Colshine is the first and original manufacturer of top quality vintage porcelain lamp holder,porcelain wall lights,waterproof ceramic sauna lamps,porcelain ceiling roses and retro ceramic light swithes, etc, in white, black, brown and others for option. Since 10years before, Colshine start to make these products to Europe for Zangra and other customers; at the beginning,it's always a headache to make black color, because nobody has experience to make black color shiny and smooth, even it's hard to get the black glazing material(no body make ceramic lamp holder and porcelain wall lights in such colour before, there wasn't demand).

We can distinguish the quality of porcelain lamp holder and porcelain wall lights like this:

1. Color/glazing

Such as white color:  if the color is not shiny enough and smooth, but with some black spots on body, or there are some place lack of glazing, then it's not good.

If it's blak color, it must be dark black and shiny. If the temperature was not control well during production in tunnel oven, the final product is not black enough,sometime looks like dark red inside.

Further more, all the porcelain body must be full of glazing,it could not lack of glazing in the part for fixing lamp bulb or any other place(the edge).

2.Certer contacts and terminals

We use good quality phosphor copper as good conductor of power/electricity; the other copy cats use brass with copper plating only to save cost and offer lower price.

Further more, these must be a spring under the center contact L, it's important to have a spring here to make sure the center contact can touch the lamp bulb well, otherwise the lamp bulb would not working. But the other companies offer the copy without spring.

3.M10 thread

About the porcelain pendant lamp holder, these is an aluminum M10 thread on top, it must be fixed firmly, no rockable.

4. Without crackle or damage on porcelain body
