5V, 12V or 24V — how do I choose the right plug-in adapter for my LED lights?

Plug-in adapter with an On/Off switch or without one — which is more practical?
The switch mainly changes how convenient the light is to control

5V, 12V or 24V — how do I choose the right plug-in adapter for my LED lights?
I’m replacing a couple of LED power adapters around the house and realized there are a lot more versions than I expected.
Some are 5V, some are 12V or 24V, and then there are different wattages even when the voltage is the same.
Is the safest way to choose one to match the voltage printed on the LED light first, then make sure the adapter has enough wattage?
I’m also seeing different barrel connectors and some versions with a terminal block, so I’m trying to figure out what actually needs to match before ordering.

Yes. Start with the required DC output voltage of the connected lighting.
A 5V device needs a compatible 5V adapter, a 12V device needs 12V, and a 24V device needs 24V. After that, check the required wattage/current and make sure the selected adapter has sufficient capacity.
Also confirm the physical connector. For example, current LightingWill models commonly use a 5.5 × 2.1mm DC connector, while several versions also include a terminal block for bare-wire connections. The current collection includes 5V, 12V and 24V plug-in adapters across multiple power ratings.

Many plug-in adapters in this collection are available in very similar voltage and wattage combinations, but some include an inline On/Off switch while others do not.
The right version depends mostly on how the connected lighting will be controlled.
Answered by LightingWill
Lighting specialist
A version with an inline On/Off switch is useful when the LED lighting does not already have a convenient controller or wall switch.
For example, the current 12V 12W switch model provides:
- DC 12V output
- 12W / 1A capacity
- AC 100–240V input
- 5.5 × 2.1mm DC connector
- Inline On/Off switch
- Included terminal block
The standard non-switch versions provide the same basic AC-to-DC power function but rely on another control method or unplugging the supply when power needs to be removed.
White and black housing should mainly be treated as an appearance choice when the electrical specifications of the selected variants are otherwise the same.
Application case
Used the 5V adapters for two small display shelves instead of one larger power supply
I have two small display shelves on opposite sides of the room and originally thought about powering everything from one supply.
Once I started planning the cable runs, using a separate small adapter for each shelf made more sense.
Both lights are 5V and don’t use much power, so I went with the 15W adapters.
It also means I can unplug or move one display without affecting the other one.
The adapters are hidden behind the shelves, so once everything was installed there wasn’t really anything visible except the lighting.
Answered by LightingWill
The current 5V 15W adapter provides DC 5V, 15W / 3A output, AC 100–240V input and a standard 5.5 × 2.1mm connector. The current listing is supplied as a 2-pack and includes terminal blocks for compatible wiring connections.
It is intended for indoor LED strip, cabinet, decorative and small low-voltage lighting projects.
