Telos Lighting Controller - Two-Channel Smart Dimming and Scheduling
Best for: Growers running two lighting zones or fixture types who want automated dimming, ramping and temperature safety without an app or Wi-Fi.
Our thoughts
This is the controller to reach for if you want your lights doing the thinking for you - sunrise and sunset ramping, automatic dimming if the canopy gets too hot, and two channels so you can run a veg zone and a flower zone independently. No app, no Wi-Fi setup faff, just a controller that sits there and works.
The Telos Lighting Controller is a standalone two-channel 0-10V dimming controller built to work with the Telos Dynamic LED range and any other 0-10V dimmable fixture, including mixed setups of LED, HPS and UV lighting. Each of the two channels can be set independently, so you can run different intensities or schedules for two separate lighting zones or fixture types from one unit.
Beyond basic dimming, it adds temperature-driven safety - automatically pulling intensity back or shutting a channel down if canopy heat climbs too high - plus sunrise/sunset ramping that fades lights up and down gradually rather than switching hard on and off, reducing light shock. Settings are battery-backed so a power cut won't wipe your schedule, and the whole thing runs without Wi-Fi or an app, just plug-and-play cabling and a robust housing built for grow room conditions.
How it compares
Sits between a basic manual dimmer and a full app-controlled smart hub.
- Versus the Telos Manual Dimming Controller (also in this range), this adds automation - temperature safety, sunrise/sunset ramping and two independent channels - where the manual unit only offers a fixed dimming dial for a single fixture.
- Versus app-based smart controllers from brands like Grozone or Titan Controls, the Telos unit skips the Wi-Fi and app layer entirely, which means one less thing that can go wrong or need updating, at the cost of remote/phone control.
- Versus running lights straight off a basic mechanical timer, this adds real dimming and safety features a timer simply can't do, particularly the temperature-driven shutdown.
You lose app convenience but gain a controller that just works without needing a network connection in the grow room.
Usage guidance
Wiring in
Connect each 0-10V dimmable fixture to a channel using the supplied plug-and-play cabling - LED, HPS or UV fixtures can be mixed across the two channels as needed.
Setting up zones
Use the two channels to separate veg and flower areas, or to run a primary fixture and a supplemental UV or far-red light on its own schedule.
Temperature safety
Position the temperature sensor at canopy height so the automatic dimming and shutdown react to the heat your plants actually feel, not ambient room temperature.
Ramping
Enable sunrise/sunset ramping to fade intensity up and down over your chosen period rather than switching instantly - this reduces stress on plants used to a slower natural light transition.

Who this is for
- Growers running two lighting zones or a mix of fixture types from one controller
- Anyone using the Telos Dynamic LED range who wants automated ramping and safety, not just manual dimming
- Growers who want smart-controller features without relying on Wi-Fi or a phone app
- Multi-fixture rooms where temperature safety across the canopy matters
Best suited to growers who've outgrown a basic manual dimmer and want proper automated control across more than one zone.
Our take
This earns its higher price over the Manual Dimming Controller by doing genuinely more - two independent channels, temperature safety and ramping are real automation features, not just marketing add-ons. If you're only running one fixture and don't need scheduling, the manual unit will do; if you want your lighting managing itself, this is the one to buy.
One we sell a lot of for growers stepping up to a proper multi-zone setup. Proper kit at a price that makes sense.
