Cold Weather Operation of Mr Beams Wireless LED Lights

Every winter, we get a few questions about how well Mr Beams Wireless LED Lights will work in very cold environments. One attribute of LEDs that makes them ideal for outdoor applications is their extended temperature range. LED lights can be very durable in cold environments however every component that makes up the LED battery powered light needs to have an extended temperature range.

Taking this into consideration, Mr Beams Wireless LED lights have an operating temperature range of -4 degrees F to 140 degrees F at a relative humidity of 90% (-20 degrees C to 60 degrees C at a relative humidity of 90%). We do this by selecting every component in our products to meet or exceed this temperature range.

To make sure a product can operate over the extreme temperature range, only batteries with an extended temperature range can be used. Energizer, Duracell, Panasonic and other battery manufacturers offer an industrial temperature range battery. Let's take the example of an Energizer Industrial D Size Alkaline battery. The datasheet for this battery on the Energizer website is http://data.energizer.com/PDFs/EN95.pdf. It has a temperature range of 0 degrees F to 130 degrees F (-18 degrees C to 55 degrees C). The specification for the battery sets the operating temperature of the Mr Beams MB360 Battery Powered LED Security Spotlight with this battery installed. That is still a pretty good operating temperature.

One important point though is that light output will decrease at the very low temperatures. Why? The efficiency of the LED actually improves at colder temperatures (ie more light is generated for the amount of power consumed from the battery) so that cannot be the reason. It turns out that the battery performance is considerably reduced at the lower temperatures. Looking at this technical bulletin on the Energizer website at http://data.energizer.com/PDFs/BatteryIR.pdf, you can see in Figure 2 that the internal resistance of the battery increases at the lower temperature. The higher internal resistance of the battery hurts the battery performance. It impacts the performance of the light to more than offset the increase in LED performance therefore overall the light output is decreased. We estimate that the lumen output of any wireless LED light at lower temperatures may drop as much as 20% based on the degradation in performance of the battery in cold weather.

The bottom line is that Mr Beams Wireless LED lights have been installed and working at low temperatures for years. They are a great solution for outdoor lighting in cold weather environments. If you have a cold weather lighting application, we hope you will consider the Mr Beams LED lights.

Lights to Help Louisiana and Mississippi

I’m watching the opening NFL game – Vikings at Saints in New Orleans. With the five-year anniversary of Hurricane Katrina, there have been many videos replayed showing the unbelievable damage and destruction to the infrastructure. Electricity was out for months.

The Mr. Beams™ line of battery-powered LED lights was not yet invented. Lighting is the function that people miss most when electricity is out. We wish we could have provided our LED motion sensor lights to the people affected by Katrina. We recognize that people are still recovering from the impact and are offering two for one Mr. Beams lights to any residents of Louisiana and Mississippi. We will automatically double your order if placed at www.mrbeams.com

We recommend the following products: the MB980 Ceiling Light to light closets, pantries, attics and sheds. It has a motion sensor and a bright 80-lumen Nichia LED. It is a weatherproof light that can also light up a porch or gazebo.

The MB360 Spotlight can provide safety and security lighting for the perimeter of your home. With the motion sensor the Spotlight turns on and lights up intruders or animals. It can provide safety lighting – it can attach to a tree and light up your driveway, walkway and back door.

The MB530 Stair Light lights up stairs. This is particularly important to prevent falls inside and outside your home. With a motion sensor and a bright LED, the Mr. Beams Stair Light will light up stairs and hallways. When you wake up at night to go to the bathroom, the Stair Light will detect you and light up the hallway or stairs. It even glows all night to show you where it is.

Prepare for power outages with the battery-powered lights from Mr. Beams. And if you live in Louisiana or Mississippi, we will automatically double your order on www.mrbeams.com

Celebrate Innovation on Labor Day

An advisor to Mr. Beams recently said he wanted to brainstorm about new products. This guy is a brilliant product developer who has created big product lines that have revolutionized lighting controls. His prerequisite for helping us was that we create breakthrough products, and not just slight improvements. His statement first created an energy and excitement for me that I get when allowed to dream big dreams. It was then followed by the part of my brain that remembers how intense and grinding it is to truly innovate. In my early days as a product manager I could not wait to launch my first product line. It was with Black & Decker in their power tool division and I owned every element of the product line – the feel, the color, the motor, the box, the accessories, the user manual. I was not yet married and that allowed me to spend late nights at the office - it consumed me. But it needed to consume me in order to innovate in a field where everything had been done already.

Innovation in many consumer products has slowed down. Part of it is because of the recession, but I believe there is a more nefarious reason. The power wielded by so few retailers has created greater barriers for entry to smaller companies. Often it is the smaller companies that innovate, but the possible reward of a successful product is now lower because the largest retailers do not want to work with smaller companies. Large Retail knows it limits the innovation that they can offer their shoppers, but it makes logistics so much easier for them. If they are buying 30 items from Category Manager A, and they like 2 products better from a smaller company, they are not going to set up a new vendor of questionable shipping abilities to provide those 2 products. Instead they buy the unimaginative version from the incumbent.

At first this did not limit innovation so much – the larger companies were still investing in new ideas and generating innovative products. But soon the consolidation of retailers meant that 3-5 companies made up 90% of their revenue. They now need these companies to like their products. So here is how new products are now developed: the VP of Sales for a company calls on Big Box Buyer and brings sketches of 5 product ideas. They have learned that getting buy-in from Big Box Buyer is the key to get new products placed. So they ask Big Box Buyer her opinion and she prefers one concept. VP of Sales leaves the meeting and immediately calls the product manager and tells him what the next product will be. Suddenly that new product is the darling of the product management team and gets priority resources.

Is this innovation? I would argue that Big Box Buyer knows her customer best. But the customer only knows what they have already seen, experienced and used. There is a possibility for incremental improvement in the product. But the chance of Big Box Buyer picking out a breakthrough product is slim.

Small companies do not have access to Big Box Buyer. We innovate by observing how people live, what they struggle with and what they enjoy. We know that an incremental improvement won’t cut it, so we work harder and risk more for that product that makes people fall in love with them. As I write this I am listening to a product that does that – it is a Sonos Digital Music System. I can pull up any song anywhere through one hand-held device. Every few months the smart people at Sonos add another great feature. I access Rhapsody, XM Radio, iheartradio through this system and can play different songs or radio stations in different rooms. These team at Sonos observed how people want to access and interact with music and are constantly working on improving the joy that the product provides.

Why am I wasting precious blog space on innovation rather than promoting my products? Probably because it is Labor Day today and days like this separate the innovators from the entrenched. Innovators hate these one-day holidays because no innovation gets done. People at large companies love these days because they get paid for doing their own thing. Have we innovated at Mr. Beams? I think so. We make the world’s best wireless LED lights. We are creating a system of emergency lighting for homes that will automatically provide light in the event of a power outage. We make the best Closet Light you ever installed on your own. We have used motion sensors and bright battery powered LED lights to eliminate darkness in so many places in a home. We have prevented countless falls due to dark hallways and stairs. When my 90-year-old Aunt Mille calls me the first thing she says in her Brooklyn accent is “Oh David that light you sent me is my favorite possession. I get up to go to the bathroom twice a night and that light goes on every time so I can find my way.” To me that is more rewarding than anything Big Box Buyer can say. So support your small company and please recognize that there is tremendous innovation in alternative distribution channels - like www.mrbeams.com

Jeff The Intern

This summer, we've been blessed with a college intern. Jeff has been our "go to" for all necessary tasks that take us away from our daily activities. If you called or e-mailed Wireless Environment between June 1 and now, chances are Jeff was involved in your inquiry.

Mr Beams began providing its LED motion sensing lights to the public in 2008. For two years we have been enjoying the process of getting acquainted with different industries and markets, trying to determine exactly what our customers want. In addition to a quality light that helps to brighten all of the different places where light is not available, we have learned that customer service is the most important facet of our business. Our summer intern, Jeff, is a testimony to good service. Testing every sample that goes out, owning the shipping process, visiting the post office (sometimes multiple times a day!) and responding to customer needs quickly are just some of the ways that Jeff has helped our business this summer.

Jeff has enthusiastically sold product out of his car (that's right, he peddled an Anywhere Ceiling Light to his grandfather), delivered samples to a local handyman and actively followed up on his sales efforts, not necessarily to close the deal, but to find out exactly what people like about our products and what we could be doing better--because that's what is important to Jeff.

As an avid "Simpsons" fan, Jeff could be heard chuckling over Homer Simpson tumbling down the basement stairs and commenting, "if he had a Mr Beams light, he wouldn't have fallen." I know that, when Jeff heads back to school I will be reminded of him when I employ our Test Customer, whose address is the same as the Simpson family's.

Jeff's smile is as bright as our Spotlight and we know that his sense of humor and clever wit will spread joy across the campus of the University of Toledo in just a few weeks. You can listen for Jeff's guest spots on WXUT radio in Toledo, OH. Our office will be a bit quieter when he's gone but his inventory and pretzels will be a reminder that Jeff will be back for winter break. Best of luck, Jeffrey. We'll miss you!
