More people are choosing LED candles over traditional wax candles, especially for decorations. There are some main strengths for LED candles:
1. Safety – LED candles eliminate the risk of an open flame, making them safer to use around children, pets, and in environments where an open flame could be hazardous. 
2. Convenience – LED candles provide instant illumination without the need to light a wick. They can be on/off easily, especially for the remote controlled ones. 

3. Longevity – LED candles last significantly longer than wax candles, providing hundreds or thousands of hours of use from just battery power. 
4. Eco-friendly – Being battery-powered, LED candles are much more energy efficient and environment friendly than traditional wax candles. 

5. Versatility – LED candles come in a wide variety of colors, sizes, and shapes to suit any decor need. And many of them are designed to realistically mimic the flickering of a real flame.
6. Allergy-Friendly – LED candles produce no smoke, soot or scents that could trigger allergies or asthma like some wax candles. They’re also easy to main, no need wick trimming, melted wax cleaning, etc.

While wax candles provide a traditional ambiance, LED candles offer significant advantages in terms of safety, convenience, longevity, energy efficiency and low maintenance that are making them an increasingly popular choice for home decor and events.
