Sofirn SD05 Flashlight Output & Thermal Analysis

This analysis was performed for the evaluation of the Sofirn SD05 as a bar light for MTB Night Riding. See the full review / posting on MTBR's Lights & Night Riding Forum.
Sorry for the audio at the beginning; a background exhaust fan was picked up more than I thought it would be! This is a raw unedited video.
