LED vs. Incandescent Holiday Lights

Thinking about LED vs. incandescent for your holiday display? LEDs are more energy-efficient, longer-lasting, safer, and brighter—ideal for large San Antonio setups. SA Holiday Lighting can design, install, and maintain your lights for a stunning, worry-free season.

With the holidays coming up, you’re probably wondering whether to go with incandescent or LED lights. It is essential to understand the pros and cons of each lighting type available to us. We have to look at both the initial cost of the lights and the overall energy costs to keep them up all season long. For real-world examples and pricing, explore our Seasonal Lighting Packages or compare longer-term options under Permanent Lighting.

Here are five reasons why LED lights are better than incandescent lights.

Energy Efficiency

LED bulbs use less electricity than traditional incandescent Christmas lights, making them the energy-efficient option. In reality, incandescent or regular lights are being phased out entirely due to their inefficiency, making them harder to find (Source). The greenhouse gases emitted by incandescent bulbs may have an environmental impact. LED bulbs emit fewer greenhouse gases than incandescent light bulbs, making them not only more effective but also more environmentally friendly (Source).

LED bulbs consume less power to operate, allowing you to use less power for the same number of lights as conventional series lights. This can save you around 80 percent on your electrical bill this year compared to the traditional Christmas lights (Source). Reduced power consumption is an advantage for people who prefer to really light up their house with many lights (Source).

Durability Between Incandescent & LED Bulbs

From a durability standpoint, it follows that you’ll receive 50 times the sum of use from a series of LED lights compared to a series of incandescent lamps (Source). Therefore, while LED lights are more expensive to buy than incandescent lights, you save on the life of the bulbs and on power expenses.

LED bulbs are less likely to short out than standard bulbs, so you’ll spend less time replacing them. See how we handle in-season support and labeling on our Seasonal Packages page.

Installation Pros & Cons

Because of their low wattage, you can connect many more LED strings so that you will need fewer extension cords and fewer power outlets. This will make installing LED lights easier. For complex layouts (trees, peaks, long runs), start a quick plan here: Get Started.

Brightness

With technological development, LEDs are the same or even brighter.

A few years back, LED lights were dimmer than incandescent lights, leading people to stick with traditional string lights. It has changed, however, and the two bulbs put out a similar quantity of light. Browse recent LED results in our Project Gallery.

LED lights stay cool even after prolonged use.

After hours of use, incandescent lights can become scorching to the touch (Source). This means making sure you turn off the lights to avoid hazards. LED lighting gives a safer option and peace of mind. Learn about our safety-first approach and insured crews on Get Started.
