1. This is an special size decorative vintage led opal glass bulb, the bottle shaped glass is with white opal color, inside the opal glass globe, there is 4 pieces of 68mm length sapphire substrate filament led, totally 5W and 420lm light output. For a clear glass bulb, the lumen output should be about 10-15% higher, because opal glass is not clear, it stopped some of the light from coming out of the opal glass.
2. We Dongguan Bofa lighting company are doing a lot of opal glass bulbs, our manufacturing process for opal glass bulbs is very mature, the opal color is much even, there is no opal color stripe, no spots, no light leak spot. The light output is also much even, no dark area, always same color. No matter for small or large big size opal glass bulbs, we can control a very good opal color quality!
3. Opal color is made by opal color oil coating, there is inside opal color coating and outside opal color coating. For small size bulbs, such as C35, A19, ST64, G125, usually it is inside opal coating. Because the opal color is inside of the glass globe, so the opal color looks like a mirror, and it is not easy to be dirty or scratched. However, for big size opal glass bulbs, the inside coating is not good, because the area is too big, the oil may flow which cause stripes and light leaking spots, also, because the big size glass bulb has a very big room inside, the spray gun has to move around inside, this will cause the coating not even. This is why large big size decorative led opal glass bulbs is outside opal coating. Also, outside coating is easy to control, and easy to work, we can see the coating status much clearly. However, because the coating is on the outside surface of the glass bulb, so it is easy to be dirty or scratched, so we have to take good care of the outside coating opal glass bulbs during production, for example, we use paper bag to pack the them after each section of production, and we have QC check the coating again, pick out the defects which is happed during production.
4. For some opal glass bulbs, the coating thickness is thin, so we can see the led filament when the opal glass globe is lighting on. Some opal glass bulbs has a thick white opal coating, when it is lighting on, we can not see the led filament, the bulb looks like a moon. Different customer has different preference. If the filament design is nice looking, for example spiral filament design and loops filament design, we can make the opal coating a little thinner, people can see the filament design when the opal glass bulbs is lighting on. For the simple filament design, I think the thick coating is better, the whole opal glass globes looks like a moon when it is lighting on, of course thick coating will reduce a little more light output.
5. People like opal glass bulbs, because the light output is much soft, and the opal glass bulbs is not dazzling when it is lighting on, it looks like a moon, or glow ball, so it can be used as a sign hanging on the window.
