I want to wire 4 Philips CorePro 13W Led Bulbs together. They each got a seperate driver inside them. What is better way to wire them and why parallel or in series?
He's talking about connecting 4 screw-in led bulbs. Just connect each pair of conductors from the lamp sockets to a common buss and then that buss is connected to your ac line in. Nothing special-it works just like all of the wiring in your house.
