Installing ceiling light box between 2 joists
How do I install a new junction box between 2 joists in the ceiling?

You are going to need to supply more information. Is the ceiling open or drywalled? If drywalled how do you know where the cable is? Why do you need to splice?

Existing cable.
It's an open ceiling now as I removed everything to redo it.
New ceiling will be 2 layers drywall for soundproofing then wood planks.

Nail a junction box onto each joist run a cable between. Staple to each joist within 8". The box must remaining permanently accessible.

Do you have enough cable to make all the connections in the single box? We were thinking "junction" box, not light ceiling box. If you don't have enough cable, you will need to use two boxes, and extedd from one of them to your light ceiling box.

Yep plenty of cable... it's just one light.
There was plywood between the 2 joists before and a light box hole cut in the middle but I thought I had seen light boxes supported just by small wood pieces or metal extensions?

As I have 2 layers of drywall and 1 layer of planks = 2 1/4", what's the best way to extend the junction box downwards to be level with the planks?

Use a bar box like Ray posted but use a metal box with a 4" box extension ring.
