Find the Right Power

Start with system requirements.

Four decisions narrow the power selection quickly: output voltage, connected load, control method, and installation environment.

01 / Voltage

What voltage does the lighting use?

The driver's DC output voltage must match the rated voltage of the lighting.

02 / Wattage

How much power does the system need?

Calculate the connected LED load, then leave appropriate headroom when choosing driver capacity.

Calculate Wattage →
03 / Control

How will the lighting respond?

Match the driver or power architecture to the dimming or control method used by the project.

Choose a Control Path →
04 / Environment

Where will the power be installed?

Protected and exposed locations can require different enclosure and environmental ratings.

Choose the Control

Start with what you want the light to do.

Switching, dimming, tunable-white control, and color control are different jobs. Define the behavior first, then choose a compatible control path.

01 / Switch

Turn the lighting on or off.

A project that only needs reliable on/off operation does not automatically need a dimming system.

Understand Switching →
02 / Dim

Adjust the brightness.

Dimming can happen through a compatible wall-control path or a controller on the low-voltage side.

03 / Tune White

Change the white-light appearance.

Tunable-white systems coordinate multiple white-light channels and require compatible lighting and control.

04 / Change Color

Control RGB color.

RGB systems manage multiple color channels and require lighting, controller, power, and connections designed to work together.

Control Architecture

Where does control happen?

These are system relationships, not universal wiring diagrams. The actual connection method depends on the selected products.

Wall / Phase-Cut

Control before the driver.

A compatible wall dimmer modifies the input to a dimmable driver, which then powers the lighting.

Wall Dimmer → Driver → Lighting
Low-Voltage Controller

Control after the power source.

A compatible controller manages the lighting on the low-voltage side of the system.

Power → Controller → Lighting
Integrated Control

Control and power together.

Some products combine the control interface and power conversion into one system component.

Control + Power → Lighting
Power & Control Basics

Four things have to agree.

The safest shortcut is not memorizing product names. It is checking the complete system relationship.

01 / Voltage

Match the electrical system.

The lighting, power source, and low-voltage controller must use compatible voltage requirements.

02 / Load

Size the power correctly.

Calculate connected load and leave appropriate driver headroom rather than operating at maximum rating.

03 / Method

Match the control architecture.

Phase-cut, dedicated-signal, PWM, and controller-based paths are different methods with different component requirements.

04 / Lighting Type

Channels matter.

Single-color, tunable-white, and RGB lighting require controls designed for the correct number and type of outputs.

Power & Control FAQ

Common questions before choosing.

Use these as a starting point, then verify the exact specifications and compatibility of the products you intend to install.

How do I know what wattage driver I need?

Calculate the total connected LED load and allow headroom rather than operating the driver at its maximum rating. Use the Wattage Calculator for a quick estimate.

Can I use a 24V driver with 12V lighting?

No. The driver's DC output voltage needs to match the rated voltage of the LED lighting.

Does “dimmable” mean any dimmer will work?

No. The dimmer, driver, control method, lighting load, and wiring architecture all need to be compatible. Check the exact product documentation.

What is the difference between wall dimming and an RF controller?

Wall dimming commonly acts through a compatible dimmable-driver path. An RF controller commonly operates on the low-voltage side between power and lighting.

Can one controller run fixed white, tunable white, and RGB?

Only when the controller is specifically designed for the required voltage, channel arrangement, and lighting type. A controller's feature list does not make every system compatible.

Where should I start if I am unsure?

Use the LED System Builder for the complete component path, or read the Dimming & Controls Guide if you first want to understand the methods.
