The problem is one of perception. Somewhat automatically, we think about our flashlights based on their highest output. We only realize how phony that is when we acknowledge the early stepdown most turbo modes require. We would do better to categorize our lights based on the output level they can hold steadily.
Based on its highest output, for instance, my Zebralight SC62w is a "930-lumen" flashlight. But even with its PID temperature control, the SC62w can only hold that level for a few minutes. In
tests by CPF member GeoBruin, PID reduced output continuously from the maximum of 930 lumens until it stabilized at 60% of max after only 5 minutes. That's a level that can be maintained steadily. I need to describe my Zebralight, therefore, as being a "560-lumen" flashlight, rather than anything higher.
Once you make that psychological adjustment, there is nothing phony about having a 930-lumen turbo mode available as an option.
