Mr. Bean Firing Gun

You can leave LED lights on all night, but it is advisable to avoid leaving them on 24/7. LED lights have a long lifespan, but they still degrade over time, and leaving them on all the time can shorten their lifespan. Additionally, leaving lights on unnecessarily wastes energy and increases energy costs. It is more energy-efficient to turn off lights when they are not needed. 

Besides carbon footprint and electricity costs, you should also consider the impact of these lights on your health. Excessive exposure to LED lights can interfere with your circadian rhythm, blurring the distinction between days and nights. This may lead to poor sleep at night and poor productivity and focus during the daytime.

You can use some quality alternatives (detailed in this article) to turn your lights on and off automatically. This way, you can optimize electricity usage as well as prevent night-time light from interfering with the sleep pattern and quality of your elderly roommate.

How Long Can LED Strip Lights Stay On? 

LED Strip lights can stay on for as long as 50,000 hours. These light strips are a better alternative to LED lights for use at night as you can dim them at will.

When it comes to keeping LED strips on for extended periods, another common concern is do LED light strips burn out. Fortunately, they don’t. You can leave strip LED lights on all night without worrying. 

The same is the case with string lights or battery-powered LED lights. You can keep these LEDs illuminated for as long as you have charged them for the extended duty. However, to avoid paying outrageous electricity bills, it’s recommended to keep your LEDs off when you can.

What About Special LED Lights…

Below, we take a quick sneak peek into some special-purpose LEDs and the ideal duration for which we can leave them on:

Are Grow Lights Safe To Leave On All Night?

Yes, it is safe to leave Grow lights on all night, but their 24/7 exposure to the plants can harm your plants’ health. Plants need around 12 out of 24 hours period to rest. But grow lights will keep their food production function on, taking away their much-needed rest.

The overnight consumption of grow lights doesn’t cause a fire – that’s a given. But you still wouldn’t want to keep them on for the safety and nourishment of your plants.

Can You Leave LED Christmas Lights On All Night?

As is typical with LED lights, Christmas lights can be left on all night and even 24/7. The concern here Is not the safety of having Christmas lights on all night, as Christmas lights are safe to keep on all night. Instead, the matter at stake is the cost-effectiveness of having them illuminated around the clock.

Your electricity bill will likely spike if you decorate your home or a large area for a commercial celebration. So understandably, your electricity bill will determine if your LED Christmas lights should stay on all night.

How Much Does It Cost To Leave LED Lights On 24/7? 

LED lights are far more energy efficient than their traditional counterparts. Generally, an average 15 Watt LED lightbulb (450-1600 Lumens) uses about 0.015 kWh for an hour. This electricity consumption is billed at around 16.09¢ for each KWh. So, leaving LED lights on 24/7 costs you around $0.2413 per hour.

Electricity Cost of Leaving an LED Bulb On 24/7

Using this information, we can compute the cost of leaving LED lights on 24/7 for different periods:

LED Bulb PowerDuration of Energy ConsumptionFormula for CalculationCost of Leaving LED Lights on 24/7
15 Watt LED bulb1 day (24 hours)Electricity cost per hour X total hours in a day$0.2413 x 24 = $5.7924
15 Watt LED bulb1 Week (168 hours)Electricity cost per hour X total hours in a week $0.2413 x 168 = $40.546
15 Watt LED bulb1 Month (730 hours)Electricity cost per hour X total hours in a month$0.2413 x 730 = $176.14
15 Watt LED bulb1 Year (8760 hours)Electricity cost per hour X total hours in a year$0.2413 x 8760 = $2113.78

To further simplify how much an LED light costs you, let’s compare it with the cost of traditional light. A 60-watt incandescent bulb costs you around $8457.83 per year. Comparing this electricity bill with a 15-watt LED bulb, you can save about $6344.05 in electricity costs in just one year. 

Note that fluorescent bulbs will consume far less energy than incandescent light and are only marginally costlier than LED lights. However, LEDs win the battle as they are the most cost-effective and safest lighting option.

Can You Sleep With LED Lights On?

LED light exposure shouldn’t affect your sleep cycle if you don’t usually struggle with a sleep disorder. You should, however, look out for the blue lights as they can jeopardize the quality of your sleep

Blue lights can interfere with the brain’s function of melatonin production, a sleep-regulating hormone. Continued disruption of melatonin production can induce sleep disturbances and disorders.

You may experience the following 6 symptoms if you continue sleeping with LED lights on.

  • Delayed onset of sleep
  • Difficulty remaining asleep 
  • Poor metabolism
  • Cardiovascular ailments 
  • Lapses in cognition 
  • Mood disorders 

Can Leaving a Light On at Night Cause a Fire?

Leaving LED lights on all night or 24/7 cannot cause a fire outbreak. However, the case might be different if you have traditional lights installed. 

Incandescent bulbs create more heat than light. A 60-watt bulb can cause the paper wrapped around it to catch fire within 20 minutes. Of course, using these lights will be safe under normal conditions when they stay away from flammable objects.

One, however, should not disregard the possibility of melting this bulb’s metal base, causing an explosion. Although the possibility is rare, it poses a severe fire hazard risk because of its potential impact.

When Is It Best To Leave LED Lights On All The Time?

Although it is not wise to keep your lights illuminated around the clock, some conditions leave you with no better option. Below are some exceptional circumstances under which you should consider keeping your LED lights on for extended hours:

  • Elderly citizens or disabled people may want to keep the lights on to prevent a falling accident on their late-night bathroom trips.
  • If you are a new parent, you would want to leave the light illuminated in the doorway to the nursery. Doing so will help you reach the child promptly despite your sleep deprivation.
  • All-night lighting becomes necessary near stressful exam days or during busy months in your family business.
  • Some people have adjusted their sleep patterns to night lights, and switching off these lights may interrupt their sleep. If you count yourself as a native of this night-light tribe, keeping your room lit all the time would be better.
  • Leave your lights on at night, too, if you have Nyctophobia (fear of the dark) that induces a startle response and jerks you awake as soon as the lights are turned off.

While some of these reasons demand keeping the lights on all night, others are flexible and can work well with alternative solutions.

Safety Considerations to Illuminate Your Home Safely 24/7

If you have to leave the lights on all night, be mindful of their safety and follow these necessary precautions:

  • Switch to LED lights instead of CFL or incandescent lights.
  • Do not leave timeworn lights on at night. Although LEDs are considered prone to the risk of burning, newer lights are far safer than older ones in this respect.
  • Check the ambiance of your night lights. These lights shouldn’t be enclosed or may get hot sooner, leading to a higher fire risk.
  • Keep easily or highly flammable objects away from your illuminated lights.

3 Alternatives to Leaving Lights On Overnight 

If fear of darkness isn’t your reason to leave LED lights on all night, consider the alternatives to night-time lighting, as they may be safer and more energy efficient for your home.

Here are three of the best overnight lighting alternatives that we’ve picked out for you:

1. Motion Sensors

If you dread leaving your comfy bed at night to turn off the unnecessary lights, lights with motion sensors are your best friend.

2. Smart Home Technology

A rather costly option is to equip your home with smart home technology. Smart home technology lights or smart lights can be controlled and automated through a program such as a smartphone app, voice assistant, or other smart devices. 

You can command your smart home assistant to schedule them to turn on and off at specific times and set them to simulate your presence while away from home. Some smart lights also feature color changing and adjustable brightness, allowing for a customizable lighting experience.

3. Automatic Lighting Systems

An automatic lighting system is a lifesaver if you habitually forget to turn off lights after leaving a room. It’s also a fantastic solution to fight the fear of darkness. Simply command the system to gradually dim the lights as you drift off to sleep. Once you’ve conquered your fear in the warm glow of dimmed lights, it’s time to weigh the options — is it better to sleep with or without LED lights?
