Fenix CL28R Turbo Burn Down (timelapse)

This is an experimental video that resulted from a question that we all ask regarding lighting systems. How long does a light hold turbo output? More specifically, what is the actual burn down in a realistic setting? Very few vendors provide burn down curves and those are only valid for theoretical environments (i.e. lab conditions where the lumen output can be precisely measured over time with an integrating sphere). Actual burn down outdoors is dependent on a number of conditions such as temperature. This video is a timelapse of the burn down from Turbo for the Fenix CL28R lantern. The lantern was turned up to maximum output and left at that setting. The duration of the timelapse was based on obtaining an idea of how long the lantern could provide some level of reasonable output in a camp setting. I filmed another review in advance of the timelapse so that I could start in a very dark environment and ensure that the 1/8 moon (which was behind the camera) would set before the lantern output got too low. It was below the horizon by about 10:10 PM. The timelapse was filmed with an iPhone14 Pro MAX, but this camera was not able to show the entire extent of the lantern&illumination. Some of the step-down effects could only be observed beyond the field of view captured by the iPhone. I have since upgraded my Filmic Pro app and will likely add a low-end cinema cam in the future for even better results from such videos. Thanks for your time and I hope you obtained...
