I found the manufacturer of this lamp and here are the details: https://szsaidi.en.alibaba.com/product/62075837454-806203303/1200W_LED_Grow_Light_Full_Spectrum_Grow_light_with_UV_IR_for_Greenhouse_Hydroponic_Indoor_Plants_Veg_and_Flower.html?spm=a2700.icbuShop.41413.20.246631a00UB9Wa
True power is 500W so it might be powerful enough. I'm not sure about the quality of the leds and the amount of heat that his thing produces. This lamp is old tech so you might experience some heat problems but if you have good ventilation there should not be nothing to worry about. I had old 315W led in my tent with 200W from COB leds and I was struggling with the heat 'cos it was almost 30C.
