HOW MANY LIGHTS DO I NEED FOR MY TREE*?
Our Christmas Light Calculator™ is designed for both residential and commercial Christmas trees and lights. It is based on standard 6" LED mini light spacing or 12" LED C7/C9 light spacing.

The recommended feet of light string from our Christmas Light Calculator™ is based on what our average customer has felt is a perfect number of lights for their tree. Keep in mind that the result is not for the number of lights, but for the number of feet of light string you should use. This is based on light strings where mini lights are spaced at 6 inches apart, or C7 lights are spaced at 12 inches apart. For mini lights the actual number of bulbs will be 2x the recommended feet of light string, and the for C7 lights the actual number of bulbs will be the same as the recommended feet of light string.
If your light strings have different spacing, 4 inches between mini lights for example, then you can simply use the number of bulbs instead of the number of feet of light string. To get the number of bulbs for mini lights simply multiply the result of our calculator by 2, and for C7 lights the recommended number of bulbs will be the same as the result you see.
If you tend to like less lights on your Christmas tree than most people, you can change the recommended number from our calculator. For example, if you think you prefer only 50% of the lights that most people use, you can multiply the result of our calculator by .5. If you think you prefer to have 80% of the lights that most people use, you can multiply the result by .8.
If you know you like more lights than most people use on their Christmas tree, you can also add to our recommended number. If you want 50% more lights than most people use, then you can multiply the result of our calculator by 1.5. If you want double the number of lights that most people use, then you can multiply the result by 2.
If you have any questions or are still uncertain please feel free to send us an email or give us a call. We're happy to help!
Christmas Light Energy Calculators
*Please consult a licensed electrician before you begin any lighting projects. You can find out how many amps your circuit(s) are rated for by looking at the number on your circuit breaker. Most circuits are rated for either 15 or 20 amps. The above calculator assumes 80% of the total capacity for safety. It is also important to know how many outlets are on one circuit. You can determine this by making note of which outlets stop functioning when you switch a circuit off.
*The packaging your lights came in should have either the total watts of the string or the number of bulbs and watts per bulb.
*This tool provides you with the maximum number of light strings you should put on one circuit. It does not tell you how many light strings you can connect together. Generally you should not connect more than three 50' incandescent strings end to end. You can connect a larger number of LED Christmas lights together since they use 90% less power. Please see the packaging on your LED lights for more information.
*The number of watts per bulb should be found on the packaging your lights came in.
*Be sure your light strings and extension cords are rated for sufficient amperage.
