Question: Can these be used in a string I already own? 

Answer:   90% of the time this will work. There are 2 points of contact the bulb needs to work; one on the bottom and one on the side. Most of the time our bulbs will work in other strings, so yes I would try it and if they do not work then you may need to replace the string or try a different brand bulb. You will also need to make sure the string can handle a 7 watt bulb in each socket.

 Question: How many can I string together? 

Answer:  This particular product is just replacement bulbs. Our strings are sold seperatly. These can be made with green, white, brown or black wire. 

Question: What kind of stringer do these lights work on? 

AnswerThe C9 bulbs will work with a stringer that has an E17 base. The strings come in green, white, brown or black.

Question: Why is the color of the bulb not the exact color as pictured?

AnswerLighting and background can affect the picture, ie coloring. If you have any questions about the color of the bulb please reach out to customer service to receive more information. 

Question: Will the color of the bulb be a true red, blue, green, etc.

Answer: The Incandescent bulbs have a white light inside and the bulb is dipped in color.  Because the light inside is white the color on the outside is muted. If you want a true color please take a look at the LED bulbs, these have a colored light inside as well as the bulb having the same color.

Question: Will the “Black Light” C9 bulb make things glow? 

Answer:  Even though the name of this bulb is “black light” it does not have the UV properties in it as a normal black light does.
