This is the Rako RMT500, a compact 500W RF dimmer designed to fit through a standard down-light cut-out and working with dimmable GU10 LED lamps, tungsten, and low voltage halogen lamps. It uses trailing edge dimming technology, which gives it smooth quiet dimming of electronic transformer fed loads and it maximises dimming performance of most GU10 LED downlights.

Please note: this item is non-returnable; due to the fact that it has an electronic component, we cannot take this item back for a refund.

This wireless dimmer is connected in-line before the first light fitting in order to enable dimming of up to 500W of trailing edge dimmable loads, and it can be controlled from any Rako Rakom RF device, for example the Rako RCP/RCM push button RF wall-plates.

Videos of Rako Wireless and Wired LED Dimming Solutions for Home or Office

We at Sparks love the people at Rako and their great products, and we're so glad that they put out quite a few videos to introduce some of their dimming solutions. They offer a flexible and extendable dimming solution "at the click of a button" or at the "touch" of the iPad/iPhone app for both domestic and commercial environments. In this article, we're introducing three main videos: the Rako whole house dimming and scene control setting system, the wireless LED dimmer controller, and the Rako LED dimming control solutions. Rako Whole House Dimming and Scene Control Setting System - Video The Rako whole house dimming and scene control system is great for both residential and commercial applications. Via the programmable scene control panel, you can change the lighting scene setting. For example, in the kitchen you can have scenes like food prep, family dining, entertainment, party, etc. In the living room you can easily use the Rako iPad / iPhone app to set all the lights ON, or have scenes like: watching a movie (home cinema), reading a book, relaxing, etc. Also, you can control the lights, the blinds, and the curtains in multiple rooms from a single control point, turn all the lights off from a single point, link the Rako lighting to a security system, or schedule timed events. Rako Introduces the Wireless LED Dimmer Controller The wireless dimmer controller Rako RMT500 is a single-ended dimmer, a wireless module, ideal for the latest LED lamps, with control over IP by using Rako bridges and wall control panels. This LED dimmer is silent and it can be addressed by pressing the button on the front of the dimmer. It comes with 16 scenes and has longer fade rates. Follow the slideshow and watch the video below to find out more. Rako LED Dimming Control Solutions - Overview There are so many ways to control the LED lights, and Rako provides quite a wide range of solutions for dimming the LED lights, whether mains dimmable, leading edge, and trailing edge (including the GU10 LED lamps, the LED fittings with a Mains Dimmable driver).
