Hey folks I have been looking into growing for some time.. I ran into a bunch of led lights that I got for free from my job. Anyways I know there decent because they come in carrying cases..they say sales sample only ...upon opening to check them out I found only one piece of Information .In total there are 5 lights four are the same and one is larger the brand is Orion and the paper says the small ones are Orion Apollo high bays HBAC2 and the bigger one I don't know..I am trying to figure out how to test to see if they even work. The biggest issue having is figuring out how to install a wire to them . I have electrical experience but they have like a pin plug ..the questions I am needing answers to are. 1. Are these lights good for growing. 2. How do i test these lights. 3 what's the value of these lights 4. Since there sale samples do they work and finally how much room would these cover......I have included photos
