Question: Are the bulbs true to color?

Answer:  Our C9 Diamond Facets Twinkle lights are 120 volts. 

Question: What is the wattage of these bulbs? 

Answer:  Our C9 Diamond Faceted Twinkle bulbs are .8 watt bulbs. 

Question: Can I use these in an existing strand I already have with incandescent bulbs? 

Answer: You can use an existing stringer you already have; you just would need to confirm the base sizes are the same and that you either have all LED bulbs on the strand or all incandescent. If you combine incandescent with LED you lessen the life of the LED bulb because you are feeding it with more energy than it needs. An incandescent bulb needs 5 watts of power to work the LED needs less than a watt to shine. 

Question: What kind of stringer do I use with these bulbs? 

Answer:  These bulbs have an E17 base. Please see our assortment of C9 stringers available to purchase.
