    Had no box previously, and want to have 2 10lbs lights instead of 1 bar.

    Old wire would reach one, and will run new wire to the other thru studs.

    What kind of boxes can I use? Thinking round, but will be tight next to
    a drain line, so it is possible to use a rectangular box? Plastic or metal?

Boxes used at luminaire or lampholder outlets in a wall shall be designed for the purpose and shall be marked on the interior to indicate the maximum weight of the luminaire that is permitted to be supported by the box in the wall, if other than 23 kg (50 lb). At every outlet used exclusively for lighting, the box shall be designed or installed so that a luminaire may be attached.

    Exception: A wall-mounted luminaire weighing not more than 3 kg (6 lb) shall be permitted to be supported on other boxes or plaster rings that are secured to other boxes, provided the luminaire or its supporting yoke is secured to the box with no fewer than two No. 6 or larger screws.
