I don't think this was ever used. Just opened box item. This bell-shaped LED bulb with a visible filament spreads a warm glow through the brown-colored glass and adds a decorative detail to your interior design. LED light bulbs are both energy efficient and long-lasting, with a lifetime of approximately 15,000 hours ? two benefits that allow you to save money on both bulb replacements and electricity. This LED light bulb spreads the same warm light as a traditional light bulb without flickering or emitting any sound. Just what you need to create a nice, cozy atmosphere in the room. The color rendering index (CRI) of a light bulb defines how well the light reflects true colors. A value above 80 is good and close to a natural light.
