Imtra Lighting Emden-Medium LED, Stainless Steel, Warm/Blue | Master (Dimmable), 10-30VDC, IP67

A robust precision-made dimmable Bi-Color LED downlight fixture built for harsh environments. This "slave" model from the Emden family features both blue and white operation. For dimming control of both colors, a single Emden bi-color "master" must be used in the circuit. In this case a single (or multiple) single throw momentary push button switche(s) are used to control and synchronize the entire circuit. For basic 3-position (white/off/red) on/off control without dimming, a "master" is not required. For dimmed circuit: To switch the lights on or off, press briefly on the remote momentary switch. Brightness can be adjusted by holding down the switch. To reverse the dimming phase, release the switch briefly and press again within one second. The LED light can be dimmmed to a minimum (10%) or pushed to maximum bright-ness (100%), and will remain at that respective level. The light keeps this brightness until the next change. A double-click changes between the blue and white light.
