1. This decorative led opal glass globe bulb has a large size which is diameter180mm and 190mm length, from the size we can see it is not a normal globe, it is a oval shape globe, diameter is a little longer than the total length. Inside this oval shape opal glass bulb, there is 6pcs 68mm length led filament, one piece of 68mm led filament is 1W rated, so totally 6W.
2. This large size decorative led opal glass globe has 450lm light output at 2700K 6W. For most of the decorative vintage Edison led bulbs, the color temperature is 2200K and 2700K. For Led opal glass bulbs and Frosted glass led bulbs, usually the color temperature is 2700K; For Clear and Amber vintage Edison led bulbs, the color temperature usually is 2200K. Different color temperature has different lumen output, it is about 100lm/W for 2700K, 80lm/W for 2200K. Also, different color temperature has different color rendering index(Ra), CRI is between 80-90 for 2700K, CRI is between 90-97 for 2200K. So 2700K high color temperature has a high lumen output but low color rendering index; 2200K low color temperature has a low lumen output but has a high color rendering index.
