The requirements of a lighting application often dictate what type of circuit can be used but if given the choice the most efficient way to run high power leds is using a series circuit with a constant current led driver. If you wire lights in series theyll all go out when one of them fails.
A Light Fixture Wiring Dilemma
Wiring light fixtures in series. Rate this question and its answers know the answer or have a comment. Wiring lights in series results in the supply or source voltage being divided up among all the connected lights with the total voltage across the entire circuit being equal to the supply voltage. When wiring 110 volt wire to 5 light fixtures in series do i connect the white wire to the fixture or splice to another white wire at each fixture. Tighten the mounting screws. Of course the black wire is connected to the fixture and the ground is spliced to another ground wire at the fixture. Connecting electrical devices and appliances like fan outlet light bulbs etc in parallel is a prefer way instead of series wiring.
Parallel or series parallel wiring method is more reliable instead of series wiring. Wire to the next fixture in the series from the fixture you wired first. Switches and fuses must be connected through line live wire. Using another length of nm cable connect the black wire that you connected to the first fixture the black wire from the second fixture and the black wire from the second length of nm cable together with an orange wire nut. Most light fixtures will have a keyhole shaped hole. If youre using a center mounted ceiling light slide the canopy onto the rod so the nipple shows through the center hole.
When you daisy chain light fixtures youre wiring them in parallel and standard electrical color coding makes this easy to do. Running a series circuit helps to provide the same amount of current to each led. Align the head of the screw into the wider part of the hole and twist the fixture to the narrower part. For many reasons in practice this type of series connection is not done.
