A more logical way of analyzing it.
Look at the actual data it tells you.
So its a 800watt light, and it has an efficiency of 150lm/watt.
The problem is the form factor. It has a single point of light and it says its 120degrees.
basic algebra tells me that means the other two angles of that 120degrees triangle are 30. So if you hang this thing the light will come out like this.
So that green line is how high you have to hang it to cover an area. See the problem? Not very practical for what you want to use it for.
Then throw in that you have all the heat that 800w light at 150lm/watt will produce all being at a single point. Even more impractical.
Some of that style of light can be good for growing, a "ufo" style light they call them but the details are completely different where the beam angle isnt for lighting a warehouse at a high height.
The growing ufo ones have a beam angle much smaller and each "ufo" is smaller watts and covers more like a 2x2 area so 4 are hung in a 4x4 tent. A more common light for growing is the cob syle growing light and before smaller diodes in panels became the efficiecy kings most led growers grew with cobs.
Things like https://www.amazon.ca/Rapid-CXB3590-Light-Fixture-3000K/dp/B07BN4RVC3
are cob lights and grow amazingly and what many ppl used up until like 2016 they were the best you could get for LED.
This light is a definite no, but some ppl grow fantastically with this style, its all about the details.

Yes just need a eu to uk power adaptor. But if it's just no good I will forget. Just found them on ebay and wondered if I could make use of them.

you wont get 220v from a 120v output thats if you live in the states, or are you uk?
13amp plug is ok up to 3000w.
