Silicone dipped bulbs are designed for ambiance and not for where a lot of light is required. However, in a situation where ambiance is required, they add a dramatic effect when combined with our candle covers. Our 6 watt silicone dipped bulbs are hand-dipped to produce a candle flame appearance. When illuminated, light travels all through the bulb and into the flexible tip. These bulbs are incandescent, not LED. They are fully dimmable and do not require a special dimmer.
