Total lumens of output, measured in an integrating sphere after the light has been on for 3 minutes. This gives time for the LED to get hot and the battery voltage to sag which will usually decrease the output. | Total lumens of output, measured in an integrating sphere after the light has been on for 3 minutes (actually may be 30-120 seconds like some of the readings below).
