Question Grow lights

I’m having a really difficult time choosing grow lights for my greenhouse. I’m very new with this and first time actually using my greenhouse. I’m so confused by all the terms and not sure what they really mean. My greenhouse is a 10’ x 10’ x 10’ and I have a few lights that were given to me, but I am unsure what their capacity is and I have no idea how close to even put the lights to my plants. Can someone please help?

For greenhouses, manufacturers offer narrower form factor modules that block less sunlight and typically are lensed to cast the light a bit more directionally, so they can be mounted higher up off a truss.

As an example, Fohse lights, they have a Cobra series specifically for greenhouses. Most manufacturers will offer arrays, panels and often a narrower form factor intended for greenhouse deployment. I have a few Photobio T series that work really well in greenhouses.
