1. Large size amber gold glass copper wire led bulbs. Inside the amber glass globe, there are more than 50pcs Led chips, which is welded on the copper wire, the led chip is very small, not emits much light. The distance between led chips on the copper wire is about 5-10cm, it depends on production requirement. The color temperature for copper wire led light bulb is about 2200-2500K.
2. Copper wire led bulbs do not have much power and lumen output, usually it is about 1.5W, 90lumen output for 2400K. The color rendering index(Ra) is about 80-90. Because copper wire led lamps is not for illumination, it is for lighting decoration, so it do not have much high requirement for lumen, wattage and color rendering index. However, high CRI light is much more nice looking and comfortable.
3. Most of the color temperature for copper wire led bulbs is 2500K with amber gold color glass globes, and 2200K with clear glass globes. Both 2200K and 2500K are amber warm color light, the light of 2500K from amber gold glass globe is almost same soft than 2200K.
4. The copper wire led filament is put into the glass bulb randomly, when it is lighting on in the dark, the led chips emits a little light, looks like a lot of stars glowing in the dark sky, much beautiful. Our copper wire led bulbs has about 50-70pcs led chips, so the lumen output is high, about 80lumen for 2400K. However, there are some other company selling a copper wire led lamps with almost half quantity led chips, about 25-30pcs, in order to reduce the cost, so they can offer a much better price. For these cheap copper wire led lamps, when it is not lighting on, we can see almost the same quantity led chips as our copper wire led lamps, but half of the led chips is fake, they are not real led chips, only a part of transparent plastic, looks like led chips, on the copper wire led filament, there is one piece real led chip, one fake led chip, so half real, half fake. As a kind of decorative led bulbs, the copper wire led also need a high lumen output, so people can see it clearly, even from a little far distance.
5. For amber soft warm light, it is amber gold color, but some amber warm led light bulb emits a little green or blue light, people do not like this kind of color, but this green or blue color is only a little, we need to see it on the led bulb clearly when it is lighting on. There are mainly two reasons, one is led chip, the other one is glass bulb, details as below:
1>. Cheap or low quality led chip do not have a constant quality, usually low quality led chips gives little blue or green color, because the led chip is not fully covered by fluorescent powder silicon glue, which is yellow color(The led filament is yellow color).
2>. Generally speaking, there are about 3 colors for clear glass bulbs, they are white clear, green clear and blue clear, these three color is from glass material, they are all good quality glass, only the color is different. We Dongguan Bofa lighting company uses only white clear color glass bulbs for our copper wire led light bulbs, so our copper wire led bulbs are pure amber gold color output.
