Usable Light Tool 2.2




High-power LED datasheets publish typical flux and other performance values at a lab controlled junction temperature of 25°C.  As such, it is difficult to determine the expected level of usable light in a "real world" environment.

The purpose of this tool is to provide a true "real world" evaluation and comparison of high-power LEDs by taking into account the effects of 7 critical relationships.
