Pot Lights for Insulated Ceilings

Have 4 brand new and 6 excellent condition used pot light boxes available for insulated ceilings. $10 each as a whole lot, or $15 for the new ones and $10 for the used ones. I also have brand new retrofit pot lights available (around 8 new in box and around 6 used ones). They are in excellent condition and are $45 each new without trim or bulbs. If you want bulbs as well, I have brand new Halogen PAR 20 bulbs with gimbal trim rings available. I also have LED PAR 20 and LED PAR 16 bulbs and gimbal type (swivel) trim rings. These are the best type of lights because if a bulb ever burns out, you can replace it temporarily with any type of regular screw-in bulb. New made-in-China pot lights cannot replace just the bulb; you need to hire an electrician and replace the whole unit, driver and all.
