Very rarely we're asked about LED Amplifiers and Power Repeaters and whether or not we supply them.
The simple answer is that we don't supply either of these, for the reason being that our RGB/RGBW LED Controllers/Strip Dimmers are smart devices, which can sync between multiple controllers, thus negating the need for a Power Repeater.
A few companies still tend to rely on previous generation hardware, where LED Amplifiers/Power Repeaters are required, because a Controller might be unable to sync with anything else; by using a master controller, multiple power repeaters can then be hooked up as desired. The need for such devices may simply come down to a question of cost-effectiveness, being primarily used for large installations, whereby installing several power repeaters may be preferable to several controllers, but it can also come with problems. We find this to be a rarity these days and feel that there's little need to explore this option for your basic lighting requirements.
