Dimmers are accessories needed for electrical devices in grow rooms, allowing you to increase or reduce electrical input. You can easily control how intense your lights are, make your fans go much slower, change your extractor fan speed and many things that can help keep your grow much more discreet.

They’re super easy to use; all you have to do is connect your dimmer to the device you’re looking to dim. It has a simple knob that you can turn in order to increase or reduce power in your devices.

It’s generally used to control extractor fans; if they’re too fast, the temperature in your grow room much may get much too low, or you may want to reduce the noise produced by your machines when they’re working at full power. The thing about extractor motors is that they work using an electro-magnet, and if they don’t receive a minimum amount of power they won’t spin or they’ll make a terrible noise. Usually, you can lower extractor fans to about half power – it’s rare to get them any lower than that.

Many people think that dimmers don’t work properly, because it won’t adjust their extractor fans to the lowest possible power – this is simply not enough power to get an extractor fan to run normally. These dimmers can fully adjust bulbs from the lowest to the highest setting, but if you want to connect something more potent than that, it’ll need a minimum.

You can use these dimmers with devices up to 300w and a current of 1.6A. Make sure to carefully check your extractor fan’s power in watts and current in amps before you connect them – if you connect anything too potent you’ll definitely end up blowing your dimmers fuse.

If you need more power, some dimmers can deal with heftier devices. This one is designed for small extractors, fans, bulbs, small heaters, air pumps and other smaller devices. If you have any questions, get in touch with us.

How to use this Dimmer:

  • Connect your device to the dimmer.
  • Plug the dimmer into the mains.

  • Adjust the power using the knob.

Dimmer Reviews


Esperaba que regulara mas, pero bien




Su función la hace perfectamente, estoy muy contento con la compra. Gracias a Growbarato.


Cumple su cometido correctamente, baja la fuerza del extractor haciendolo inaudible en mi caso, lo que buscaba y con regalados!


De momento muy contento lo pongo con el intractor y por la noche bajo la potencia con lo cual estoy mucho más tranquilo de que mi vecino no oye nada




Va perfecto para reducir el ruido y el consumo del extractor o intractor


Funciona a la perfección en la descripción pone que no funciona el extractor si se baja más de la mitad de la potencia pero supongo que será según sea el extractor en mi caso prima klima de 760m3 y en la potencia mínima del potenciometro sigue funcionando sin apenas caudal o fuerza de succión pero también 0 ruido


Muy contenta con este Dimmer regulador de potencia , lo uso hasta para el ventilador oscilante y extractor


Perfecto para tener un poco mas de control sobre el caudal de los intractores y extractores


Muy útil si tienes extractor cerrado en la caja no por mucho más me parece . Calidad precio perfecta


No es muy preciso pero funciona mas o menos


Es compatible con RVK 150 E2?gracias


se podría unir a un temporizador para una lampara led de 300W y 1.4amperios?


Rapido y contento con el articulo y el envio


Reduce el ruido muchísimo. Estoy encantado.


es simple y va muy bien
