LED Wireless Motion Sensor Light FAQ

Have questions on your Mr Beams LED wireless motion sensor light? Check out our frequently asked questions below, including how the lights work, how long the batteries last and the different types of lights we offer. If you don't see your question here, please contact us for additional support!

How do Mr Beams LED wireless motion sensor lights work?

All Mr Beams lights (except the UltraBright Lantern) have light sensors, motion sensors and auto-shut off. This allows the lights to only work in darkness, when motion is sensed and will shut off after the auto-shut off time listed in the instructions. View our Installation Videos for more details on the product you are interested in. 

How do I test my Mr Beams motion sensing light?

To test a Mr Beams Motion Sensing Light before installation or at any time, it is recommended to always use fresh batteries and take it into a dark room. Leave the room to avoid your motion retriggering it. The light will shut off after a minute or two (the motion sensor may need time to settle immediately after putting the batteries in). When you walk into the room, the motion sensor should trigger turning the light on. We recommend waiting for the auto shut off to turn the light off prior to installing to verify there are not issues with the batteries you've inserted.

Do I need special batteries for my Mr Beams motion sensing light?

You can purchase regular alkaline batteries at any store. If preferred, you can also purchase NiMH rechargeable batteries. See more information on batteries here.

How often will I need to replace batteries?

Each light is designed to get one year’s worth of light on each set of batteries with average use of 8-10 activations a day. If your lights are in a high traffic area or are exposed to extreme temperatures, your battery lifespan will be less than one year.

How do I install my light?

Please visit the support section and find the user manual and installation video for each product. 

Do you offer a motion sensing light that will activate in daylight?

All Mr Beams LED wireless motion sensor lights were designed to only activate in darkness. However, if you’d like to install a light in a location that may not be dark enough, we have offered to remove the light sensor as a special request. If you’ve already purchased your light and would like further instruction on removing the light sensor yourself, please go to the following page mrbeams.com/information-docs.

Do you offer a motion sensing light that stays on for long periods of time?

Currently, the majority of our Mr. Beams LED wireless motion sensor lights were designed with an auto shut-off feature to conserve battery life. Without the auto-shut off you run the risk of draining your batteries within a short period of time. However, we do now offer a new MB371/MB370 spotlight, which will allow you to leave your light on for 1 or 4 hour periods. Since this product offers 3 levels of brightness, you can also help control the battery drain by lowering the lumens when the light is on for an extended time. In addition, our ReadyBright line of battery operated products can be used as a portable lighting system, allowing you to use the remote to turn the lights on and off for up to 40 hours.

Can Mr Beams products be used outdoors?

Yes! All of our Mr Beams products were designed with weatherproof seals to hold up in harsh weathers and water – with the exception of the MB852 / MB862 Slim Lights and the MB702 / MB706 Mini Stick Anywhere LightsNote- Mr Beams products are water-resistant, but should not be submerged in water.

Will cold weather affect my light?

Your Mr Beams light will not be affected by cold weather, however, the light may appear dimmer in colder weather because the batteries are providing less power. We recommend Lithium batteries if you live in colder temperatures. To learn more about the best battery choice for cold temperatures click here.

What are lumens?

A lumen is the total amount of light emitted by a light source. More lumens means more light. Mr Beams lights are anywhere between 10 lumens (Stick Anywhere Night Light) and 300 lumens (UltraBright Spotlight). To find out how many lumens and what product(s) would work for your needs, check out our Brightness Comparison images to see how bright each of our LED lights are.  

Where can I find user guides and installation guides for your products?

If you happen to lose your user guide, you can click on the User Guide tab under the Support section. From there you can download a PDF version of any Mr Beams user manual. 

The user guide is confusing; is there another way for me to learn how to install my light?

As an alternative to user guides, we also have installation videos for each Mr Beams product. There are two ways to get to your respective installation video: you can either go to your product page and click on the installation video tab right below the product specifications or you can find a list of any Mr Beams installation video under the Support tab.
