Exploring an eBay "mine" light (flicker alert)

I was trying to make this video quickly before travelling with work, so there are a couple of rogue slip-ups. I'm not sure why I managed to say the LEDs were in parallel when in reality there are a large number of LEDs in series per section (which to be fair are then wired as three sections in parallel). Each LED has two chunky LED chips in them. I also said the big light was 100W when it's rated at 300W as shown in the tests.
These lights are both from eBay. They're based on the very common linear regulator chips with no smoothing that results in significant flicker. Not a huge issue for ambient illumination, but it does show on fast moving objects. Not something you'd want to work under for a long time.
I'll guess the name "mine light" implies it being a waterproof and potentially explosion proof light, but the availability on eBay voids all serious industrial use.
Two sizes are available with multiple usage variations. A large 300W unit and a smaller 100W unit. Both have hexagonal cases that can be joined together in a honeycomb grid. The mounting options are a wall bracket, street light pole bracket and chain suspension.
You may find them if you search for 300W LED street light.
The power rating is so high that you can feel the heat radiated with the light. They can be doobied to reduce the power by putting a capacitor in series. The capacitor will need a parallel discharge resistor for safety. Running these at full power will probably yield low lifespan, as the LEDs are being run quite hot.
Visually, these lights are quite stylish and appealing, but will not be suitable for use as video lights. Their ideal location might be an outdoor barn or yard.
I specifically avoid using intrusive mid-run video adverts.
