How We Tested and Compared These Products

When testing the various brands of Christmas lighting fixtures on the market, there are several things we were looking for. First were the colors they were available in. At the very basic, we only reviewed products that had an array of colors to choose from to cater to the different tastes and preferences people might have when it comes to holiday decorations. Some of the color options they needed to have included warm white, cool white light, and multicolor variants.

Next, we were interested in their energy rating. They needed to be C9 LED light bulbs that guaranteed a 90% reduction in power consumption compared to traditional incandescent mini lights. To verify this, we used the touch test to check whether they remained cool after four hours of operation. If they did, they were definitely the energy-saving kind and, as such, made it to our shortlisted options.

We were also interested in the color quality. We only ranked bulbs that had a vivid and bright color display. Other features we also looked at include whether or not the lights in question were dimmable, whether they had vibration and shock resistance, and whether they were waterproof for outdoor use.

How to Choose the Best C9 LED Christmas Lights – Buying Guide


White lights on a Christmas tree

Before you go off and buy the first set of C9 LED Christmas lights you come across, we’ve put together a list of tips to keep in mind when choosing the best ones.


This is arguably the most important factor in any holiday display. Whether you’re putting up Christmas lights for your home or commercial premises, you need to pick the right color to create the perfect holiday ambiance.

While it is all a matter of preference, you can’t go wrong with red and green. These traditional Christmas colors are bound to infuse cheer and festivity into the season. Alternatively, you can go for an all-white Christmas and put up warm white C9 bulbs or cool white icicle lights.

Whatever you do, don’t mix and match color themes. If you put up multicolor lights, don't mix them with white lights. If you decide to go with an all-white Christmas theme, don't mix cool and warm colors. Pick one retrofit bulb color and stick with it.

Break Resistance

Next, you need to ensure the light bulbs you pick are shatterproof. You want to keep an eye out for Christmas lights made of acrylic resin, which offers a remarkable level of break resistance. If they fall to the ground, you don’t have to worry about having to clean up a shattered glass mess afterward.

Moreover, the acrylic resin also stays looking new even after several years of use. These bulbs don't fade, so the hues stay looking fresh, rich, and dazzling.


The other thing you need to think about is water resistance, especially if you’re looking for C9 outdoor Christmas lights. Each bulb's lens and LED diode should be in a single, sealed socket to prevent moisture from creeping in when it rains or snows.

Build Quality

Steer clear of cheap Christmas lights. As they say, if it's too good to be true, it probably is. A great way to ensure you're getting high-quality C9 bulbs is to only purchase them from reputable manufacturers. For safe indoor and outdoor use, brands like Echosari, Wintergreen, Brizled, and Hayata are CSA-approved and UL-certified. The last thing you need is to purchase a set of lights only to then end up with a fire hazard on your hands.

Dimming Feature

The other factor you need to consider is whether you can dim the C9 Christmas lights you purchase. That way, you can control the brightness level depending on the ambiance you're going for and whether you intend to put them up inside or outside your home.

Most of the Christmas lights with this feature offer four levels of brightness – 100%, 75%, 50%, and 25%. You can get a set of lights that come with a built-in memory function to automatically apply the last set level of brightness – even better. These lights don’t reset every time you switch them off, for instance, during the day when you don’t need them at maximum brightness.

Bulb Wattage

The bulb wattage rating on C9 LED Christmas lights defines the amount of energy required to generate a specific amount of light. Bulbs with a higher wattage glow brighter than those with a lower figure. Keep in mind that C9 LED bulbs, in general, reduce power consumption by more than 90% compared to incandescent mini lights with a similar wattage rating.


Is C9 the largest size of Christmas lights?

Yes, they are. C9 bulbs are mounted on E17 intermediate bases and produce a significantly brighter light than other C LED bulbs such as C7 lights or other smaller bulbs. They measure roughly 2.5 inches long with a 1.25-inch circumference, making them the largest traditional Christmas lights on the market.

Is a C9 bulb LED or incandescent?

Both options are available. You will come across C9 incandescent bulb sets and the newer C9 LED bulbs on the market. The main difference between them is their power consumption. Traditional incandescent mini lights use significantly more power than LEDs. Using C9 LED Christmas lights reduces power consumption by more than 90%.

How many LED C9 Christmas lights can I string together?

The answer to this depends on the electrical service they’re plugged into. As a rule of thumb, light strings should never exceed 85% of your breaker’s wattage. If you have a common household breaker, each plug shouldn’t exceed more than 1400 Watts. If you divide this figure by the wattage of each bulb, that will give you the total number of C9 LED Christmas lights you can string together.


There you have it – the best outdoor Christmas lights for 2022. Any of the bulbs we’ve reviewed in this guide would be an excellent choice for your holiday decorations. Go on – have fun with it.
