Why are the LED-X and Optix LEDs described as having directional, wide, or hybrid optics?
A “directional” optic projects a LED beam signal over a minimum area of 20 degrees to the right and 20 degrees to the left on a horizontal plane and from 10 degrees up to 10 degrees down on a vertical plane. A “wide” optic projects a signal in a defined horizontal arc substantially beyond 20 degrees to the right and 20 degrees to the left on a horizontal plane. The device must also project a beam signal over a minimum area of 5 degrees up to 5 degrees down in the vertical plane. A ’hybrid’ optic combines the directional and wide optic. The LED signal incorporates some light in the ’directional’ spread and some in the ’wide’.
