Lets just have a look at the specifications
Specifications:
Dimensions: 52 Inch
LED Count: 390/PCS
Operating Voltage: DC 10-30V
Color Temperature: 6000K
Power: 3900W
Lumens: 390000LM
Beam: Combo Beam
Waterproof rate: IP 68
3,900 watts is wrong . have inserted comma for clarity
390,000LM is wrong. have inserted comma for clarity
Elsewhere it declares light output as 31,200LM, 12 volt and it a FOG light with a combo pattern.
Now top end specification LED are capable of 100+LM measured output per watt.
Top end spec LED comes with top end price tag of $+ each rather then cents price each of bottom end. Note no mention of LED maker or product number, will not go down BIN route (Batch Identification Number often split into10 different grades within a particular product code)
Now is claimed light output of 31,200 or is it 390,000 LM the theoretical light output, the calculated light output or a measured light output?
My guess? Wet a finger, stick it up in the air, guess a number and stick a nought or two on the end.
As for the IP rating, shear guess work

Yes it might slip under the radar. However am still arguing with an importer about a duty/vat of £90.25 invoice on goods and shipping costing 165 USD 3 months down the line. Of course there is the handling charges etc on top
