Description

Features:
1. This is a standard vintage G45/S14 globe crown gold light bulbs, there is 4pcs 38mm filament led inside the gold crown globe, under the gold crown area. 4pcs 38mm filament led is 3W rated, can reach 4W at maximum. This crown gold color is a little more fresh yellow, we also call it deep gold color. Because different people has different preference, the crown gold color is made by electroplating, different production has a little different color, that is why crown gold color has several different color versions. However, if customer has one color requirement, the crown gold color is always same among different production batches.
2. Crown gold light bulbs has 2 colors for the crown part, outside is gold color, inside is silver color. Gold color is for crown gold, silver color is for reflecting. When we crown gold light bulbs, we make silver coating first, and then make one layer of gold coating over the outside of the silver coating, so it is two times electroplating process.
3. For all reflecting bulbs, including crown gold light bulbs and silver crown mirror globes, the filament should not be out of the crown area, otherwise the reflecting of the light is not good. That is why most of the cap reflecting bulbs has the filament led same level as the reflecting part, and hide most of the led filament inside the cap reflecting area. However, for this small size G45/S14 crown gold light bulbs, if the gold crown coating area covers all the led filament, then the coating area is too much, almost reaches to lamp cap, so usually for small size gold crown medium base bulb, some part of the led filament is outside of the coating area.
