The 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. In the past, some testers used 50% to be a little more practical, but with most batteries, the drop-off is usually pretty quick and the time between 50% and 10% usually is not long. | The 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.
