Miniature light bulbs add a classic look to Christmas trees and decorations. They are those thousand points of light (either white mini light or multi-color miniature Christmas tree lights) you remember being in awe of as a child. Miniature lighting comes in a variety of colors of mini bulbs, and light cords vary from white to green for specific decorating needs. Not all Christmas lights are the same. Mini lighting quality varies by gauge of wire, quality of construction and the like. Not all sets stay lit if one bulb is loose or burns out, or can be plugged in end-to-end with another set of mini lights. When you check price, be sure to check quality too. Commercial quality light sets might be preferable for some commercial grade applications.
