In an earlier comment, I posted an image of the back of both podiums, taken before the debate. That image shows there are two wires branching off from the power source installed through the floor. So it would seem that both podiums might have been identically wired. Hillary's light turned on as she walked towards the podium, but Trump's did not.
There might be another reason. Her face is lit from below. It's far more flattering. An overhead light casts shadows on a face and neck; now we might see why her face is illuminated - it was a trick to make her look younger, and Trump, whose light wasn't turned on, doesn't benefit from the lighting. His light wasn't turned on deliberately so that he would look older.
Heaven knows, she needs all the help she can get. The rest was all a matter of having copious notes to quote from, as we see her reading, the obvious collusion from the moderator, and of course, the written material had to be removed after she left the podium. I think that might just about cover it.
Not saying there was no LED reading device installed, but that light had an effect all of its own, and it switched on and off when the microphone was turned on and off. The light in Trump's podium did not work, and his microphone was faulty. Nasty nasty...
