1. Pillar shape, long tube decorative filament vintage led bulbs. 6W 2200K 400LM output, amber warm light. The idea of this design is from the shape of the television tower, actually it is a tubular shape, tube vintage led bulbs.
2. We bofa lighting company only use the highest quality led filament for each of our decorative vintage led bulbs, it is sapphire substrate, Epistar 3050 big size Led chips, Gold wire connection. High quality led filament has a higher lumen output, higher CRI, longer lifespan, and efficient heat sinking.
3. Because most of the decorative led light bulb is with extra big size or huge large size, so the glass bulb is more easy to break, including the glass stem in the center of the led bulbs. Also, because the led filament is much heaver than incandescent filament, the glass stem has to burden a lot more than before, so we Bofa lighting company enhanced the glass stem. We made the glass stem thicker, the normal stem was about 3.6mm diameter, now we increased the diameter to 6.9mm, with hardness material glass. The glass stem is a tube, not a solid glass rod, glass tube is better than glass rod, because solid glass is easier to break with heating than glass tube. In order to make the glass stem stronger, we also put a hot-shrinking plastic tube to the outside of the glass tube stem, then we hot it, and the plastic hot-shrinking tube is combined together with the glass stem tube, by this way, the glass stem is much more stronger.
