I needed an affordable ceiling lamp, and I liked the look of the GRONO frosted square table lamps – they are about 4″ square by 10″ tall. They came with a small size socket and low watt bulb with a roller plug on the cord – el cheapo style. I think they cost about $5 or $6 each. For about $3 I got a plug with a standard size socket and replaced the original plug and socket. I cut off the plug end and hard-wired it to the house current. I made small square bases with a little lip out of Baltic birch plywood, and wall-ah! Ceiling lamp! This was in 2007. I don’t know if they still sell these lamps.
