if you dont mind spending a little extra I would do some research on what best
https://horticulturelightinggroup.com/collections/kits fixture from here works.
If you dont feel like you can watch a video on how to strip a few wires and screw a couple screws in you'll have no problem setting one up. Theres a video on there on how to set them up. What size grow chamber?
If you need it to have government ratings on it you have to buy a whole fixture which costs a lot more
If you really wanna save some money you can look into passive cooling with no heatsync. I got the heatsync because I like the idea of having less stuff hanging in my chamber
If you wanna go the QB by HLG route, I'd send that mars right back to where u got it
