From the board marking in the center:
Power: 200W
Voltage: Around 30V DC
Current: 1500 mA max
This means the light likely uses an external LED driver that converts AC mains power to the required DC voltage/current.
The panel contains many small SMD LEDs arranged in circular rows.
These are typically SMD 2835 or 3030 LEDs.
Such configuration helps produce high brightness with uniform light distribution.
Typical performance for a 200W high bay LED:
Lumens: ~24,000 30,000 lumens
Efficiency: 120150 lm/W
Color Temperature: usually 5000K6500K (cool white)
