I've been watching this for a couple of years. We control lighting with our security systems like many other companies. It's kind of old school the way it's done. I'm excited to see security applications for this.

Wow! I remember a sales engineer I worked with a decade ago mentioned something like this would be occurring in the future. I wrote it off as I had never seen anything mentioning this application. It's not as though I read lighting trade magazines! This is a great article, truly broadening the horizon, and will definitely be investigated further.

I've heard of this trend being referred to as the "Digital Ceiling", which includes other IoT-ish things like adding in networked HVAC sensors and people counters.

sweet. Are the lights just a dumb device, meaning they just use the POE power of the switch and have no real network traffic associated with them, or do they actually have web servers built in where you can turn them on/off over the network.
Or are they using proprietary managed switches for that instead of each light having web servers?

This should prove interesting when the lighting is required exit lighting.
Although it may seem economical when using open wiring, when conduit is required there will still need to be outlets nearby on the walls until someone comes up with POE appliances and such.
It's certainly an improvement on the old Lutron way of lighting control with a ton of control wires and relays...and I mean OLD Lutron, not anything they may do today.

Good Luck in this space for security integrator!!! Been there! Also Redwood / Commscope already disbanded the line.
Extreeeeemly high initial cost over convention fixtures with LED bulbs. And the even more difficult part is the design/build is entirely covered by the electrical core division and rarely / rather never to this date makes it to a Div 26/27 scope.
Even a retro fit is difficult as the cost to remove existing fixtures by an actual electrician is more than the cost of replacing the bulbs to LED.
POE lighting is not the way Redwood did it, they had their own appliance and although it used RJ45 ports and looked like switch it used 6 wires strictly for power, no Ethernet data, a contact closure for a ceiling mounted motion detector on the last pair.
I cant imagine buying a POE switch to power a light bulb, the POE port would cost nearly as much as a standard fixture alone.
Awesome concept hopefully it will take off in our realm in the coming years, but I dont see us taking work from electrical space here.

The next step is allready there as well, check out VLC or Visual Light Communication. The LED lights are used to communicate with smart devices such as smartphones, tablets etc. This has the potential to replace WiFi in certain applications. there are allready field trials for instance in Carrefour Supermarkets in France where the technology is used to 'guide' customers to the products, share coupons and collect occupancie and stuff. Redwood was an early adopter but the advancements in technology and applications are huge.
by now it's much much more than just powering lights over the network, it's all about gathering information

Our lower-lumen LED lighting has been reliable and effective, but we've had very uneven results with high wattage PAR30/BR30 E27-based LED lighting. All of our Philips, Starpower, and Fait are still going strong after two years, but nearly 100% of the "100W equivalent" models from Lighting Ever and G7 Power failed within the first six months of operation.
Given the significant unit costs, whether low voltage or E27, I hope high-lumen LED reliability is improving. In our experience, the more reliable low-lumen LEDs are a solution in search of a problem -- they don't fulfill our needs.

For anyone who watched the mr robot episode where the smart house was hacked, imagine these lights getting hacked and being messed with lol

In the article 3 manufacturers are mentioned.
Iluminar , Raytec and NuOptic.
Raytec I know. Can anyone tell me about their experience with the other 2?

The biggest issue I see here is the inability to daisy chain.
Assuming 1:1 port device ratio, I see little advantage in running a gazillion ethernet cables through a ceiling.
Standard electrical lights have the convenience of being able to daisy chain banks of lights on 1 circuit reducing cabling costs because all you need to do is run 1 cable and apply the snap on sockets.

I've been saying for years that almost everything minor appliance in a building will be heading POE...
there'll be POE powered desktop PC's, monitors, already we have Phones.
imagine a world where every light switch and bulb socket are POE...where security sensors, smoke alarms, thermostats, temperature sensors, screamers, sounders, light fittings are all POE...
in the not too distant future only the big things'll require dedicated mains sockets or wiring, can't see POE fridges, microwaves or kettles any time soon :-)

I include Totus in this line of thinking, since they directly integrate Axis and Mobotix 360-degree cameras into their lighting solutions. Not PoE, but still very forward thinking and absolutely suitable for parking lots!
