 2PCS 150W DC-DC 10-32V to 12-35V Step Up Boost Converter Adjustable Module Supply Voltage Deep Cycle AGM Battery 35Ah It doesn't seem like a good cheap one to give bright LED solution for DC video lighting.
