Controlling LEDs Part 3 - Why Dim LEDs?

Similar to fluorescent, incandescent and other conventional light sources, dimming LEDs saves energy at a roughly 1:1 ratio. This means that if you dim LEDs down to 50% of their light output you will save nearly 50% of your energy usage. So not only do you save by using a more efficient source, you save even more energy by dimming LEDs.

Dimming LEDs also makes them run cooler, which should extend the life of the electronic components of the driver, as well as the phosphor on the LEDs. This will extend their life, doubling or tripling the LEDs lumen maintenance. Research is ongoing to better quantify the relationship of dimming LEDs and lifetime extension.


Dimming any lamp, be it incandescent, CFL or LED enhances ambiance, so whether you are in a restaurant, theater or presentation space, you can create the environment that the lighting designer intended.

Dimming offers many other benefits, including:

• Space Flexibility 
• Dimming control systems provide for space flexibility so that what may be an office space today could easily be converted into a call center tomorrow, or a gymnasium can be used as a theater or cafeteria just by adjusting the control of your lighting. Your home and your workplace should be designed to complement your needs. As your needs change throughout the day, your lighting should adapt as well; bright to read a book, but dim for computer use. Whether you are at home or at work, lighting control can create a comfortable atmosphere to support your activities throughout the day.
• Enhanced Safety 
• Lighting controls can enhance the safety and security of your home. You can control both interior and exterior lights from the car as you approach your driveway to ensure optimal visibility and can even connect to security systems to turn on lights in case of an emergency.
• Increased Productivity 
• Lighting control also increases productivity allowing the user to select the level he/she needs to reduce eye strain and fatigue so that they can work at peak performance for more of the day, or so students can concentrate better and learn more at home or at school.
