As LED lighting grows in acceptance and popularity, so does the need for better and more ranging color quality. Traditionally, LED lighting gave off a stark white, cool glow that was harsh on the eyes and made it difficult to use as a primary lighting source. Warm-dim LED technology has toned down that cool coloring, dynamically shifting the current and future applications of LED lighting management systems. Dimmability with a warm glow effect creates more opportunities than ever for LED lighting management systems.

Gradual warm dimming allows users to dim LED lighting levels in the same tones as traditional bulbs, creating a cozier, less clinical affect. In a market already featuring both indoor and outdoor options, stage and entertainment applications, and opportunities for industrial lighting, warm-dimming has an important place in the LED space.

 

LEDs have traditionally dimmed at the same color temperature as when they were at full power. With the advent of warm dimming solutions, LEDs are now able to produce the same aesthetically pleasing effects as an incandescent light or halogen lamp. This occurs because of red or amber LEDs added to the fixture or lamp, creating an effect that is particularly suitable for application in homes, restaurants, hotels, spas, resorts and other locations where the intended atmosphere is cozy or relaxing. Warm dimming enhances the aesthetics of LED lighting, simultaneously enhancing the wellbeing of individuals in LED-lit environments.
