Depending on the time of day and the plan you are on, it costs us roughly 10 cents per KW (night-time is much lower on some plans). We pay around $4.38 per month for the increased security of leaving the lights on all the time, assuming 10 cents each light. It's not a terrible investment in personal safety.
The average household in the United States uses 15 percent of their monthly income on lighting bills. For those who can't afford to leave lights on all night, using low-cost options like LED lights or remote controls can reduce your energy consumption and therefore your bill. However, even with these options, most people will still be left with the choice of whether to keep the lights on or not. For this reason, it's important to consider your own safety and that of your family when making this decision.
Leaving house lights on all night is dangerous because it gives criminals easy access to your home while you're away. This can also be an energy wasteful practice. If you cannot afford to leave your lights on all night, try using timers or remote controls so you do not have to worry about them when you are asleep.
The cost of operating the lights is $0.2735236 each day, or $8.20 per month. Using the same technique of computation, a HID (high intensity discharge) lamp with a 600 watt bulb would cost me $30.90 per month. And if I left the room lights on all night, they would cost an additional $7.70.
Lamps that run on electricity rather than oil or gas have become increasingly popular over the past few decades. They are often called "environmentally friendly" because they use less energy and create fewer greenhouse gases than traditional lamps. But not all lamps that use electricity are created equal. There are two main types of electric lamps: compact fluorescent lamps (CFLs) and light-emitting diodes (LEDs).
CFLs were the first mass-marketed efficient alternative to conventional incandescent lamps. They use about 80 percent as much power as standard bulbs and last 10 times as long. In 2007, almost all CFLs sold in the United States were manufactured in China. The quality control problems caused by outsourcing have led many consumers to prefer original equipment manufacturers (OEM) products made in North America instead.
LEDs are becoming more popular than CFLs for several reasons. They are 100 percent recyclable, contain no mercury, and are extremely durable. They also produce very little heat.
The average family's lights are turned on for four hours every day. The average cost of electrical energy is 10 cents per kilowatt-hour (DTavg). That means that the average family pays $40 annually for their Christmas tree light show.
The good news is that modern LED lights are very efficient, with some models being able to last for several years before needing replacement. An evergreen tree will also help reduce your electricity bill by reducing its water consumption during dry seasons.
Christmas tree lights can range in price from about $15 for a small set of colored bulbs ($110 installed) to over $1,000 for a large display using white LEDs ($10,000 installed).
The high end of the market tends to use computer controlled lighting systems that are capable of displaying almost any scene possible with electronic graphics boards. These systems can be as expensive as $12,000 but may last for decades if cared for properly.
In general, higher quality lights are more energy efficient and last longer. They are also likely to give a better looking display than cheaper options. Christmas tree lights should never be plugged into an extension cord, as this will cause them to burn out faster.
