Abstract:
An LED strobe notification device and method for operating an LED strobe notification device is provided. The LED strobe notification device is configured to generate an output at two or more candela settings and is configured to generate the output at the two or more candela settings having a human-perceived pulse duration with a fixed width. The LED strobe device includes: an LED strobe element; and an LED controller in communication with the LED strobe element with the LED controller configured to: receive a candela selection for the LED strobe element, the candela selection selected from the two or more candela settings; receive a command to activate the LED strobe element of the LED strobe notification device; and in response to receiving the command, control the LED strobe element in order to generate the output from the LED strobe element having the human-perceived pulse duration with the fixed width.
