The amount of continuous runtime (in minutes) until the light output drops to 10% of its original value (measured 30 seconds after turning the light on). This test is done in an integrating sphere just like the lumen test with light output measured every 15 minutes. 10% of brightness probably gives inflated runtime numbers.
