The mars doesn't compete with the HLG or other LEDs of that level of efficiency.
The lumatek is a great light, its UK made(so no import duty), has a good warranty from a well established company and can be bought from many UK hydro shops or diyleduk.
Its also square so will get better light uniformity in a square tent than an rectangle light would
Would the lumatek attis 300w be too much for my tent?
