Think you know how a lightbulb works? Wait until you see this GE how-to video.

How many lamp owners does it take to change a high-tech lightbulb?

Actually, it may be more complicated than you’d think — and make you miss the good old days when all you had to do was screw it in.

But rest assured that the people at General Electric have put together an instructional video to show you how to troubleshoot the C by GE lightbulbs, and all that’s required is knowing how to count.

First, according to the narrator, turn off the lightbulb for five seconds.

Then turn it on for eight seconds.

Then turn it off for two seconds.

On for eight more seconds. Off for two more seconds. On for eight seconds. Off for two seconds. On for eight seconds. Off for two seconds. On for eight seconds. (Gasp!) Off for two more seconds.

Now turn it on, and it should work.

If not, maybe you missed a second or two somewhere. It’s unclear how much of an effect that would have, but GE does recommend counting using the “Mississippi” method — one Mississippi, two Mississippi, three Mississippi and so on.

At this point, you may be reaching a breaking point. If so, try a simple breathing exercise: Breathe in for four seconds. Hold your breath for four seconds. Exhale for four seconds.

The C by GE smart bulbs are Bluetooth-enabled, allowing users to set a schedule for their lights and control them with their voices, among other things. GE Lighting posted the tutorial on YouTube this year to show users how to troubleshoot by returning to factory settings.

But the three-minute video appears to have gained widespread attention this week after it was shared on Reddit and Twitter. It has since drawn hundreds of comments from people both mocking GE for its long-winded instructions as well as applauding it for its unintended comedy.

“This video made me forget about my soulless existence and feel alive for 8 seconds, then dead for 2 seconds, then alive for 8 seconds, then dead for 2 seconds, then,” one person commented on YouTube.

“I’m seriously hoping this is a parody,” one person tweeted. “Because, if it’s not, the GE smart bulb team should be charged with violating the Geneva Convention. This is torture.”

Another wrote: “I almost want to buy this lightbulb to see whether these instructions are real.”

Asked whether the video was intended to be comical, Mary Ann Milo, a spokeswoman for GE Lighting, said only that the company created it to help consumers reset the C by GE bulbs.

“We are aware that the current reset process for our smart bulbs is not ideal. We are working on simpler methods to reset products. We appreciate our consumers’ patience in the meantime,” Milo said in a statement Thursday to The Washington Post.

The tutorial also provides instructions for resetting a version of the lightbulb equipped with older software.

The process is slightly different for this one: Turn off the bulb for five seconds. On for eight seconds. Off for two seconds. On for two seconds. Off for two seconds. On for two seconds. Off for two seconds. On for two seconds. Off for two seconds. Turn on for eight seconds. Off for two seconds. On for eight seconds. Off for two seconds. And then turn it on one more time.

Thomas Edison may have just rolled over in his grave.

Pick the best LED light bulb for every room in your house

The right light for the right room matters. Here are our top tips.

Light bulbs have an enormous, everyday impact on the way our homes look and feel, and with a flood of new LED bulbs filling the lighting aisle, you’ve got more options than ever. But how do you pick the right lights for the job? The trick is to think about how you typically put light to use in the different rooms in your home. That, more than anything, will dictate your lighting needs.

For instance, you might benefit from an extra-bright bulb in your favorite reading lamp, but prefer a gentler, more candlelike glow from the lamp at your bedside.

To that end, here are some room-specific tips to help you zero in on the right lights for your living space. Where appropriate, I’ve also included links to buy some of the top bulbs from our tests — please note that CNET may get a share of revenue from those purchases.

If you have high ceilings, you’ll want floodlights that shine nice and bright in a single direction.

Lots of height? Make it bright
If you have rooms with high ceilings — an entryway, for instance, or maybe a staircase with overhead lights up above — you’ll want to prioritize brightness in your light bulbs. After all, the higher up your light bulbs are, the brighter they’ll need to be in order to light up the room.

The most common bulbs for overhead lighting are BR30-shaped floodlights. The “BR” stands for “bulging reflector,” and it means that the light inside the bulb sits above a reflective bowl, sort of like a little satellite dish. Screw a bulb like that up into your ceiling, and that bowl will catch all of the upward cast light, then reflect it back down and out the bottom, which bulges outward to cast the widest possible pool of light across the room. It’s the same trick your car’s headlights use to cast as much light as possible out in front of you as you drive.


Let’s look at your LED floodlight options

You’ve got plenty of BR30-shaped LED options in the lighting aisle. The most common among them are 65-watt replacement bulbs that typically put out about 650 lumens of brightness each. That’s a good, average number, and fine for average-height ceilings with at least a few bulbs shining overhead. Among the ones I’ve tested, 65-watt replacement floodlights from Cree and Philips are the two I’d recommend. They’re good values, they’re highly efficient (each draws less than 10 watts), they work well with dimmer switches and — most important for overhead lighting — they’re both nice and bright, each putting out comfortably more than 700 lumens.

If your ceilings are higher than average, or if you’ve got fewer bulbs shining overhead than you’d like, then look for 100-watt replacement BR30 LEDs that bump the brightness up even further.

Dimmability means versatility for your living room and bedroom
Some rooms serve just one or two basic functions, but other rooms get used in all sorts of ways. For instance, you might use your living room for watching TV, reading books, playing board games with the kids, or any other number of activities. Rooms like that can really benefit from lights that can adapt to whatever’s going on.


You can dim smart lights like this $15 Philips Hue White LED nice and low without any flicker or buzz.

The old-fashioned way to do it is to use a mix of different lamps and fixtures that serve different purposes — a reading lamp beside your favorite armchair, overhead lights for board game night, everything off when you’re watching a movie, and so on. That’s all well and good, but it limits you to a binary, “on/off” lighting mentality.

The better approach? Give yourself a full spectrum of lighting possibilities by making sure all of those lights can dim.

Upgrading your light switches to dimmer switches is one way to do it (and not nearly as intimidating as you might be thinking if you’ve never switched one out before). There are also smart plugs from brands like Lutron that’ll let you dim your lamps up and down.

The easiest way, however, is simply to upgrade your bulbs to smart bulbs. It’s a great time to do it — costs have come way down in recent years, and the advent of voice controls has given people a quick, easy way to jump to whatever setting they like, whenever they like.

Best of all, just about every smart bulb on the market will dim without flickering or buzzing, eliminating a common headache that comes with in-wall dimmer switches. That also makes smart bulbs especially good picks for bedrooms, where strong dimming performance and things like prescheduled wake-up fades can do wonders for your mood in the morning.

Consider colors in your kitchen and your closet
I’m not talking about color-changing smart lights (though if you want to jazz your home up with them, don’t let me stop you). No, I’m talking about the colors that are already in your home — artwork, furniture, the clothes in your closet, the fruits and veggies in your kitchen, you name it.

Whatever it is, if it’s colorful, then it’ll benefit from light bulbs with high color rendering scores — bulbs that help colors look their best. This isn’t always the easiest thing to shop for, as manufacturers aren’t required to list their color rendering scores on the packaging, like they are with brightness and efficiency specs. Some bulbs that do claim to be great with colors are actually just so-so.

My tip: Just stick with GE Reveal bulbs, because after about five years of reviewing light bulbs for CNET, I’ve yet to test one that hasn’t delivered on its promise of better-looking colors. That includes standard 60-watt replacement LEDs, floodlights, weird-looking stick-shaped LEDs and more. They tend to cost slightly more per bulb, and most are a little less bright than the average LED because they filter out some of excess yellow light — but those compromises are worth it if you’re using them to light up the spots in your home where you’ll appreciate accurate, better-looking colors day in and day out.

And that’s really the point — despite regularly taking them for granted, we use light bulbs more than just about anything else in our homes. They’re often the first things we turn on in the morning and the last things we turn off before going to bed. So don’t let the lighting aisle overwhelm you — finding the right lights for each room in your house is well worth it, and much easier than you might think.

Li-Fi edges closer as Signify backs the technology

SIGNIFY HAS bought another Li-Fi company in a major vote of confidence in the emerging technology.

The company, the world’s biggest lighting manufacturer, has purchased San Diego-based start up Firefly LiFi in what it described as a ‘strategic acquisition’.

The deal – reported in the Edison Report – follows Signify’s takeover in February 2017 of French Li-Fi developer Luciom.

Signify, formerly Philips Lighting, has 30 trials of the technology around the world. At last year’s Light + Building exhibition, company CEO Eric Rondolat said his ambition was to take Li-Fi – ‘light fidelity’ in which LED lighting provides a broadband Internet connection through light waves – into the mainstream.

The plan is that Signify would license its technology to OEMs, ensuring that the Li-Fi capability could be bundled in luminaires from different brands.

In another development, Li-Fi developer pureLiFi has unveiled the first ‘Gigabit’ Li-Fi platform for smart phones. At Mobile World Congress, the Scottish firm showed new optical components that will allow phone users to access ultra-fast 5G services from LED luminaires.


A Li-Fi installation at a cancer centre in Italy, is one of a large number of trials taking place around the world.The test project, at the Oncological Reference Centre in the National Cancer Institute in Aviano, is designed to explore if receiving data from the LED lights cut the electromagnetic interference with life-saving equipment such such as MRI scanners. The project is a collaboration between the University of Udine, the VDA Group and pureLiFi.

It also emerged this month that the US Army is trialling Li-Fi as a way of delivering secure battlefield communications.

This technology is being investigated by the Research, Development and Engineering Command Soldier Center’s Expeditionary Maneuver Support Directorate.

The technology will be used in temporary battlefield HQs known as ‘expeditionary mission commands’.

A key advantage for the army is that Li-Fi eliminates the problems associated with the time-consuming task of running data lines in tactical operation centres and command posts. Also, since the technology does not use radio waves, it cannot be detected outside the confines of the mission command platform.

‘The technology uses light waves to transmit and receive data between the servers and the user’s computer,’ said Melvin Jee, the leader of EMSD’s Command Post Platforms Branch. ‘As light cannot pass through walls, the enemy cannot detect the signal.’

The army is working with US Li-Fi manufacturer VLNComm.

Happy Thanksgiving 2018!!!

Wishing everyone a Happy Thanksgiving with friends and loved ones, from Commercial Lighting Tampa!

One step ahead: wireless emergency lighting solutions

Managing an emergency lighting installation in a large building is a very costly business, both in the time that it can take to physically check every luminaire and the associated labour cost of doing that work. If we add to those costs the need to keep a building fully operational even while emergency lighting tests call for batteries to be discharged, then it’s clear that we have to find a better solution to current practice.

Managing an emergency lighting installation in a large building is a very costly business, both in the time that it can take to physically check every luminaire and the associated labour cost of doing that work. If we add to those costs the need to keep a building fully operational even while emergency lighting tests call for batteries to be discharged, then it’s clear that we have to find a better solution to current practice.

Automatic testing is taking the place of regular physical inspections, but many of these systems call for additional control wiring to the luminaires. RP-Technik’s answer lies in the latest wireless technology.

RP-Technik introduced its WPS Wireless Professional System for automatic testing of emergency lighting in 2012. WPS covers all sizes of commercial operation. As well as Wireless Basic for self-contained emergency luminaire installations up to 50 luminaires (released in the first quarter of 2018), RP-Technik offers the WPS 2.1 system, which provides testing for wireless installations of up to 1,000 luminaires (each system). And by means of a common web-based interface (LAN), separate systems (be they wired central-battery systems or other WPS installations) in different parts of a building can all be controlled centrally, so it’s possible to integrate different installations into one single monitoring regime for up to 50,000 luminaires.

The Wireless Professional network operates at a radio frequency of 868MHz, which allows the installation of emergency lighting in areas where other sensitive electronic devices are in use, such as hospitals and laboratories.

RP-Technik Wireless Basic luminaires communicate via the Bluetooth low energy mesh network protocol. This means that each in-fixture wireless module is both a transmitter and receiver of information, building a single reliable and robust communications network.

However, Wireless Basic requires a mobile device (Android) while WPS requires a central station (PC) which must be installed and up running permanently – but, of course, can be placed at any location in the building.

Wireless technology also means that WPS 2.1 can be used when a building is undergoing a refit as well as new installations. It reduces cabling requirements and installation costs. In addition, luminaires can be added to the network at any time without requiring any major reconfiguring of the network.

The WPS system is designed to provide full statutory monitoring of the emergency lighting. Reporting can be scheduled according to need with status and error reports being delivered by email to the system administrator. As well as delivering data from the WPS network to local devices, records are also stored in the online portal Lightlinx, the RP cloud-based database (currently supporting Wireless Basic – support for WPS is in preparation).

The advantages of WPS at a glance:

• Easy installation – only 230V AC mains supply is needed

• Lower costs compared to cable-based systems

• Self-organising ad hoc wireless system

• Range between luminaires is a guaranteed 30m inside buildings (even through a concrete ceiling)

• Up to four times higher range than 2.4 GHz systems

• Resistant to DECT and WLAN signals

• 1,000 luminaires per system (expandable in steps of 250)

• Multi-language easy to use software

• No visible antenna at the luminaires

• Luminaires can be switched by timetable

• Status and error reports by email

• Log for daily/weekly function test stored in the central unit

• Capacity test of the battery for the whole operating time (usually three hours) possible

• Repeater for range extension available

• Switching of luminaires between non-maintained and maintained mode by software

• No faulty connection – no bus-line

• Monitoring system according to EN 62034 type (Wireless Basic is type ER, while WPS is type PERC).
