- This is a bomb shape extra big size dark grey color flexible soft led light bulb, dark grey color bomb, very special led decorative lamp. It is really a nice lighting decorative lamp for using in dining room, restaurant, coffee bar. Because bomb shape dark grey color decorative lamp is really attractive!
- Only 2 watts and 150lm output, 2200K color temperature, with the dark grey color glass, this bomb shape lighting decorative led bulb is much nice looking, a lot people like it. Except dark grey color, there are also gold color glass, clear color glass, semi-black color glass.
- For decorative led lamp, there are only two kinds of color temperature, one is 22000K, the other one is 2700K. For 2200K, the real color temperature range is 1800-2200K, mostly it is 2200K +/-200K, 1800-2200K is amber soft warm light, that is why most people like 1800-2200K. The CRI(Color rating index) is more than 90 in the color temperature range of 1800-2400K, the lumen output usually is about 30-50lm/W. 2700K is a little more bright than 2200K, but it still belongs to warm light, the tolerance for 2700K is +/-200K, so the range is 2500-2900K. However, we can control it within 2500-2700K. The CRI for 2700K is more than 80, less than 90, its Ra is lower than 2200K. However, the lumen output of 2700K is more than 2200K, it is about 50-70lm/W at 2500-2900K. So if the led is same, the CRI is always contradicted with lumen, when CRI is high, lumen is low; when CRI is low, lumen is high. Because Led light is not real light like incandescent bulb, it is a complex light which is reflecting from fluorescent powder.
