Series vs. Parallel One big question that many have is whether these lights are wired in series or parallel. See below for a couple of quick definitions of both.

Malvern, Penna.&#8212Vishay Intertechnology's two new white LED drivers, the SiP12401 boost controller and SiP12501 boost converter, are optimized for backlighting small liquid crystal displays in ...

The parallel approach isn’t the preferred solution. However, when a large array of LEDs is needed in applications like backlighting and signs, a combination series-parallel arrangement is common.

LEDs are used individually, and when more light is required, they are stacked in series with the same current passing through each one. The voltage across the string increases with each LED added.

Problems you are describing are correct for a set of 5 parallel strings of 5 LEDs in series, but problems with potential cascade failure mode of parallel LED strings were mentioned already.

While addressable LED strips are all the rage, [Mike] from [mikeselectricstuff] has been working on an installation using the more basic two-wire strips that are simply controlled via PWM dimming. … ...

To configure parallel drivers with high-side pass elements, however, the current-sense feedback circuitry must also be on the high side, and it must be able to withstand at least the voltage the ...

In recent years, this process has been used to create arrays of parallel organic LEDs for use in display panels. Producing displays that feature small inorganic LEDs arranged in parallel is a tougher ...

Resistors (Ω) oppose current, are color-coded, and connect in series (Rt = ΣR) or parallel. Current-limiting resistors protect LEDs.
