This little Mini-Dimmer is really useful, maybe more to the DIY folks than others. It connects between the power supply and the LEDs, and has buttons to control on/off (press and hold the center button) and to select about 10 LED brightness levels (by momentarily pressing the center button). It also has a Mode button for various blinking and flashing modes. In the normal dimmer mode, there are about 10 brightness levels. In other modes, the center button adjusts the speed of the flashing. You don’t have to use all those modes. Once it’s back in the dimmer mode, the only button you’ll likely ever use is the center button to adjust the brightness.
The Mini-Dimmer is ideal for applications where a fixed LED brightness level is desired and not often changed, such as in a china cabinet or for accent lighting. Ideally, if you can power it from an outlet that’s controlled by a clicker or wall switch, you’ll only adjust the Mini-Dimmer occasionally to change the brightness level, not to turn the LEDs on and off. You’ll do the on/off part by controlling the outlet rather than the dimmer, and (here’s the best part) when you do it that way, the LEDs will remember their previous brightness setting every time you turn the outlet back on. This works well since using the Mini-Dimmer’s on/off button to turn the LEDs on and off has the annoying result of also changing the brightness by one level every time you turn it off. So you’ll have to press the center button a few times every time you turn it on to select the desired brightness level. But not if you use a switched outlet to do the on/off part.
You can also use the Mini-Dimmer TOGETHER with a motion detector (available on this site)! This works great for an application such as a motion-controlled nightlight, such as under a bed or crib. Just order the cheapest LEDs for this kit since you don’t need them to be bright, just to distribute the light evenly along the bed or crib. Then you’ll want to connect the power supply to the input of the motion detector, then connect the motion detector output to the input of the Mini-Dimmer, and finally from the Mini-Dimmer output to the LEDs, all using the easy spring connectors available with most kits or separately on the site. Then every time the motion detector turns on, the LEDs will turn on at their pre-selected brightness level which was set (and remembered) by the Mini-Dimmer. Slick!
