Our 5W light bulbs are an incandescent lighting. Each bulb having a candelabra base also known as a C7 base and each bulb dipped in a silicone color coating, with the exception of the "Clear" silicone bulb. Each light bulb has its own unique characteristics, some have a long tip and others a shorter tip, some have a texture and others do not. We hand dip each of the light bulbs individually, no machines here! Rather than having a harsh white light emit from the bulb this silicone color coating allows a soft light to glow, creating a soothing ambiance to any room!
