An obstruction light is disclosed herein. The obstruction light can include a reflector having a first parabolic portion and a second parabolic portion. The obstruction light can also include a light assembly having at least one array of light sources disposed adjacent to the reflector between the first parabolic portion and the second parabolic portion.

A light emitting diode (LED) floodlight is described herein. The LED floodlight can include a LED housing assembly coupled to a driver assembly. The LED housing can include a number of LEDs mounted on a front side of a LED housing and a number of heat sink protrusions extending from a back side of the LED housing. The driver assembly can include a driver mounted within a driver housing, where the front side of the driver housing couples to the end of the heat sink protrusions that extend from the back side of the LED housing. The LEDs may be coupled to a number of reflectors. The reflectors can include a reflector body having a top portion and a bottom portion. The top portion can form a shape that is an elongated version of the shape formed by the bottom portion.

Load current from an electrical AC supply circuit is monitored so that both high frequency (10-100 kHz), and low frequency (60 Hz) signal current components are measured over certain time periods. A high frequency energy component is measured in an integral fashion, e.g., summing a plurality of samples taken. A certain amount of high frequency energy during a half-cycle is required to indicate an arc event. A certain number of these arc events per half-cycle must occur within a specific time period to indicate the presence of an arc. The root-mean-square (RMS) value of the low frequency energy component is used to determine the severity of the arc. The higher the amperage of the load current arc, the faster the arc fault circuit interrupter (AFCI) will respond by disconnecting the arcing load from the AC supply circuit, e.g., fewer number of arc events necessary for tripping of the AFCI.
