Best Battery Powered Security Lights

You might be wondering what those terms you see on the box or label of your outdoor security light mean.

Well, here are some of those terms that typically describe a feature of your security light.

It should give you a fairly good idea of the security light you bought.


Lumens are the new standard of measuring the amount of light that a certain light source gives.

It is an indication of the brightness and intensity of light that your light source emits.

The higher the lumen rating is, the brighter and more intense the light is.

Conversely, the lower the lumen rating, the dimmer and weaker the light. 500 lumens is bright and can cover a larger area (e.g. a 800 sq ft yard), as compared to 200 lumens which is probably ideal for garage doors and doorways.

Understanding the concept of lumens gives you a more accurate gauge of what kind of light you may need.

We used to gauge the kind of light we need through watts.

It works the same as lumens, i.e. the higher the wattage, the brighter; the lower the wattage, the dimmer.

While this may be generally true, watts is not an accurate measure of the amount of light or the brightness of light.

Watts simply tells you how much electric current (energy) the light source needs to operate.

LED (Light Emitting Diode)

LEDs are the new standard in light fixtures.

LEDs are more economical to operate than both CFL and incandescent lights.

If you’ve seen a traditional drawing of a light bulb, with a coil of wire that arcs from one side of its base to the other, emitting a bright yellow glow inside a glass sphere — it’s an incandescent bulb.

The coil of wire (filament) is very fragile and easily burns out or breaks — a little shake can break it. 

An incandescent bulb can give you the same brightness as an LED but it will require more energy.

The CFL (compact fluorescent lamp) operates in the same way as the old fluorescent tubes, but in a more advanced and compact (often spiral) way.

It is more economical to operate than incandescent light, but still uses a heat source for the lamps to light.

They also require more energy.

And this makes it hot. Both CFL and incandescent lights are types of lighting that get hot. 

LEDs do not rely on a large amount of heat and current to light up.

LEDs use tiny little (microscopic) semiconductors that cause tiny little diodes to be energized and produce a glow.

LEDs are cool (literally).


Because of the efficiency of LEDs in producing bright light, outdoor security lights are often battery-powered.

Most battery-powered security lights use dry cell batteries of different sizes, including AA, C, and D.

Others, however, use rechargeable lithium ion batteries.

The longest a battery is expected to last in an active (8 – 10 activations per day) security camera with motion sensor is 1 year.

Most Mr Beams security lights give this guarantee. 

Motion Detection and Range 

Motion sensors have a range from a few feet to 100 ft. It varies on specific products and the desired range you set.

You might not want to set your motion sensors where there is a lot of foot traffic or vehicular traffic, because these will likely trigger your motion sensors.

You can set your motion detectors from 10 – 15 ft or 30 – 40 ft, which are average distances outside your house and near your perimeter fence/wall, respectively.

Weatherproof (IP Rating)

Many brands of outdoor security lights generally describe their lights as weatherproof.

By weatherproof, manufacturers generally mean your light unit can withstand strong winds, rain, sleet, and snow.

But if they indicate on the label an IP rating, it’s usually more specific.

It could either be IP44 or IP65. 

An IP44 means your unit is protected from solid objects 1mm or larger, and from water splashes (from all directions).

An IP65 rating (obviously higher) means your unit is vacuum sealed and is protected against small dust particles, and low-pressure water jets.

Pros and Cons of Battery-powered, Solar-powered, and Electricity-powered Security Lights.

1) Convenience.

The greatest advantage of battery-powered is convenience of installation.

You can install it anywhere where there’s no electricity. You don’t need to connect it to any power outlet or to main electricity lines.

Also, battery-powered leave no hanging or crawling wires that can be a hazard.

Another advantage of battery-powered lights is they are easier to handle, more lightweight, and can install anywhere and with little effort.

Mr Beams security lights, for instance, installs in just 5 minutes.

On the other hand, electricity-powered lights obviously need a power outlet or otherwise, extension cords.

If you will connect your security lights to a mainline, it will require an electrician to do the job.

It will cost you more to install electricity-powered lights.

Solar-powered lights fall somewhere in between. Some are easier to install and maintain than others.

2) Consistency.

Because batteries die down sooner or later, battery-powered lights tend to lose brightness or even malfunction when batteries grow weak and lose power.

The same goes for solar-powered, since sooner or later your solar panels will get old and worn out, you won’t get good illumination, and will need replacement or repair.

Electricity powered security lights have all the advantage, because of consistent power supply.

Electric-powered lights give brighter and more consistent year-round lighting.

Consistency of power source will prove to be a problem with the motion detection capability of your battery- and solar-powered security lights.

Always check and make sure the motion sensors are working in good order.

3) Maintenance.

Battery replacement is cheaper for battery-operated lights.

Solar batteries are very expensive, but takes a long time (5 – 7 yrs) to wear out. 

Electric-powered lights need no battery replacement, but would require a professional electrician when something goes wrong with the system.

The Story of Mr Beams

One of the more popular brand names in security lights is Mr Beams.

They have about 40 different types of security lights, and indoor and outdoor lamps for your household and security needs. Almost all of their lights are battery-powered.

There’s a reason why.

Mr Beams was founded in 2004 by a couple of guys who were looking for a light for their closet.

When they couldn’t find one that was simple and easy to install, they made it themselves.

That’s where Mr Beams all began. They have been making simple, easy to install, lightweight battery-powered lights since then.

Mr Beams lights are designed and guaranteed to last 1 year on a new set of batteries.

This is for an average of 8 – 10 activations per day. They are easy to handle and very practical — it takes only 5 minutes to install.

And you can install them anywhere because they do not require a power outlet.


1) What is the difference between lumens and wattage?

The difference between lumens and wattage revolves around what they actually measure.

Lumens measures brightness or intensity of light.

Wattage measures electric current.

Lumens tells you this is the amount of light that a particular bulb will give you.

Watts tells you this is the amount of electricity that a particular light needs to produce light.

Lumens is a specific measurement applying to light.

Watts is a general measurement applying to electrical devices and appliances, e.g. flat iron, electric fan, dish washer. But there is a certain correlation between the two — the higher the number, the brighter the light.

So a 100w bulb is usually brighter than a 60w bulb. And a 500lm bulb usually brighter than a 200lm.

2) How many lumens do I need for outdoor security lighting?

Lumens tell you the amount of light in terms of numbers.

But it really doesn’t tell you how many lumens you need for your outdoor lighting.

For that, experience will be your best teacher.

But you can also refer to industry standards as to how large an area a given number of lumens can illuminate.

Here are some:

a) Step lights, wall (wallscape) lights, small landscapes — 100 lumens.
b) Path lights, medium landscapes — 200 lumens.
c) Pool and pond lights, wider landscapes — 300 lumens.
d) Motion sensor lights — 300 – 700 lumens.
e) Flood lights — 700 – 1,600 lumens

3) What is the ideal range of motion sensor for outdoors?

The ideal range for your motion sensor would be right next to your perimeter wall or fence, and several feet from your house.

This way, your system will be activated and its alarm will trigger when there is a breach on your perimeter and when undesirable moving objects approach your house.

You can set your motion detectors from 10 – 15 ft or 30 – 40 ft, which are average distances outside your house and near your perimeter fence/wall, respectively.

4) Can motion sensor lights be set to stay on?

Motion sensor lights usually turn off automatically after 10 – 30 sec where no further motion is detected, depending on the particular brand model.

There are some brand models that can be manually set to stay on, and function much like a regular spotlight.

The Mr Beams MB370 has a more advanced feature since its override system can be operated by remote control.

This way the light on your motion sensor stays on longer.

5) How bright is 50 lumens?

The standard equation for understanding the relationship between watts and lumens is: 1 watt = 11.25 lumens. Broadly speaking.

So, to produce 50 lumens of brightness you need, 50 ÷ 11.25 = 4.44 watts of electricity.

So, if you have a 4 or 5 watt bulb, it’s equivalent to 50lm of light.

6) What is the difference between PIR and motion sensor?

Typical motions sensors use microwave or radar signals to detect motion.

They rely on shapes, and are triggered when an object (shape) or an image bounces back on their receivers.

When this happens, the processor will send an instruction (electronic signal) to a device attached to the system.

This is the kind of motion sensor that automatically opens sliding glass doors in departments stores and various buildings. 

However, most outdoor security lights use a PIR (Passive Infrared) system.

This system detects temperature changes in the surrounding air. It is often set to trigger within the range of your normal body temperature, e.g. 99ºF (37ºC).

When the detector is triggered, it automatically switches on the security lights.

In some systems a video camera is also activated, together with an internal alarm system.

The Mr Beams MBN354 has the additional feature of sending signals to other security lights in its zone to also switch on, when one is activated.
