Having Christmas lights on throughout the holiday season without incurring hefty power bills is achievable with solar Christmas lights, as tapping solar energy is free.

These lights work without an extension, making their outdoor and indoor use limitless. They are connected to a solar panel that uses sunlight to charge the battery during the day. The stored solar energy is used at night when the lights are on.

The World Bank agrees with renewable resource experts that the lights are environmentally friendly and economical during the holidays. They are also safe for indoors and outdoors. Queensland Government Electrical safety agrees that one of the safety tips to ensure that your Christmas does not go into disaster is to use solar Christmas lights.

Some things to consider when buying Christmas lights include how long they take to charge, the lighting modes they offer, their working hours, and, most importantly, the IP rating.

It took us one week to test 50 solar Christmas lights. We used a darkroom to test the lights to determine the brightness of each product. We also checked these lights’ advantages, disadvantages, effectiveness, and efficiency. Below are the findings of the tests.

Best for longevity: Dazzle Bright 2-Pack Solar String lights

Dazzle Bright 2-Pack Solar String lights / Dazzle




What we liked:

They are very colorful and bright.
Flexible to use outside and inside the house.
The wiring is good and blends with the background.

What we didn’t like:

The bulbs used are hard to replace when they break.

The Dazzle Bright String lights topped our list since their batteries last longer than other solar Christmas lights in their category. For most lights, the standard running time is 8-10 hours. However, the Dazzle Bright String lights give you 12-14 hours. But, you must charge them fully to ensure they give you the maximum running hours.

These lights’ wires are less noticeable, which makes the bulbs more attractive. The light controls are also at the back of the solar panel and are less noticeable. These controls are used when switching into different light modes such as flashing, steady on, waving, combination, slogs, slow fade, sequential, and twinkle. Additionally, the copper wires are anti-rust and can be used outside and withstand all kinds of weather.

The Dazzle lights come with 2 LEDs and 120 bulbs. However, the bulbs are irreplaceable since spare bulbs are unavailable.

Number of bulbs: 120| Length: 46 feet | Working time: 10 to 14 hours | Color: multicolor| IP rating: IP44|

Their working hours are 12 hours after charging them fully for almost 6 hours in sunlight. Having an IP65 rating, they can withstand harsh weather conditions. We confidently used them outdoors on rainy and snowy days.

On Amazon, these solar Christmas lights are among the cheapest, which makes them best sellers on the online store.

They automatically turn on at night and off when the sunlight appears and are chargeable only when turned off. They have a built-in battery, which is a disadvantage since it can wear off or get faulty and is irreplaceable.

These solar Christmas lights have eight different lighting modes and a control switch button that operates these different light modes. They have two LEDs, each containing 200 lights with different colors, making them attractive.

It has a replaceable battery.

What we didn’t like:

The wire is dark green and highly noticeable.

With an IP rating of 65, these lights can be outdoors throughout the season and withstand snow storms. Additionally, their solar panels have stakes to keep them firm on the ground during wind gushes.

They have 200 LED bulbs on 72- feet strings that make them easy to wrap around fences and trees. The length between the LED lights and the solar panel is 6 feet, which means that the solar panel can be kept away from the lights to avoid interfering with the glamour of the lights. However, the copper wires are too conspicuous since they are dark green and do not blend with the background.

Depending on the buyer’s choice, these lights can be purchased in one solid color or multi-colored.

We noted they have a memory chip to record the last mode set. This makes it easy for the users since they do not have to reset the modes every time they turn them on. They also have night sensors that turn the lights on at night and off when at sunrise.

These lights have four brightness levels, including a dimmable level, which is highly convenient for indoor decoration. They are also super long and can be used when decorating a Christmas tree indoors or on the walls.

These Christmas lights have a low voltage of 29V, which makes them safe. When testing, we discovered that the low voltage reduced their power consumption. Moreover, they have an IP rating of 44, making them waterproof.

The lights have a timer setting where the user can set the number of hours they stay on. The timer is between 6 hours to 18 hours. They also have 8 lighting modes that users switch, according to their desire.

The lights are controlled using a remote control that makes it easy to maneuver the functionality of the lights. However, for the remote to work efficiently, you must point it directly to the receiver.

Each string has 200 bulbs and a length of 72 feet. They also have a 6-feet distance between the solar panels and the first bulbs, which makes it easy to charge at any sun-lathering spot.
