LED Downlights

LED DownlightsCombining dimmer switches and downlights has long been a staple of energy-efficient lighting design in residential and commercial settings. One problem is that users often leave the dimmer at full power to get more light. The LED downlight solves that problem because it uses less energy than its dimmed down incandescent light counterpart.

However, LED downlights aren’t exact replacements for incandescent lights. For one thing, you can’t use them with incandescent dimming controls. But you can use LED lights with controls designed for LED lighting systems.

The key to a good design is to think of LED downlights as a distinct lighting system, rather than just a variation of the incandescent one you would have installed.

Consider, for example, the fact that you can run quite a few more 21W LED fixtures on a given circuit than you can run 100W incandescent ones.

  • In a conference room, you might have put the overhead fixtures on one circuit and the accent lights on another and now you can put them on the same one.
  • In a hotel ballroom, you might have used three or four circuits for just the lighting and now you can use just one.
  • Eliminate shadows by adding LED strip lighting around the room perimeter to supplement the downlights; all this lighting can be on the same circuit.

Running one circuit instead of two is cheaper. If you control it with an occupancy sensor, you greatly exceed the energy savings of the incandescent dimmer system but provide the same light levels occupants got by leaving the dimmer all the way up.
