Yes, you must use an extension cord specifically rated for outdoor use to power outdoor lights, such as Christmas lights. Extension cords intended for indoor use lack the protective properties to withstand exposure to outdoor elements. To safely hang and power lights outside your house or in your yard, always connect them to an outdoor power source using an outdoor-rated extension cord.

How many string lights can be on one outlet depends on a number of varying factors, including the total wattage of your circuit, the type of lights, the energy needs of the lights, and cord specifications. It’s better to play it safe here to protect your circuit, so figure out the max wattage of your circuit, compare that to the lights, and move on from there. Generally speaking, LED string lights require less energy than incandescent bulbs, translating to a higher number of lights per circuit. 

If you only need strands in safe and easy-to-reach locations and are sure of your electrical system, you can probably purchase and install lights yourself. To do this, carefully test your outlets to ensure there aren’t any sparks or other concerning issues. Your budget might also influence this decision, as going the DIY route can be significantly cheaper.

Technically, you can use duct tape to hang Christmas lights, but it’s not the best bet. Duct tape or other types of tape retain moisture, which isn’t ideal when near an electrical wire. Plus, it can peel off due to the elements. Duct tape is also a very unattractive option, visually speaking. Instead, opt for roof clips for Christmas lights, which are affordable and easy to use.
