Electrical Help

In the process of replacing old recessed canned lighting with new LED lights. I have removed the old can to gain access to the old junction box. Everything is in order. Grounded wires and white / black coming out to power the old light.

Now, new LED lights going in, new (2nd) junction box going in. Question is (please excuse me I know shit about wiring that's why I'm here, don't want to burn our house to the ground) do I need to use the ground in the new junction box as well? I'm not omitting the old box because it's good to go. The way I see it the wires are already grounded out of the old box, attach Black / White wires to new led light and I'm good to go. Shit prior install/Exposed wires should still trip the panel?

why install a 2nd junction box? You could just go straight from new lights to the house wires in the original junction box. Someone correct me if I'm wrong - I'm no electrician.

I have 6 recessed lights that are daisy chained, should have mentioned that. Kinda a PITA to rewire all that. Also, the new junction box has a switch to adjust the temperature kelvin.

I can almost assure you the answer is, to keep from burning your house down, no. To meet code, yes. I'm not an electrician, nor did I stay in a Holiday Inn last night, but I have a brother-in-law with a master's in electrical engineering and a brother retired from the IBEW.

I'm not a professional electrician, but an educated novice and do all my own home wiring (garage subpanel, 240v service for welder, two switched lights, etc.). Always ground when possible. It's just safer. The armor clad (AC) cable in your picture provides grounding through the armor versus a bare copper wire. If you're not using AC cable to connect the lighting to the junction box(es), then use NM-B aka Romex which has a ground wire.

The Home Depot Electrical 1-2-3 book is an easy to follow resource if they still sell those.

Then another box makes sense. Just ground it out, like mentioned elsewhere here. Grounding is good. Easy too.
