FAQ

What Christmas lights do the professionals use?

According to our research, one thing to look for specifically when shopping for professional Christmas lights is “commercial-grade” labeling. This suggests these lights are used on a professional level. That said, if you want to get more specific, the two most popular lighting sizes for professional usage are C7 and C9, which accompany E12 and E17 lighting strings, respectively.

Which Christmas lights are bright?

Traditional Christmas lights relied on incandescent filaments to light up, which are warm but not particularly bright. These days, LED lights—which are much more common—are cooler but far more bright and energy efficient. LED lights also often come with the option to customize the colors, making them far more versatile than traditional filament lights, as well.

How do I make my Christmas lights look like a pro?

Getting quality, long-lasting Christmas lights is the first step to making your display look professional. However, another factor is how you arrange them. Making a plan ahead of time for a cohesive, well-thought-out display (and not cutting corners) will go a long way toward making your Christmas lights look more professional. There are a lot of online tutorials for this, as well, if you want some additional help.
