Most of the low cost home lighting in most countries is manufactured in China. Often it is of poor quality and may break into pieces while installing it. You may get better prices buying online on sites like eBay, but no warranty may be offered

Some popular suppliers of home lighting and related products are:
Home Depot – inexpensive with a large variety of lighting
Lowe’s – have many different types of home lighting products
Target for table and floor lamps
Ikea
