Lighting controller (dimmer and LED lighting control)
Lighting controllers and dimmers · Control method (DALI, 0/1-10 V, Zigbee, Wi-Fi), addressing and scenes, load and supply, channels, dimming and colour-temperature control, bus wiring and mounting
A lighting controller switches, dims and schedules lights — from a wall dimmer or smart dimmer switch to an LED strip controller or the application controller of a networked system. Settle three things before choosing one: the control method and how it must integrate with other systems, the lamp or driver load, supply voltage and number of channels, and the dimming, colour, scene and scheduling functions plus mounting and environment.
Standalone lighting controllers sold separately from luminaires: wall and in-wall dimmers, Zigbee and Wi-Fi smart dimmer switches and LED controllers, LED strip controllers and DALI application controllers. Luminaires with built-in controls, LED drivers (control gear), light and occupancy sensors, emergency-lighting central controllers and explosion-proof control panels are outside this page; LED smart lighting and light sensors have their own pages.

The DALI Alliance describes DALI (Digital Addressable Lighting Interface) as a dedicated digital lighting-control protocol, specified in the multi-part standard IEC 62386, that replaces the one-way, broadcast-like operation of 0/1-10 V analog control with two-way communication: each device can be given its own address and programmed into groups, can report failures and answer status queries, and power and data share one pair of wires whose polarity need not be observed. [1] DALI-2 is the certification programme on the current protocol, adding control devices — application controllers and input devices — that the original standard did not include. [1]
In a DALI-2 system, control gear (for example LED drivers) power the light sources; application controllers use information, make decisions and send commands; input devices such as push-buttons, sliders, occupancy and light sensors provide user and environmental input; and a bus power supply — standalone or built into another device — supplies up to 250 mA, nominally 16 V, to the bus. Each subnet takes 64 control gear and 64 control devices, uses standard 2-core cable (1.5 mm²) in free topology, and allows 300 m maximum between the furthest-apart devices. [3]
DALI commands control (fade to a level, recall scenes, turn off), configure (fade time, scene levels) and query (current level, lamp failure) devices, addressed individually, by group or broadcast; each control gear stores 16 scenes, and certified DALI-2 control gear follow a standardised dimming curve matched to eye sensitivity. [2]
Wireless controllers instead pair with a hub or app: OWON lists Zigbee dimmer switches, in-wall relay modules and LED controllers for homes, hotels and building automation [4], and MVAVA's Wi-Fi dimmer switch sets brightness, scenes and schedules from an app and keeps manual control if the Wi-Fi goes down. [6]
Give the supplier the control method (DALI-2, 0/1-10 V, Zigbee, Wi-Fi, other) and any system it must join, the light source and driver type, load per channel and total, supply voltage, number of channels, dimming, CCT or RGBW control, scenes and schedules, sensor inputs, mounting (wall box, DIN rail, in-line), IP rating, temperature range, certifications and quantity.
02
Match load, supply voltage and channels
OWON lists Zigbee LED controllers rated 40 W at 100–277 V (US) and 100–240 V (EU) with dimming and colour-temperature (CCT) control, a Zigbee LED strip controller for dimming, CCT and RGBW at 6 A on 12–24 VDC, and a battery-powered Zigbee dimmer switch for on/off, dimming and CCT without wall wiring. [4]
Wuyunelek lists a 220–240 V dimmer switch and 20–500 W sensor switches [7], and YUANKY lists 300 W single and dual wall dimmer switches. [8]
Editorial calculation: a 12–24 VDC strip controller's current rating sets the LED load it can drive — at 6 A, 12 V × 6 A = 72 W and 24 V × 6 A = 144 W. If the 6 A is the total across the four RGBW channels rather than per channel, an even split is 1.5 A each; ask whether the rating is per channel or total. [4]
Editorial note: for mains dimmers, check that the dimmer's minimum and maximum load suit the LED lamps or drivers it will control, not only incandescent wattage. [8][7]

Compare what suppliers offer
Suppliers linked to this page list lighting controllers or dimmers; each card links to the page reviewed.
The listings reviewed cover Zigbee LED and strip controllers, smart Wi-Fi and Zigbee dimmer switches and mains wall dimmers. Ask each for the datasheet with load ratings by lamp type, standby power, protocol certification and approvals. [4][5][6][8]

Fill the specification fields with values for your installation
A lighting controller quotation needs values for your installation. The table explains each field, gives published values where a reviewed source states them, and says what to obtain from the supplier.

Buyer questions
How many devices can one DALI line control?
Each DALI subnet takes 64 control gear and 64 control devices, with up to 300 m between the furthest devices. [3]
What does DALI do that 0-10 V cannot?
DALI addresses each device individually or in groups and reads back status and failures; 0/1-10 V is one-way and broadcast-like. [1]
Does a DALI system need its own power supply?
Yes; a bus power supply, standalone or built into a controller, provides up to 250 mA, nominally 16 V. [3]
What load can a smart LED controller handle?
OWON lists Zigbee LED controllers rated 40 W at 100–277 V and a 6 A, 12–24 VDC RGBW strip controller. [4]
