Zigbee LED Drivers and Controllers – UK Buyer’s Guide
Samotech stocks three Zigbee LED control devices. They live on two product pages – the Zigbee LED Driver (with two variants, CCT and RGBCCT) and the Zigbee LED Strip Controller – but functionally they’re three distinct devices for three distinct installation scenarios. Picking the wrong one usually means buying the wrong input-voltage device for what your circuit actually provides.
The headline distinction: only the CCT variant is a true “driver” in the electrical sense – it takes 220–240V mains and converts to constant current for the LED. Both other devices are controllers – they need a separate DC power supply (which they don’t include) and switch / dim the DC output. The RGBCCT “driver” carries that label on the product page because it sits in the same Samotech product line, but per its Sunricher manufacturer manual it’s classified as a “4 in 1 Universal Zigbee LED Controller” with a 12–48V DC input. This guide explains what each one is, what input voltage it needs, what loads it can drive, and which install scenario it fits.
The actual difference – driver vs controller
A complete LED installation has three things in line: mains power (230V AC from the wall), a power conversion stage (drops the voltage and conditions the current for the LED), and the LED load itself – strip, downlight or panel.
- A driver does the power conversion. Mains in, low-voltage and current-controlled out. The CCT model in this range is the only true driver of the three.
- A controller sits on the LED side of the power conversion. Low-voltage DC in, switched and dimmed low-voltage out. The RGBCCT model and the Strip Controller are both controllers – they need a separate PSU in front of them.
Get this wrong and you either end up trying to feed mains into a controller (which will damage it) or trying to find a 12V PSU for an actual driver (which already has one built in). Get it right and the device drops cleanly into its part of the circuit.
Three products at a glance
Zigbee LED Driver (CCT) – the mains-in option
The CCT variant is the Sunricher SRP-ZG9105N-65CCT500-1500. It’s the only product in this range that takes 220–240V mains directly and converts it for the LED. Constant-current driver, 2-channel output (warm white + cool white), designed for tunable-white downlights, ceiling panels and similar fixtures.
Specifications taken from the manufacturer manual:
- Input: 220–240V AC or DC, 50/60Hz, absolute range 196–264V
- Output: constant current 500–1500mA, NFC-selectable, default 1050mA; output voltage 6–54V DC
- Max power: 65W
- Channels: 2 (WW + CW) for tunable CCT
- Efficiency: > 88% at full load; power factor: > 0.97
- Surge protection: 2kV L–N
- Construction: Class II isolated plastic enclosure
- Operating range: –25°C to +45°C
- Warranty: 5 years
- Dimensions: 123.9 × 78.8 × 30mm
What makes it different from a generic CCT driver
- NFC programming. Hold an NFC-capable phone (with the “SR NFC Tool” app) to the unit and configure target current, dimming curve (linear or logarithmic), power-on state, fade time, corridor-dim, constant-lumen output and push-switch type – all before applying power. Safer than live programming, faster than DIP switches.
- Push-dim wall-switch input. Wire a momentary push switch into the dedicated PUSH terminals. Click to toggle, press-and-hold to ramp brightness up and down. Works alongside Zigbee control.
- Touchlink + Zigbee Green Power. Pair directly to a Zigbee remote (Hue Dimmer, IKEA Tradfri, etc.) with no hub. Bind up to 30 remotes per device, or up to 20 Zigbee Green Power switches.
- Amplitude / CCR dimming with smooth deep dimming down to 0.01% of max current.
- MCB compatibility table in the manual – up to 15 drivers on a B10 breaker, 50 on a C25, etc. Useful for commercial planning.
Use this for: tunable-white downlights, recessed COB fixtures, ceiling panels, or any fixture that quotes a current rating in milliamps rather than a voltage. Single mains feed at the fixture, no PSU in the circuit. £35.99.
Zigbee LED Driver (RGBCCT) – the 5-channel multi-mode controller
The RGBCCT variant on the LED Driver product page is the Sunricher SR-ZG9101EA-5C-A. The product page lists it as a driver because it sits in the same SKU; the manufacturer manual classifies it as a “4 in 1 Universal Zigbee LED Controller”. Either way it takes 12–48V DC from an external power supply and provides 5 channels of switched / dimmed constant-voltage output.
Specifications from the manufacturer manual:
- Input: 12–48V DC (not mains – this is the critical point)
- Output: 5 constant-voltage channels, common-anode
- Per-channel load: 8A at 12V or 24V (96W – 192W); 6A at 36V (216W); 4A at 48V (192W)
- Total load cap: 20A across all channels
- Mode selector: on-board DIP switch with 4 positions – DIM, CCT, RGBW, RGB+CCT
- Push switch input for wall-rocker dimming
- Self-forming Zigbee network – no coordinator required
- Touchlink, Green Power, Find & Bind supported
- Operating range: –20°C to +50°C
- Dimensions: 170 × 59 × 29mm
What makes it different from a basic strip controller
- 4 device modes in one unit. Flip the DIP switches on the board to switch between DIM, CCT, RGBW or RGB+CCT modes. Useful where the install changes over time, or you’d rather stock one device for multiple strip types.
- Wider DC range (12–48V). Most consumer controllers max out at 24V. Architectural and commercial 36V or 48V strip runs are supported natively here.
- 20A total load capacity. Roughly 480W at 24V across all 5 channels – well above what compact strip controllers can handle.
- Push-switch input. Like the CCT driver, accepts a momentary wall switch for traditional click-and-hold dimming alongside Zigbee.
- Self-forming Zigbee mesh. Multiple controllers link directly to each other without a hub, useful for simple multi-zone wired-switch retrofits.
Use this for: larger or commercial strip installations, 36V / 48V architectural strip, retrofits where push-dim wall-switch control is wanted, or any scenario where you’d rather have one SKU that can be redeployed across DIM / CCT / RGBW / RGB+CCT applications. £37.49.
Important: this device replaces only the controller stage. You still need a separate 12V / 24V / 36V / 48V DC power supply between mains and the controller. If your strip kit didn’t come with a PSU, factor in £20–40 extra for a sensibly-rated one.
Zigbee LED Strip Controller – the compact option
The strip controller is a GLEDOPTO Mini LED Controller Pro – a different category of device from the Sunricher 5-channel controller above. A 7 × 3.6 × 1cm flat board designed to be hidden inline behind a TV, under a cabinet, or inside a tight strip channel. Sold separately on Samotech’s “Zigbee LED Strip Controller” product page.
- Input: 12V or 24V DC (typical strip-kit voltages)
- Output: 5-channel constant voltage, RGB+CCT capable
- Independent W channel – dim white separately from RGB
- Zigbee 3.0 – joins any Zigbee 3.0 hub (Hue Bridge, Home Assistant via Zigbee2MQTT / ZHA / deCONZ, SmartThings, Tuya, etc.)
- Dimensions: 70 × 36 × 10mm (the slimmest of the three)
- Warranty: 12 months
What it gains and what it gives up
- Half the price of the Sunricher RGBCCT (£19.99 vs £37.49).
- Slim enough to actually fit in the slot behind a TV next to the 12V brick. The Sunricher 5-channel controller (170 × 59 × 29mm) won’t.
- Independent W channel from RGB – dim white deep without RGB bleeding in, a common failure mode on cheaper combined controllers.
- Narrower input range: 12–24V only, no 36V or 48V support.
- No on-board DIP switch – fixed to one configuration, no mode-swapping.
- No push-switch (PUSH DIM) input.
- Standard 12-month warranty rather than the Sunricher’s 5-year.
- Lower max load capacity, typical of compact strip controllers.
Use this for: behind-TV strip, under-cabinet kitchen lighting, bedhead accent strip, basic home LED kit retrofits, or anywhere the controller needs to physically disappear. £19.99.
Which one should you buy?
- Wiring up CCT downlights, ceiling panels, or COB fixtures from scratch? Single mains feed at the fixture, no PSU in the circuit? – LED Driver (CCT). £35.99.
- Large or commercial strip install, possibly at 36V or 48V, possibly with multiple strip runs from one Zigbee point? – LED Driver (RGBCCT). Higher load capacity, multi-mode DIP-switch flexibility. £37.49 + separate PSU.
- Retrofitting smart control into an existing 12V or 24V strip kit at home – behind-TV, under-cabinet, bedroom accent? – Strip Controller. Compact, cheap, drops inline between your existing brick and strip. £19.99.
- Want push-switch (wall-rocker) dimming from a traditional wall switch position? – either the LED Driver (CCT) for CCT fixtures or the LED Driver (RGBCCT) for strip. Both have PUSH DIM inputs. The Strip Controller does not.
- Need to commission a commercial install via NFC before powering? – LED Driver (CCT). The only model in the range with NFC programming.
- Want a single device that can be re-deployed across different strip types over time? – LED Driver (RGBCCT). The DIP switch lets you change between DIM, CCT, RGBW and RGB+CCT modes on the same unit.
Installation differences
LED Driver (CCT) – mains-side wiring
- Isolate the lighting circuit at the consumer unit.
- Wire the mains feed (L + N) into the driver’s mains input terminals.
- Wire the WW and CW LED outputs to your CCT fixture or strip.
- (Optional) Hold an NFC phone to the driver and configure output current, dim curve, fade time, etc., before powering on.
- Power on. Pair to your Zigbee hub or Touchlink directly to a remote.
Mains-side install. Treat it as electrical work – a competent person should be doing it, and notification under Part P may apply depending on the zone.
LED Driver (RGBCCT) and Strip Controller – low-voltage wiring
- Confirm your DC power supply’s output voltage matches your strip (12V, 24V, 36V or 48V) and is current-rated for the total strip load.
- For the RGBCCT controller: set the on-board DIP switch to your strip type (DIM / CCT / RGBW / RGB+CCT) before wiring.
- Wire DC+ and DC– from the PSU into the controller’s input terminals.
- Wire the strip’s channels (V+ / R / G / B / W or similar) into the controller’s outputs per the manual’s pinout diagram for the chosen mode.
- Power on the PSU. The controller boots and is ready to pair to a Zigbee hub.
Low-voltage work only – no mains exposure beyond plugging in the PSU. Doable by any competent DIYer with a screwdriver and the strip manufacturer’s pinout.
FAQ
Can I feed mains into the RGBCCT “driver” or the Strip Controller?
No. Both are low-voltage devices despite one being labelled a driver. The RGBCCT accepts 12–48V DC; the Strip Controller accepts 12–24V DC. Feeding either of them mains will destroy them. Only the CCT variant of the LED Driver takes 220–240V mains.
Why is the RGBCCT variant labelled as a “driver” if its manual calls it a controller?
It sits on the same product page as the CCT driver because Samotech groups them by Zigbee-enabled LED control products for new installs. The manufacturer (Sunricher) classifies it as a “4 in 1 Universal Zigbee LED Controller” because, electrically, it’s a controller – it switches DC and doesn’t do mains-side power conversion. For installation planning, treat it as a controller: it needs a PSU in front of it.
Why are there two controllers? Aren’t they the same thing?
No. The RGBCCT (Sunricher) is a professional-spec controller with wider voltage range (12–48V), higher current capacity (20A total), 4-mode DIP-switch selection, push-dim input and a 170mm enclosure. The Strip Controller (GLEDOPTO) is a compact consumer device – 12–24V only, single fixed mode, no push-dim, but 70mm wide and half the price. Different jobs.
Do any of these need a Zigbee hub?
The two Sunricher devices (CCT driver and RGBCCT controller) support Touchlink and direct binding to Zigbee remotes (Hue Dimmer, Tradfri, etc.) with no hub. They also support Zigbee Green Power switches directly. For app control, scenes, automations and Home Assistant integration, you’ll want a hub. The GLEDOPTO Strip Controller pairs to a hub via the standard “add new device” flow.
Will these work with the Hue ecosystem?
All three are Zigbee 3.0 compliant and pair to a Hue Bridge as standard dimmer / colour bulbs. Brightness, scenes and (for the colour-capable models) colour control are exposed in the Hue app. Some advanced features – the CCT driver’s NFC config, the RGBCCT controller’s DIP-switch modes – are device-side rather than exposed through the hub.
What is NFC programming on the CCT driver and do I need it?
NFC lets you configure the CCT driver before powering it on. Hold an NFC-capable phone (any modern Android, recent iPhone) running the “SR NFC Tool” app over the unit to set: target output current, dimming curve (linear or logarithmic), power-on state, fade time, corridor-dimming behaviour, constant-lumen output mode, and which external-switch type is wired in. Optional – defaults work for most installs – but valuable for commercial commissioning where multiple drivers need consistent behaviour set offline.
How does push-dim work on the two devices that support it?
Wire a momentary push switch (not a maintained rocker) to the device’s dedicated PUSH terminals alongside the mains or DC feed. A click toggles the LED on or off; press-and-hold ramps the brightness up or down. Lets you keep a traditional wall-switch UX even after the rest of the system goes Zigbee. Available on the LED Driver CCT and the LED Driver RGBCCT; not on the Strip Controller.
What’s the warranty on each?
The CCT driver has a 5-year manufacturer warranty from Sunricher. The RGBCCT controller and the GLEDOPTO Strip Controller carry standard 12-month warranties.
