LEDs only cast light in 180 degrees. Almost all other types of light, unless focused by the fixture itself, will cast light 360 degrees around the source.
Focusing the light—and any heat the light makes—dictates how much material is used in the light’s casing. The more materials used, the bigger the light, and the more expensive the fixture.
LED’s, or light-emitting diodes, are so small, they can be arranged in ways that traditional lights—like filament bulbs and CFLs—cannot. In an ultra-thin flat-panel style installation, they are arranged in a grid, all facing one direction, which works perfectly with their 180-degree lighting casting.
Because LED’s are tiny, flat, and create very little heat, they are perfect for flat, thin applications. While many LED lighting fixtures are “integrated,” meaning that the light, the casing, and the driver all in one unit, ultra-thin downlights from TCP are not. Our ultra-thins separate the biggest part of an LED and allow you to relocate it, giving you the thinnest possible light source.
Because the lifespan of an LED regularly exceeds 40,000 operational hours you’ll rarely if ever, have to change the light. In fact, it’s more likely you’ll change the house or the floor plan before the light goes bad!
