I have an overhead light fixture using two

I have an overhead light fixture using two 100-watt-equivalent LED bulbs. The bulbs have been installed for about six months. Recently, when I turn the fixture on after it has been off overnight, one of the bulbs flickers briefly before fully coming on (this light is in my home office, so I rarely turn it off except overnight). Should I be worried about faulty wiring or a short in the fixture? The fixture is located in such a way that I can't test how tightly the bulb is in the socket without getting a tall ladder, which I don't have--but in any event, it seems that if it were loose, it would have been flickering before now, since the bulb has been in for a while. This is a standard switch, not a dimmer.

Our home has about 40 recessed 12-volt 50-watt MR16 bulbs, powered by a step-down transformer in each recessed can unit. If I switch to LED MR16 bulbs, will I save money? Or does the transformer itself use tons of electricity regardless of the 12-volt bulb type?

I have a strange electrical problem with a house built in

I have a strange electrical problem with a house built in 1980. While replacing some receptacles, I noticed that when I turned off the breaker and removed the wires from the old receptacle, it became "hot", and all of the LED lights in two rooms started blinking in a random pattern. I had to turn off two breakers to safely replace the receptacle. The break-away tab by the screw terminals was not clipped, which would normally be the case when one wants to isolate a duplex receptacle from another circuit. Now, the two breakers I had to turn off were on the same right side of the panel, so I would assume they're on the same phase. What gives?

I want to install LED rope lights on the inside of my roof on the outside patio. Currently these LED rope lights have a plug on the end of them. I Really want to cut off the plug and run it too a switch. I have a ceiling fan that is controlled by a switch and then I have another switch that would be controlled by the light on the ceiling fan, but the fan that is installed does not have a light attached to it. Can I use THAT switch to control my LED rope lights and what's the best way to connect the two together
