BLURPLE example : from some years back .
Vipar " 600 " ( more like 287 at wall ) but since my plants loved this panel and I grow only for myself , it did very well . I HAD to supplement more CALMAG with my girls more than other lights BUT it worked out good. I have moved on to Quantums
But still use the Vipar. I am not familiar with Mezihi , but KNOW that there are growers on this site that use them and post grow journals .... Lurk the forum for them and see what they are doing.

MARS
MARS is straight garbage ... Although I " started " early with these paperweight panels ( white classic panels / pink light ) it was a dog. It did grow bud but was not reliable - rows of LEDs would go south. But it grew weed .... I even was offered to test a Reflector Series once but passed. My old T5s seemed to work better.

HPS
Hated my HID batwing setup - buying bulbs , pizza oven temps , high power use.
Swapped to a cool tube , better temps but hated getting low bulb life. I grow perpetual so I needed something with longer life.
Quantum
Currently using these ... Does the trick . But those old blurples just made me a better grower so it wasn't a bad thing after all. You will move on to bigger better things , we all have. But will never get rid of my Vipar ..... Just sayin. Lol.
