Your link is full of information on how many of these one can power from the source at a time-----not.
POE lighting can possibly have some usefulness, but not for lighting an entire floor or even an average size office room.Just seems like cat 5/6 and poe isnt the ideal cable for this. It was designed for other uses. That said, some sort of class 2 or 3 lighting system that is plug and play, could be a real time saver. Maybe we will see such things with the advent of lighting that uses less and less energy.
Daisy chain? Each fixture is a home run back to the POE switch just like a network jack.Your link is full of information on how many of these one can power from the source at a time-----not.
I know LED's are efficient compared to other light sources, but aren't we talking about 24 AWG conductors and only 24V (if that) max from the source? One cable is not going to power that many luminaires before it is overloaded - and that is even before considering what the source can deliver. One circuit with 12 AWG and 277 volts AC can possibly power all lights on entire floor in many places.
The IT guys, that's who.Who wants thousands of extra runs of network cable to run and terminate?
Hope that was sarcastic response. Large building probably still would cost less to run conventional 277 volts then all those CAT5/6 cables if every one of them needs a home run.Daisy chain? Each fixture is a home run back to the POE switch just like a network jack.
The IT guys, that's who.
I can recall the T8 revolution, followed by the T5's, only to be ousted by the LED oneAre you ready for POE lighting?
Looks like the IT geeks will be installing lighting now.
Not in Washington anyway, our state L&I made a change some years ago to restrict POE lighting to those who are certified, IE journeylevel, limited energy. Our telecom installers do not have to be certified, however telecom contractors are licensed.
well, as others have said, this dog won't hunt.
But properly terminated twisted pairs will minimize the radiated energy at that frequency independent of distance.notice it works at 434 Mhz... hmm... need to go back and check but, seems that a lot more interference can happen there as the frequency travels further... thus it is more liable to interfer with neighbors.. like a block away..lol...
OK, that takes care of the wire and connectors. How about the fixtures? No doubt the Chinese are sticklers when it comes to product performance...But properly terminated twisted pairs will minimize the radiated energy at that frequency independent of distance.

hmmm.. but all the system is touted as being wireless.. and not at the UHF frequencies but at VHF frequencies... would love to see how tight the frequency spacing and coding is gonna be on these... as even in Ham radio RC boats and car races, we had problems with interference and ask anyone who has been involved in the cb days just how much interference there is on channel 9 from stuff on chnnel 7 or 13...lolBut properly terminated twisted pairs will minimize the radiated energy at that frequency independent of distance.

Daisy chaining switches for additional ports can lead to several problems:I have never understood the way a lot of these guys in IT wire up places. I always used routers or switches.. wire from one to another and have a bunch of outlets in a new location.. daisy chaining... but the guys are taught to run only from one place now.. yet they still have all the switches and routers...
just ten times or more in wire...
and the code now... none of the new code writers could make Fortran work on a PDP 8 e
