Our refurbished lights are completely refurbished. We disassemble the light and check for any suspect parts. Those parts are replaced with new parts. All refurbished lights have new sockets, lens covers and light bulbs. The lights are then painted with automotive, acrylic enamel paint for a hard, durable finish. We install too if you are in our local area. We have lights available from leading dental industry manufacturers like A-dec, Marus, Pelton & Crane.
