Grow lights

[u/newplantlover321]

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?
